We've seen a number of options for controlling real worms, but never a worm robot, until now. Enter Meshworm, the latest creation from researchers at MIT, Harvard University and Seoul National University. The bot is made from "artificial muscle" composed of a flexible mesh tube segmented by loops of nickel / titanium wire. The wire contracts and squeezes the tube when heated by a flowing current, but cut the power and it returns to its original shape, creating propulsion in a similar way to its living kin. Taking traditional moving parts out of the equation also makes it pretty hardy, as proven by extensive testing (read: hitting it with a hammer). DARPA is known for getting its fingers in all sorts of strange pies, and it also supported this project. We can't see it being the fastest way of gathering intel, but the potential medical applications, such as next-gen endoscopes, sound plausible enough. Full impact tests in the video after the break.

A team of researchers at South Korea's Seoul National University have been busy developing biologically-inspired electronic skin that is capable of "feeling" subtle stimulus such as bouncing water droplets and human heartbeats. The skin's surface is covered in two interlocked arrays of 50-nanometre-wide polymeric nanofibres that act like hairs on the surface of the skin, coming in contact with one another under the strain of external force. That contact then generates a current to help the skin gauge the changes in pressure, according to New Scientist. The creators of the flexible skin say that sensor response can be repeated up to 10,000 cycles, displaying their output on a computer in real-time.
Electronic skin lets machines sense water droplets and heartbeats, wonder why they were programmed to feel originally appeared on Engadget on Thu, 02 Aug 2012 04:21:00 EDT. Please see our terms for use of feeds.
