A very entertaining and enlightening place to browse. The friendly folks at M.I.T. are at it again. Using computer and robotic technology they have built a robot to better understand and emulate human intelligence. Their humanoid robot Cog tries to approximate the sensory and motor dynamics of a human body. Except for legs and a flexible spine, the major degrees of motor freedom in the trunk, head, and arms are all there.
Sight exists, in the form of video cameras.
Hearing and touch are on the drawing board. Hands are being built and a system for vocalization is also in the works. Watch Cog change and grow as the research progresses. If your computer finds proof of alien life, then you'll be credited as a co-discoverer. You can also form teams, compete with others, look at star maps of the areas scanned, and much more.
