By far the most interesting robot I saw was the RoboTuna, which looks eerily fishlike (no gills). The tuna (the real one) is known to be able to travel long distances, which led scientists to believe that tuna must use their energy efficiently, which led some crazy geeks to try and replicate the tuna’s efficiences in a robot. I wish they have the video of RoboTuna online, it was amazing to watch.
Some other interesting projects at MIT that I didn’t see at the Museum:
Robot Pike (video!!!)
W3C: Who knew that the W3C is an MIT Research Center?
