In 2014, the OpenROV team attempted to find and film the wreck of the SS Tahoe. The expedition was modestly successful, especially in terms of testing equipment, but left us wanting more. We're going back, and this time we're using the new OpenROV Trident.
For this post, I would like to share the schedule of one mission day, so you can have an idea of what’s going on from the moment the alarm clock wakes us all to the time when we finally go to bed. We wake up usually at 7 am to prepare breakfast. At 8 am, we decided to start with an aerial prospection of the ancient harbor. In order to do so, we had first to put some markers along the shore so the archeologists can have several reference GPS points to have a geographical referenced 3D model and an orthophotoplan. For this, it is important to know that we use local products that we don’t have to transport in our luggage. The lighter we are, the better it is. As soon as we arrive somewhere on a mission, we spot quickly a tourist beach store and buy several colorful foam rollers. They are very convenient because first, they are really cheap. Then, you can cut them easily in small pieces and even a small piece float perfectly. After buying two of them in the city, we drove to the ancient site as early as possible. Here is the trick : if you wait too long, the sun is reflecting badly in the water and the aerial images are not usable for any kind of 3D because of the mirror effect (the sun is at the exact same position on each picture). At 9h30, we dispatched the markers first on the beach, then in the water. In order for the markers not to move in the water, we had to come up with an idea. The best we could find in the store were several pieces of rather rigid water hose on top of which we placed pieces of foam (see picture). Once our markers were set, we launched the drone in the air… to realize we were too late in the morning. The sun was already too high in the sky at about 10h30. At least our positioning markers were set for the following morning. At about 11 am, we were back at the marina to get ready to return to the quarry that is located at about 45 minutes from our small harbor with our sailing boat. We anchored at about 12h30. After a small snack, we jumped in our wetsuit and prepared our diving equipment. Diving at this period of the year (mid September) in Albania, you have to take into account that the sun light is too low already at about 4 pm. So, the best is to dive between 12:00 and 14:00. After 15:00 the light is seriously lacking. This dive went smoothly and Philippe managed to make the photo acquisition of the first underwater zone (20m by 30m) thanks to the guiding rope held by Christophe and Sebastien on each side of the rectangle. During the dive, Julien launched from the boat the drone in the air, to make the aerial photo acquisition of the area (see previous post). At about 15h30, everyone was back on board. At 16h30, we left our anchorage and arrived in our birth at about 17h15. At 18h00, Christophe was already compressing air in our 4 diving tanks (two 12 liters and two 10 liters) thanks to the small air compressor that our Albanian contact rented us. Chris will need between 1h30 and 2 hours to have them fully loaded for the following day. Philippe was copying and editing the underwater pictures of the day in the boat, while Sebastien and Margaux were preparing the deck of the boat for the following day. In the meantime, Antoine and Julien went straight to the house we rented on the harbor to start working on the 3D model (Julien) and the drawings of the day (Antoine). Margaux followed them to start cooking the dinner. At about 19h30, we realized that it was Margaux’ birthday !!! Damn, we almost forgot !!! So, Julien (who has started a 3D process) and Sebastien rushed in town to buy her a magnificent red Albanian T-shirt with the two black eagles. Back at the house at 20h30, we had a more than wonderful diner, thanks to our "cooking wizzard" Margaux, discussed about the weather for the next days (which is really important to us) and decided to return earlier to the lagoon the following morning. At about 23:00, we were exhausted, but the computer that was processing the 3D models was seriously bugging. After trying several things, we decided to shut it down for the night… At about midnight - 1:00 am, everyone was sleeping : Margaux and Christophe in the house, and Sebastien, Julien, Philippe and Antoine in the boat. It was now mosquitoes' time !!!
