Not too surprising, but the minutia of the build is proving less interesting to the kids. However, to their credit, they remain at the table and find something interesting in each step. This video shows an example-- there is subtly so I recommend full screen and sound. https://youtu.be/qoysBJrdpDQ
Here's an example of what we can create using UAV-generated orthophotos. This is a digital elevation model of one of the archaeological sites that we've already found. It was done by our UAV wizard, Larkin Carey of Falkor Aerials using a DJI Phantom and DroneDeploy's software. We're hoping to produce DEM's for every one of the structures we find so that our archaeological team can more easily study them when we're out of the field. This tool also saves valuable time when we are working in such a large area and at elevations that make it difficult to cover ground quickly. Larkin reports that the altitude does make flying a bit more difficult and it really chews through batteries!
The Anchovy is a simple, long range, deep sea R.O.V. costing (hopefully) under 200 dollars to make and build. It consits of a single piece of pvc with two end caps, 2 motors, a livestream video camera, a gopro, a ballast, some floodlight leds and a thether atached to a buey housing the rf module. Later versions may include depth sensors, gas sensors and other added electronics. Keep in mind this is all in the development stage so feel free to contact me with any questions or ideas at firstname.lastname@example.org
Having updated the firmware, I was totally expecting my initial powering on of my OpenROV 2.8 to be only 75% functional based on my lack of experience with acrylic bonding and soldering. I was elated when Ioaded that batteries after assembly and it lit up! I was even able to connect to the cockpit with very little trouble as well having had some experience with IP networking. The only issues I noticed at first was that I had installed the camera upside down (the forum advised simply removing it and flipping around which was not too hard) and the starboard LED lights are dimmer on one side. I suspect my rookie soldering to be the root cause and I will look at this later. For a test run, I put the ROV in a 300 gallon hot tub (unheated) and was amazed that it flew as expected. It soon became apparent that my piloting skills will need some honing.
Back at the lab, been doing work troubleshooting my engines... One of my engines wasn't working right. Support suggested I update all the software and firmware and all that goodness in case there was something buggy. For good measure, I ordered some new engines along with SD card with the latest and greatest. The update process was less fraught than I expected, and I had the ROV back up and running pretty quickly. But alas it was to no avail, so I began the slightly tricker task of replacing the motor. In stripping wires, I managed to to rip one wire off of one engine -- luckily the order comes with a couple to spare. I much more carefully stripped the wires down and set up to solder the engine on. The starboard engine has the shortest wires, so the least slack to work with. Which was problematic because with my now rusty soldering skills, I managed to blow it on one connection (soldering quickly on those wires is important, because it's easy to overheat the wires and melt the plastic sheathing -- or, as it turned out in my case, one end of the plastic shrink tube that was to protect the connection). But it's on and back in place. And to my relief, the engine sounds more or less the same as the other -- so hopefully I'll be running in straight lines from here on out. I still can't tell why the original motor was bad. It doesn't appear to have any defects or anything stuck inside, so who knows. Now, I just need the rain to clear up a bit -- and I'll be out on the lake.
Looking at plants Continuing on the trek, we were able to look at some frozen plants! We believe these would be the lower stalks of cattails. Although it is rather ordinary, what we find exciting here is that we're able to look at this, a distance away from the coastline, with the robot. It's a prime opportunity to use this technique to see what else we can find.
It's time for another, much-delayed update; in the last one, I talked about how I received and unpacked the OpenROV, and began putting it together. I used cyanoacrylate instead of acrylic cement to stick everything together, which worked well, and expected only a few more hours of work before the OpenROV was complete. What I hadn't bargained for was how much time it would take for me to identify and procure the correct type of epoxy for the various bits of electronic potting required. Since I'm based in India, I wasn't able to get the epoxy, with mixing syringe, recommended in the OpenROV build. The epoxy I have used in the past (brandname: Araldite), primarily for woodworking purposes, is far too viscous to be pushed into the OpenROV's empty spaces, and I was bit lost as to how to proceed. I put the build on hold for a while, but continued looking for suitable epoxy resins. I contacted a few chemical suppliers in India, and while they claimed to have low-viscosity epoxies available, they were only willing to sell them in very high volumes. Finally, I found some clear-casting epoxy resin on Amazon India (name: MurtiSil - Easy Cast 33 - Transparent Epoxy Resin - 911133000750 - 750 Grams) which seemed to be what I was looking for. There wasn't much documentation available, but since the seller's description states that this epoxy has "very less viscosity like water", I decided to take a chance. I'm glad to say that this epoxy worked like a charm; it did flow like water, and I used a set of 20mm medical syringes to measure, mix and inject the epoxy into the OpenROV. In the meantime, I also quit my day job at WWF-India to focus on using technology for wildlife (techforwildlife.com), and allocated 3 days of my first week off work towards OpenROV construction. While there were a few issues, I managed to work them out using the very helpful OpenROV forums, and In brief, I put the OpenROV together, put the batteries in and activated the device. And it worked! At this point (30th January 2017), I have a nearly-complete OpenROV; the only task left is to ensure that the main electronics tube and the soldered connections are waterproof, and then we can begin our first test dives.
