A large number of robots have been designed to operate in or near water, whether fresh water or the salty seas. Military, homeland security, and naval operations are some of the more obvious application areas. For example, Bluefin Robotics' autonomous underwater vehicles and the Hawkes Remotes remotely-operated vehicles are designed for reconnaissance, surveillance, and detecting unexploded ordnance. Like many of their unmanned ground vehicle counterparts, they can go where humans can't.
These, and other mostly autonomous robots are also aimed at scientific exploration and data gathering, as well as maintenance of ships, oil and gas pipelines, telecommunications cables, or alternative offshore energy installations. Some target water or environmental health monitoring.

Festo's AquaPenguin is one of many projects the company has pursued under its Bionic Learning Network. The network's purpose is to use the energy-efficient principles already found in nature and adapt them to automation technology. The AquaPenguin is an autonomous underwater vehicle with penguin-inspired hydrodynamic body contours. Equipped with a 3D sonar system, like that of dolphins, it can communicate with its surroundings and other AquaPenguins, independently orient itself, and navigate. Its torso, head, and tail sections can move in all directions for maneuvering in cramped areas, letting it turn on a dime and swim backwards. (Source: Festo)
Further down the scale are the awimming pool cleaning robots which sweep and vacuum the bottom of your swimming pool (if you're lucky enough to have one...). Designing a robot that can work underwater is not trivial - getting rid of excess heat is a problem, you can't expose a heatsink to the water because it will suffer galvanic corrosion. Keeping water out is another problem, when you have moving or rotating parts passing through a watertight enclosure.
Ann, it would be wonderful to see the military engage in formal tech transfer programs like the national labs do. The labs have programs to send their R&D out to start-ups -- usually start-ups runs by former lab researchers. It's a great idea to make the taxpayer-financed research available to entrepreneurs. Robotics looks like a perfect candidate for tech transfer.
Chuck, I agree--they look so vulnerable, yet are surprisingly rugged. In fact, Liquid Robotics has just formed a separate joint venture company with Schlumberger for oil & gas exploration and production services: http://liquidr.com/files/2012/06/Schlumberger_LiquidRobotics_Joint_Venture.pdf
Beth. when I looked at the details--as much as Festo will give--of their jellyfish and penguin robots I was stunned at the quality of the design. Perhaps I shouldn't have been: Festo is known for quality and clearly good design is required for underwater robots, especially autonomous ones. Their utility, at least for surveillance-type apps, seems pretty clear.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
