As part of the Massachusetts Institute of Technology's Artificial Intelligence Laboratory, this is is a well-planned Web site devoted to the research and development of Cog, a humanoid robot. Combining robot mechanics with artificial intelligence, Cog is the closest thing yet to Star Wars's C3PO. Highlights of the site include an in-depth research section with links to papers on relevant topics (PostScript, .pdf); downloadable publications including theses, tech reports, and symposium papers (.pdf, .ftp, PostScript, gzipped); and finally, a high-resolution video library with discussions and demonstrations of Cog (QuickTime, RealPlayer, and MPEG). This detailed site will be fascinating for humanoid robotics enthusiasts as well as for researchers and educators in robotics and related fields.