Getting ready to do some drone reconnaissance (droconnaissance!) this weekend. Here is a pro tip for everyone: Scratch that....Here is more of a weekend warrior tip for everyone: If you're going to be fly an aircraft (and that does include drones or UASs as they are officially known), you should always double check if there is a temporary flight restriction (TFR) or NOTAM in the area you will be operating. I use SkyVector.com for checking these kinds of things. It'll take you two seconds, and save you a heap of trouble if you happen to fly into a restricted area. Also, take a second and make notes of any small airstrips near the area you plan on flying. There are a lot of private grass strips out there that many people don't know about! That is enough PSAs for the day. I'll be shooting the Mavic up on Saturday to do a little scouting. The lake is much higher than the last time I was out to the Pickwick site, so it is definitely going to be a little tougher to orient myself. Purpose #2 for the scouting is to determine what kind of water clarity we'll have for the dive. We picked up another deluge of rain over the weekend, so I'm hoping the turbidity hasn't increased too much. Here's to clear skies and light winds for the weekend!
It's about time! If you didn't want to sit through hours of raw dive footage, here's the highlight video from our incredible adventure.
Its looking like it will now be the Greek Island of Milos, looking at the hydrothermal vent systems. The Venting sites SE of Fyriplaka volcano as well as in Adamas Bay - Airport (1-2 m depth) and Cape Boubarda (60-110 m depth), Palaeochori Bay (0-40 m depth), east of Spathi Point (90-220 m depth), Voudia Bay (10-30 m depth); The hydrothermal discharge (123°C) off shores of volcano with precipitates of Fe oxides, amorphous silica, and native sulfur. "Milos (Hellenic Arc) can be regarded as having 5 separated vent fields: 1. Milos Bay (the central cauldera), 2. N. of the island at the cauldera entrance, 3. Boudia Bay (NE side of island), 4. East of Island (NE of Spathi Point), 5. SE of Island (Palaeochori Bay-Kiriaki Bay)".(Dando PR, et al 1995).
Our time in a Brazil with a fantastic group of students ended about a year ago, but we've been busy evaluating the program, improving the curriculum, and finding ways to tell the kids' stories. The highlights: 1) Our partners at USC's Rossier School of Education conducted an analysis of students' pre- and post-tests to show statistically significant educational gains following the Mars Academy program. Not only did the students learn about the scientific process, the ocean, and outer space, but they also demonstrated a greater sense of purpose and agency in improving their communities through science. 2) Hank and our film team have been hard at work on a feature-length documentary. Check out the extended trailer below! 3) We're planning future Mars Academy experiences for children around the world, so stay tuned for our next journey of exploratory education!
An interesting note. We've discovered that there is a Geocache hidden in the depths of the Lake that, until now, only certified scuba divers have been able to locate. Though we are divers as well, I am pretty sure no one has done geocaching with an ROV before. This is now an exploration target after we've checkout out our gear. From Blue Octopus Scuba: http://www.blueoctopusscuba.com/local/lake-phoenix** **"Certified Divers headed to Lake Phoenix for fun or skills practice should stop by the Admissions Desk and obtain a laminated map of the lake. There is a hidden underwater Geo Cache only reachable with SCUBA equipment, if you can find it. You'll have to plan your dives carefully to reach the Geo Cache and the mystery item..." One thing we didn't design for was salvage. Looks like we may have to rig up a gripper of some kind. Cache #GC2VPD7 From the geocaching.com: Geocache Description: "You must be a certified scuba diver to seek this cache located at Lake Rawlings Quarry in Rawlings, Va. Check in at the quarry. The cache is located at of the Mystery Boat (#11 on the quarry map). The site is not marked by a buoy so it is recommended to reference the map. The cache is a plastic box with DAN stickers on it. When you find the cache, sign the log secured to the top of the inside of the box. Take one of the FTF prizes and leave another trinket for future cache seekers. After you have found this cache, send us a photo of you with it and tell us the story of your adventure! " N 36° 56.984 W 077° 46.003 UTM: 18S E 253639 N 4092873** This is great fun. It also happens to be near the Blast Hole Whatever that is...We will find out!