Lost Sharks are lesser known species of sharks and their relatives which receive little to no attention compared to more charismatic species such as the Great White Shark (Carcharodon carcharias). Often times, it is these Lost Sharks that are exposed to much greater risks of extinction. Yet with little public attention, their needs for conservation management and scientific research can go unrecognized. One such example are the true sharks and flat sharks (rays) that utilizes San Francisco Bay. According to historical literature (Byers 1940, Herald & Ripley 1951, Herald 1953, de Wit 1975, Ebert 1986, Russo 2013), there have been six species regularly caught over the years. The bays regular visitors are Sevengill Sharks (Notorynchus cepedianus), Soupfin Sharks (Galeorhinus galeus), Leopard Sharks (Triakis semifasciata), Brown Smoothhounds (Mustelus henlei), Spiny Dogfish (Squalus suckleyi), and Bay Rays (Myliobatis californica). Since many people don’t realize that these Lost Sharks are in the Bay to begin with, it should be no surprise that little is known about their ecological roles in this system. To help unravel the mysterious lives of the Lost Sharks in San Francisco Bay, this project will use an Open ROV to support our research endeavors. Although much of the data we would like to collect could be done through SCUBA surveys, the water conditions in San Francisco Bay are highly challenging and the high boat traffic make it too dangerous for us to attempt. The Open ROV will therefore help us to visualize the underwater ecosystem including marine life that we cannot collect with our fishing methods. It will also help us understand the environmental conditions that cannot be easily explored or sampled from the topside of a boat. References: Byers, R. D. (1940). The California shark fishery.

This is my second OpenROV dive at Lake Tenkiller in eastern Oklahoma. Tenkiller is a fresh water lake with relatively clear water and good visibility - good for diving.
Here's the most provoking view we got of the object from the sidescan sonar. Passes from other angles made the object appear amorphous, backing up the idea that Site 001 is merely a large rock. We were ready to start packing up the sonar, but just as we were finishing up our last set of transects we got this image which one must admit looks very boat-like! Our next objective would be to try and locate the object visually using our Trident prototype.
Sad news, we cannot deploy ROV on Ascension... When going to Ascension you have to apply for a permit be it if on holiday or doing research, this was the last step of the trip going forward. The Uk government has a final say over wether or not certain equipment can be used on the island as contains potentially sensitive material being a large military installation. They denied the use of ROV so there is no point continuing to go there. However, we are looking for alternatives to the ascension island, places near to hydrothermal vents or subsea volcanos using a google earth plugin at:<a href="http://bit.ly/2eVVspL" data-longurl="https%3A%2F%2Fwww.interridge.org%2Firvents%2Fmaps">interridge.org/irvents/maps</a>. So should still be exciting non the less although the time frame has become delayed and will keep this informed as i know.
Over a year ago, while diving in an alpine lake in upstate New York, we paid the exploration tax: <a href="http://bit.ly/2eTwIi1" data-longurl="http%3A%2F%2Fbit.ly%2F2eTwIi1">openexplorer.com/expedition/foreverex</a> I had all but given up hope that the OpenROV we lost would ever be recovered. Then, last month, a local diver contacted me. After almost 18 months on the lake floor, somewhere between 30 and 70 meters deep, Honeycomb has returned! This little bot is in pretty bad shape, but it can be rebuilt. It will dive again. Join us as we systematically disassemble this legendary robot and rebuild it. This is Honeycomb Rising!
A quick update to those following this project. At the end of September, after several month of work with the fishers, the federal fisheries agency created two completely protected marine reserves to protect the fish spawning aggregations! Thanks to everyone involved in the project. We´ll continue to explore new aggregation sites.

July 5th 2012, Clarence W. Holmes was last seen headed back to Holly Bay Marina on Laurel River Lake in southern Kentucky. He had been on the lake prior to a storm assisting a friend in securing their houseboat. Later that evening after the storm had passed, his pontoon boat was found against the shore of a mid-lake island, engine running in neutral. Local authorities began an intensive land and water search. Numerous agencies worked the lake for over a week, Clarence was not found. The family brought in several outside experts to search for Clarence. The family also performed an extensive search utilizing a drop camera. In early 2014 Mark Michaud of Southeast Louisiana Underwater Search and Recovery was contacted. In late 2015 Benthic Adventures began looking at the search in support of Mark and his efforts. Many Hundreds of hours were expended searching using side scan sonar and divers. Cadaver trained K9's were brought in and they located an area that is believed to contain human remains. Another volunteer was brought in to run scanning sonar searches and after 5 days of runs he had a viable target detected suspended in a tree in 160' of water. Numerous trips and many hours of diving have narrowed down the precise location of what is believed to be the resting place of Clarence Holmes. Early November 2016 we are going back on the water to narrow the search and locate and recover what we believe to be Clarence. This effort is non compensated and all divers and other personnel have to take time off work, many unpaid. The family bears the cost of providing food and lodging, a burden that has worn on them due to the duration of this search. All equipment is purchased or provided by the volunteer staff as are the breathing gas mixes that each diver provides for themselves. I will be attempting to update this story from the lake as time and connectivity permit.
