These swimming robots are often referred to as maritime or marine robots, aquatic robots, remotely operated vehicles and autonomous surface water (or underwater) vehicles. I’m interested in swimming robots for the same reason I’m interested in flying and driving robots: they allow us to collect data, transport cargo and take samples in more efficient and productive ways. Flying Robots, for example, can be used to transport essential vaccines and medicines. They can also collect data by taking pictures to support precision agriculture and they can take air samples to test for pollution. The equivalent is true for swimming and diving robots.
So I’d like to introduce you to this cast of characters and will then elaborate on how they can and have been used to make a difference. Do please let me know if I’m missing any major ones—robots and use-cases.
This tethered diving robot can reach depths of up to 100 meters with a maximum speed of 2 meters per second (7 km/hour). The Trident has a maximum run-time of 3 hours, weighs just under 3 kg and easily fits in a backpack. It comes with a 25 meter tether (although longer tethers are also available). The robot, which relays a live video feed back to the surface, can be programmed to swim in long straight lines (transects) over a given area to generate a continuous map of the seafloor. The OpenROV software is open source. More here.
