Tokyo Institute of Technology's SOINN robot teaches itself to serve humans (video)

Robots have been replacing more and more human workers for quite some time now, but in most instances they're still just being programmed to perform specific tasks. As evidenced by this bot developed by the Hasegawa Group at the Tokyo Institute of Technology, however, there's also a growing number capable of teaching themselves some new tricks, and they're getting smarter every day. This particular one employs what's called a self-organizing incremental neural network (or SOINN), which lets it build up a base of knowledge that it can apply to new tasks and make educated guesses about how to proceed with them -- in this case, pouring a glass of water and then dropping an ice cube in it (or what's supposed to be water and an ice cube, at least). Head on past the break for a video.

Treebot climbs trees, is a robot (video)

Remember when you didn't consider climbing trees a chore? Treebot doesn't -- but then, it wasn't programmed to know boredom. The robot was designed by a team at The Chinese University of Hong Kong for the express purpose of shimmying up trees autonomously, figuring out the best route up a trunk using built-in touch sensors. The 'bot's body is designed like an inchworm, expanding and contracting as it works it way up -- unlike other climbers we've seen. Treebot can carry up to 3.7 pounds as it inches along, opening up the possibility of using the machine to prune hard to reach leaves. It can also shuffle up a variety of different plants, including bamboo stems, as evidenced by the sped-up video after the break. Unwieldy foliage, you've been put on notice.