Mountain View is the home of innovation. Right in our backyard, we have Google, Khan Academy, LinkedIn, and Synopsys, all encouraging nearby students to think outside the box and pursue their passions early on. It is not surprising then, that Mountain View’s 971 Robotics Team has a total of 70 high school members--a majority being freshmen. Having such a big team is wonderful in many ways. A lot of students interested in Engineering provides endless opportunities to inspire young scholars. Most importantly, it means we have innumerable amounts of great ideas circling around waiting to be discovered by their possessors. However, getting all those ideas out in the open can be difficult for some, especially when they are brand new to the team. In an effort to create a nourishing and connected community for prospective engineers, I hope to bring in an OpenROV kit and present the members with the objective of modifying the robot to help aid underwater exploration. The goal is simple but the reward is timeless.
5th graders in Louisiana must be able to describe local ecosystems. This expedition will give them a chance to view an ecosystem that is very common in our location. This will also help them determine how they can help/prevent our local ecosystems from washing away.
The past few months have been anything but dull - the ROV has kept us busy and amused! After a couple of issues finding acrylic cement (what seemed like a near impossible task in Ireland) and getting a glue gun from a teacher family member the ROV is up and running (named Stanley after a temperamental but water loving dog). We brought it out for testing in the Royal Canal last week and after a few minutes of swimming and doing all the right things we noticed a small bit of water in the electronics tube. It turns out we had a misplaced o-ring (always check your o-rings carefully before adding water to the mix). We discovered that rice sealed in a plastic container was a perfect desiccant for the electronics board, which got a bit wet during the flood. Our research expedition began yesterday with 36 hours or so of flights to the Philippines. The ROV was subject to much questioning (mostly from interested security guards) in Ireland and flew through customs in London Heathrow, Beijing, and Manilla airports - always good to know for your future travels as we were worried the lithium batteries might be an issue. The project is about to seriously get underway over the coming days as make it to our final destination - Marine Conservation Philippines in Zamboanguita - and with their help we will begin our research into the relatively unknown realm of mesophotic coral ecosystems. Stay tuned for some epic pictures and videos!
En Santa Rosalia, Baja California Sur construimos un OpenROV con ayuda de alumnos de Ing. Electromecanica del Instituto Tecnologico Superior De Mulege (ITESME) con la finalidad de explorar las profundidades del hermoso Mar de Cortes. In Santa Rosalia, Baja California Sur, we built an OpenROV with students of the Electromechanic Engineering Institute of Mulege (ITESME) to explore the depths of the beautiful Sea of Cortez.
The purpose of this expedition is to evaluate the BlueRobotics BlueROV kits and build dive setup and procedure for doing marine archeology/exploration with both a land based and boat based ROV topside station. Logistics are the biggest hang-up in small ROV expeditions and this 2-day adventure is set to develop the ConOps for marine work and kit evaluations for public dissemination. We also intend to collect CTD data (it's freshwater so not expecting mush on the salinity) and water samples for payload testing and fidelity datum points. We will publish all data and add videos as soon as they are collected. Depth – Maximum 62 feet (19m) Water Temp – Varies from 70 to 85 F (21 to 29 C) in the summer and 45 to 55 F (7 to 12 C) in the winter. There’s a stiff thermocline year-round and the water at depth is always quite cold. Visibility – Varies depending on number of divers Location – Rawlings, VA Dive Types – Freshwater, Shore, Wreck, Night
Hi Sorry for not updating for long time, but too much work and not enough hours... Here's a more complete picture of setup with the 320x240 touch display planned for the logger There's still room for much improvement on the amount of space not used. so plan in schrinking it as much as possible.