The past month has been full of excitement. We have been scouring the coast for mesophotic coral ecosystems and have been successful. Explore and you will find! The most exciting element of our study is the prospect of researching and exploring depths that have been seen by a privileged few or no one at all. We were told that there wouldn't be much beyond 30 m here in the Philippines, but we now know that this is incorrect as the coral reefs continue beyond diving limits and tend to be intact and healthier the deeper one explores. Monstrous gorgonians continue to take our breath away. Our wifi connection is very limited here making it difficult to upload pictures (let alone videos), but we hope to upload more pictures of these beautiful environments so you may be able to see the richness we are experiencing every day thanks to OpenROV.
Here's the screenview video that Ingmar captured January 2nd from the cockpit. Cool to watch the controls as it maneuvers and navigates. I think we can ROV around the sculpture, Zoe, and through the reef balls (the cement orbs with holes in them) if we replace all the cable with the buoyant one. Next on our list is to find how and where to get some. Is it here in Mexico?
After a night of discussing forecasts, the collective group of pilots decided to attempt a Hike and Fly of Mt Tamalpais. At 7:15AM I was surprised by frost on my car and had to scrape it off!! in Mt View. I hope people covered their plants! Sail Tactics puts out a 1:00AM 2 day wind forecast and a 7:45AM day of which is ultra-high res at 200meters. The 1:00AM looked like there would be a flyable window from 9AM-2:30PM. I picked up Jon and headed to the Fire Station at Stinson Beach. As Pilots we have to sign in at Pan Toll Station first. Crossing the golden gate the observations matched the predictions with a less 5 knots to Light/Variable. Mt Tam. Offers views of the Farralon Islands, Point Reyes, Pacifica, and the Interior Bay including San Francisco, Angel Island and Mt Diablo. Basically the whole Bay! Over the last week the Area was impacted by a number of Storms, bringing rain and wind. Typically in the days following storms the air mass in unstable and flying conditions can be very good. Free Flight Lab is interested in capturing conservation data of the Lagoon. I plan to monitor and detect any possible Algae blooms and observe changes in the land due to tidal changes. Looking at the new forecast it seemed like the flyable window got shorter and the new wind came in sooner and stronger then the 2-day. The hike is beautiful. At Launch you could see some breeze start to spill over the point and fill in along Stinson beach. I believe in the forecast so I was prepared to Launch. As my friends made fun of my habit to launch early I saw birds and could feel the air. It was about to be time. I took off and was able to soar the faces near launch in the fresh breeze. The breath from the mountain changed and it was time to move on. I aimed for the next ridge, sunny faces, steep terrain, looking for shadows because on the hike we saw that the grass was still covered in frost. Thermal Gradients make for good thermal triggers. I was tricked into turning in a little bubble and the gains did not match the losses. Time to leave the ridge. At this point this line can be nerve racking, I chose to attempt to hook a thermal and now had to glide efficiently over the trees to the next ridge. I made it easily, but... without local knowledge it looks like there is no good way out if you get too low. Actually there is, but it not a great option. It would probably be fine, but not worth taking chances. Arriving at the Main Ridge I worked light bubbles along the shadow lines and tree lines.. Alternating sides as the mountain breathed. Finally at the last moment before pushing out to the beach... I hooked one, not a bubble but a nice continuous source of lift. Coring it to ~2600ft I was able to see the whole bay area. I flew over to where I launched, said Hi then proceeded to play in the sky with friends both hawks and pilots until my fingers froze! I took a flight path north to investigate the Lagoon. Floating along lifty lines I flew over coastal highway 1. For an hour I took to the skies flying on invisible elevators, and after landing on the beach I went up for seconds, this time as a Tandem Passenger to help a friend train, and look at the possibilities of flying passengers and equipment for Free Flight Lab. What a great day exploring a local Microclimate. We Flew from 11AM-2:30pm It ended up being a bit of a blend of both forecasts. The transitions and timing were spot on. Tomorrow Windy Hill.
My name is Jake Adams, a lifelong explorer of the marine environment, self taught and with a Bachelors in Marine Science. For the past decade I have been writing and reporting on all aspects of little traveled places. I am a coral 'expert', and everywhere I go I usually find new and unusual corals, photograph and document them for popular and academic audiences alike. I have been dreaming of going to Palau for my whole life, and next year I finally have the opportunity to visit this ecoregion at the mostcritical time. Each year, the January full moon is a time for many different species of iconic reef fish to gather in huge schools to participate in mass spawning events. I think this is an amazing opportunity to document this event from a unique perspective, and perhaps even document some unexpected behavior and animals with an OpenROV. Everywhere I go I stay with the people, the local communities who live near the marine environment and help them to develop sustainable forms of income, my favorite projects include consulting on coral farming efforts for reef restoration.
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 !!!
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.
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.
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.
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.
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: nyti.ms/29V96Ja Another piece, specific to the implications of small, affordable and powerful new ROVs on marine archaeology was on Capital Public Radio: capradio.org/76574 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 flukebook.org and some of the tech we use at wildme.org
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.
