MIT Robot Walks On Water

An anonymous reader writes "Researchers at MIT have solved the mystery of how water striders propel themselves across water surfaces and in the process have created a robot called Robostrider that mimics the behavior. With cool stuff like this, it's no wonder MIT is number one in engineering."

    Actually there are several people who thing that MIT's direction in AI has gone seriously awry. Marvin Minsky (though somewhat stodgy), has pointed out that MIT's focus in robotics is no longer on figuring out how to make things that do stuff for people, but on subhuman gadgets.

    So, yeah they may be number one, but in a way, they've let down the old guard of AI researchers.

    Still, this is quite cool.

      problem is, minsky spends too much time debunking good theory than creating new ones. let's take an example. minsky proved that 2-layer neural networks were not capable of generalizing to many tasks. the proof is indeed notable, but then came *gasp* three layer neural networks, and minsky's point was irrelevant. i think he is just pissed that his ideas were mostly abandoned by AI researchers.

    Yes, this particular research project is very cool.

    However, since it was mentioned in the original post, I will say that USN&WR's rankings are flawed, and do not necessarily reflect the quality of research taking place at a particular institution. In fact, a significant portion of their rankings are based on name recognition alone, which has nothing to do with quality of research.

    The question is about propulsion, not weight-to-surface tension ratios sufficient for flotation. This research gives a better explanation of the mechanism by which the water skimmers move with such great efficiency (namely by created subsurface vortices with their middle pair of legs) and puts to rest the notion that it is attributable to the waves themselves created by a rowing action.