Here are the track logs from each day. The goal was to make progress north on day 3 and 4.

There's good news...actually, there's great news! Thanks to the OpenROV team and the Moore Foundation, I've been sent an OpenROV kit; it successfully navigated Indian customs and was delivered last month to me in New Delhi, India. If anyone else is trying to get an OpenROV kit delivered in India, feel free to get in touch if you need any advice. The kit itself is in a lovely white box well-packed in bubble wrap. It took pride of place in my workshop/utility room, and I began the actual build yesterday. I wasn't able to find acrylic cement in Delhi, so I've been using cyanoacrylate instead. This means that the see-through acrylic of the endcaps isn't quite see-through anymore, but they seem waterproof. I've made one major mistake so far; I put the non-pass through endcap together the wrong way around, but managed to separate it using a sharp tool before the superglue bonded completely. However, in the process I managed to cut first my thumb and then my little finger (I was in a hurry to separate the layers; superglue bonds within 20 seconds) so there's now blood visible inside the endcap layers...maybe it'll help attract sharks. Other than that, I'm really enjoying the build; once I get access to a soldering station and procure epoxy for the potting, it's only a few more hours till the OpenROV is ready for its first test!
There has been great coverage of the Return to the SS Tahoe expedition in the press. The first and biggest was a piece by John Markoff in the NYT: <a href="http://nyti.ms/29V96Ja" data-longurl="http%3A%2F%2Fnyti.ms%2F29V96Ja">nyti.ms/29V96Ja</a> Another piece, specific to the implications of small, affordable and powerful new ROVs on marine archaeology was on Capital Public Radio: <a href="http://bit.ly/29V8P8N" data-longurl="http%3A%2F%2Fbit.ly%2F29V8P8N">capradio.org/76574</a> Photo from Manyu Belani
We don't just use satellite tags to understand whale movements. Like our fingerprints, whales bear unique marks that enable you to individually identify them. Using photo-identification we can begin to understand how much time whales spend in an area, their distribution, monitor their health and even understand their social structure. But just amassing photos can make for a big problem with data management. It's also tough to collaborate with researchers around the world who could be seeing the very same whales we're seeing in Iceland. That's why, together with my pal Shane and the folks at Wildme, we made Flukebook. (www.flukebook.org) Flukebook is designed to be a tool to unite whale researchers together with citizen scientists. By fostering connections between an individual whale and person, flukebook can be a powerful conservation tool. At the same time, Flukebook enables researchers to leverage the latest in machine learning and computer vision to manage their massive catalogs of photo data. We're still fine tuning the site, but so far we have nearly 50,000 sightings across 10 countries! Why does this matter to me sitting on a boat in Iceland? Well, it's simple. It's cost prohibitive to tag every animal. By leveraging photos from whale watchers and scientists, we can begin understanding the paths these whales might take on their oceanic journeys. You can learn more about flukebook at <a href="http://bit.ly/2csBNPx" data-longurl="http%3A%2F%2Fbit.ly%2F2csBNPx">flukebook.org</a> and some of the tech we use at <a href="http://bit.ly/2csBtQN" data-longurl="http%3A%2F%2Fbit.ly%2F2csBtQN">wildme.org</a>
Success! My ROV is complete and AC Grebe (R 001) in the water. Things appeared to be A OK, no leaks that I could see. Motors all functional. I did notice it seemed to turn one direction better than the other. And I'm guessing i might need a little more weight. I also note that it would be much more intuitive to have a game controller. But I've not been able to successfully get a controller working as of yet. By hook or by crook I am aiming at the weekend of September the 18th for an actual in the water expedition. I have several offers of help, just need to scout a good spot and find the right time (aka tide). Hopefully in the meantime, I can figure out my controller issues.
