Networks of robotic fish that can glide long distances, as well as swim by flapping their tails, are being developed by Michigan State University researchers to explore the Gulf looking for spilled crude oil. (Source: G.L. Kohuth)
Actually, the Wave Gliders' propulsion system mechanically converts wave motion into forward movement, but their instruments are powered by solar energy. So I thought you might have them in mind when making the comment about these robotic fish and energy-harvesting.
Ah yes, the wave gliders run on solar power, I think...and keep themselves afloat in this way. Well at least the energy can be used for the robot itself, which is pretty good. And then if memory serves I believe someone even designed a recharging station in the sea where the gliders can repower. Imagine all of these fishy robots swimming around doing their job in the ocean and then stopping off at the recharge station to refuel by charging up! I don't think the idea is so far fetched.
Elizabeth, that would make a lot of sense. I bet you're thinking of the Wave Glider design, which does exactly that. The energy harvested from such designs is usually only enough to help keep it going, not enough to power much else, unless combined with solar panels.
Those are definitely two of the most interesting things about this robot for sure, Ann. The glide mode is especially interesting. I wonder if there could be an energy harvesting option in which the robot can harvest energy from its own movement?
Aside from the fact that this robot may be able to help clean up oil spills, a worthy cause, I especially liked the fact that it combines two different types of movement to help it navigate through different conditions of water and obstacles in water. That's not intuitively obvious and also not trivial from a mechanical design standpoint.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