SSWS is still active in Mid Puget Sound. Leather stars are prevalent (they are more resistant to the virus) and there are small sunflower stars but no medium or large. When small sunflowers reach a bit larger than hand size they seem to contract the disease and waste away as seen at the end of this video. The mystery six armed star makes another appearance :)
We are a small Elementary School with big dreams! We are passionate about discovering the area around us and developing strong questions to build a better understanding. The grade 5 class has explored major themes like our local nearby lake, creek, gardens and even chickens. This year the students will be diving into an ocean theme where they will develop and explore questions to learn about sea life, salinity, and much more. We are walking distance from an incredible underwater shelf full of anemones, cucumbers, seaweeds, and more. We are also walking distance from a lake which will provide great comparisons between salt water environments and freshwater environments. As a teacher it is my job to give students incredible opportunities to get excited about their learning. My objective with an ROV is to allow kids to go beyond the shoreline, get excited about the ocean, and help them develop their inquiry questions which will integrate into all the different subject areas. As the teams explore their inquiry they will use the ROV to help answer their questions and share their learning with other people in the school and the community. Check back to see where the exploration takes us!

"What happened with this expedition?" A number of people have asked me that recently. Quick answer: we missed the weather window last year. But we're still going! The goal now is to take one of the new OpenROV Tridents later this fall. It will be more robust and better able to deal with the conditions. Also, much easier to hike with.
With this 25m of buoyant cable, we can avoid snags. Huge thanks to Brian Gau and David Lang for getting us hooked up! Weather systems and currents should lighten up soon.
We aim to explore our nearby Montsweag Brook as an ongoing effort to understand our estuary's flora and fauna. We are developing a water quality monitoring program at our campus' waterfront in an effort to inform local aquaculture and adding the element of underwater exploration will only enhance these efforts.
We're still working on building the ROV. This is the kids first time using acrylic cement, epoxy, and soldering. They're having a blast learning about all the work and tools needed to build the OpenROV. Our planned launch date is either Aug 20 or August 27th. Here's a photo from our build.
11th and last day of our 2016 Lampedusa mission: releasing of several turtles in paradise. Early this morning, we all had a date on the beach of Cala Maluk. Daniela was there, of course, with all the volunteers of the Lampedusa Turtle Rescue center. The team from OCEAN71 was also ready with most of the gear: 360° camera systemunderwater wide-angle camera strapped on the back of a 27-kilo turtleunderwater photographer with housingassistance boatdroneThe plan was to release three fully rehabilitated turtles in one of the most picturesque beaches on the Italian island. At 8 o'clock in the morning, there were very few tourists interfering with their iPads, and the light was amazing. Have a look if you don't believe us: p.s. soon we will release the footage from the 360° camera system, and from the underwater wide-angle strapped to the turtle's back
Today was an amazing day! Seven kids joined us for electronics projects, minecraft, and of course the OpenROV build. It started out a little bumpy when we found out that the location we wanted to use wasn’t open until noon. It was a little challenging when the clubhouse wifi was down. But before we knew it, we were working on our first project making drums out of fruit with MakeyMakey. Then it was time to pull out the big guns. Yes, it’s ambitious goal. Give seven 10 to 12 year olds acrylic cement and let them glue together expensive, delicate, irreplaceable (at least by me) equipment. Yeah, I must be crazy. Maybe a love of Legos pays off after all. They pulled out instructions that were picture based, and pieced together plexi-glass pieces as if it were no big deal. My anxiety rose when we broke out the glue, asking myself “what do we do if they glue the pieces together wrong?” But they worked together like a team and carefully, and methodically pieced together their project with ease. Ok, a couple of my fingers may be semi permanently glued together (because I forgot my gloves). But they were inspiring. So this mommy isn’t going to lie, it was a little hair raising last night to think that I was getting ready to lead a gang of my son’s friends in a kick off meeting in STEM Camp. I had a dream last night that I was eaten by five dragons. But to my delight they were angels. We made some new friends like Mr. Steve who is a forensic science student. He’s agreed to support us on as a diver on our mission to the coral reef. Whew, now we can check that one off our list. Thanks Mr. Steve! Till next time, GO NINJAS!

A much needed update! The build has been a long and rewarding process! It has definitely been more of a learning process with more troubleshooting than I initially anticipated! Here is the build thus far, both the starboard and port motors are working and the battery tubes have been assembled! In the upcoming week I will be adding both the vertical and strafe motor and finishing the epoxy waterproofing! Hopefully we will be putting it in the water as well to test the seals so that in the next weeks we can start exploring! Thank you for following us on this journey! UPDATE: The OpenROV comes with 3 ESC's and is set up to run 3 motors with their 2.8 set up. To add a 4th Strafe thruster I had to add a 4th Afro12 ESC and then connect them directly to the DB25 pins TP23-TP25. It took me a bit of time to accomplish and lots of help from the OpenROV community forum boards. I need to still get the servo for the camera tilt, lights, and IMU sensor connected, hopefully in the next couple of weeks our first test dive can commence!
Our amazing trip was an incredible success! Every single one of the scouts that came on the trip had an experience of a lifetime! Throughout 4 dives, we collected some incredible footage and saw many things that we would never have seen without our OpenROV. Everyone was blown away by the incredible things that we were able to achieve with our ROV and can't wait to use it in many other places as soon as possible! There are many videos on our youtube channel now and there will be many more to come along with best of clips from our trip. (but that will have to wait for at least a week because troop 22 is now off the summer camp at the Rodney Scout Reservation in Maryland! We would like to thank OpenROV for all their support and hope that all of their employees enjoy the video we have taken. You can find our youtube at the following link; <a href="http://bit.ly/29YAsho" data-longurl="https%3A%2F%2Fwww.youtube.com%2Fchannel%2FUC-6cTEngnOol4GwWp_UONYQ">youtube.com/channel/UC-6cTEngnOol4GwWp_UONYQ</a>
Hi Explorers! This past weekend we took our finally completed OpenROV 2.8 for a free water dive at Three Mile Reef in the Gulf of Mexico. It was surprisingly a success! In conclusion, we saw stunning reef structure and fascinating fish, including the amazing Goliath Grouper! We put together some highlights! Enjoy! The EndeavourX team..
June 30 (CA): This was the day to visit the island of Mog Mog. Mog Mog sits at the ‘ crown’ of the Atoll, to the north and roughly in the middle of the arc that makes up the northern rim. From the men’ s house of Mog Mog, much of the Atoll can be seen, as can anyone coming or going. Mog Mog is the island of the Paramount Chief – they are responsible for guiding the Atoll, and in fact the neighboring islands out hundreds of miles into the Caroline Archipelago. It is the spiritual center, and carries considerable power, though in a very low-key way. Ruling in these islands is done with subtlety, not force. In fact knowledge is very much seen as power, and knowledge is accrued through listening, actions, and watching. Ironically, this is one of the problems these people face today. Young people are given knowledge only if and when they deserve it, and they deserve it by showing their desire to help and support their communities. Today, with the building of the outer island high schools in the 60s, the youth are shipped off for 9 months a year. This physical separation means they don’ t get as much of a chance to interact with their elders, and show they are worthy of knowledge. This limits the transfer of knowledge, or rather substitutes the transfer of traditional knowledge with that of school knowledge. In today’ s world, both are needed to hold the fabric of these societies together. When arriving to Mog Mog, lava lava’ s (the wrap-like skirt that women wear) must be donned and in place, men remove their shirts (women usually too if they are from the Atoll), and everyone removes any hats. No one stands up in the boat, and the boat has to come in at an oblique angle – best seen from the men’ s house. Not observing these would be a sign of disrespect. Historically, the arrival direction was important as it signaled the arrival of a canoe with a sea turtle that has been harvested. Sea turtles must be taken to Mog Mog for blessing by the Chief there before distributing to other islands (this is not being observed much any more). This, and many other customs, were really conservation and management measures, as they limited the take of large slow growing animals such as turtles. The people of Mog Mog are among the most welcoming in the Atoll. Although reserved, they are generous, thoughtful, and, honestly, wise. Earlier this summer they held their 8th grade graduation-a BIG deal on these islands. They had heard that Nicole and Giacomo’ s son Alessio (who was with them on the first science team), had not been able to attend his 8th grade graduation to be able to come to Ulithi. They came forward and invited Alessio to their graduation, and gave him a fantastic middle school exit ceremony!Alessio in his graduation get-up. Thanks Mog Mog!! The waters of Mog Mog are not as deep as Falalop or Asor Metalioch. The water in the front of the island drops gradually down to a sandy bottom, then more reef, then more sand as it descends into the lagoon. The OpenROV continues to perform well, allowing for exploration into waters we have not seen yet. Currents buffet it a bit, and we aren’ t able to get it into the areas of strong current, but for the calmer sites it is working! There are many exciting places to explore in the lagoon. The Naval 3rd fleet left plenty behind to look for, including some landing craft at Asor, and a munitions dumping site somewhere near Mog Mog. Ulithi Atoll was also the site of one of the only successful Japanese Kaiten attacks (a suicide torpedo – the water version of the kamikaze planes). Michael Mair wrote a great book about it: “Oil, Fire and Fate, the Sinking of the USS Mississinewa”. She lies with her massive rear propeller at about 85 feet in the lagoon. The BRUVs, in their search for fish, are also working well. We will all have to stand by to see the results!!

This beach clean-up( august 21st 2016) is to mainly clean-up the earth and also promote our next clean-up at crystal springs in Dunnellon FL. ( TBA ) with the open ROV's 2.8 that the GURC built in 3 days!!! we would like to build water testers and clampers to clean the river of pollution and also test for pollution. we would love if we can gather more open ROV pilots to create more of a progress to clean the crystal river springs. so in the beach clean up we need funding for food for the amazing volunteers and the supplies that we need to clean the beach. with the funds that we produce out of the beach clean-up 30% will go to the animals at the Clearwater Marine Aquarium and the other 70% will go to the crystal river springs so we need all the help we can get please & and thank you!!! Who are we? We are a group of girls inspired individuals interested in STEM subjects hoping to make the waters of Florida cleaner. We all attended Girl's Underwater Robot camp sponsored by National Geographic, CTAE, Pinellas County School's STEM academies, and Clearwater Marine Aquarium. At this camp we constructed three ROVs that we will be using for expeditions. You may get wet, so be prepared for that. Bring shoes you can walk in comfortably and would be okay with getting wet. Wear and bring sunscreen, as well as a hat and sunglasses. It may rain so bring a jacket and/or umbrella. Bring lots of water! Bring snacks, lunch will be provided. On Crystal River, we will be renting a pontoon boat. It will cost between $150 and $200 to rent a 12 person pontoon boat for the day. Catering for the event will cost around $100. Crystal River contains many springs of varying depths, the deepest being around 15 meters.
Friday, June 10th ESC OpenROV Intern: Kim Ha "Today was the first time ESC's OpenROV was placed in the ocean and things went fairly well for a first trial. The water was a little rough today so Nessie had a little bit of a struggle getting far in the ocean. However, she still got a good distance away from the shore and into the water. It's a little difficult to see what's in the water even with Nessie's lights on full brightness due to murkiness of the water. An issue that we kept running into was seaweed collecting on Nessie which created drag and jammed her propellers. However, she stayed connected and working the whole time making this trial successful."
Here is a sample video clip from the cockpit of the LFROV shooting a lionfish sponge in the pool during testing. A superstructure for the LFROV was built to hold the weight of the mechanism as well as the buoyancy required as not to place any large forces on the OpenROV itself. The mechanism was designed to be modular in order to be easily added and removed from the OpenROV. Communication to the mechanism electronics was accomplished by using bluetooth so that no control or power cables needed to be interfaced to the OpenROV.
First sea AKA Lake trials were succesfull! Next step will be to pack up the Open ROV and head back over to Myanmar to get going on those Coral reefs and work towards long lasting protection of a yet undisturbed underwater wildlife.
