The venerable Gamma series plays chess against the up-and-coming Delta series at AAAI 2010 in Atlanta Georgia.
This was part of the Small Scale Manipulation challenge, in which a variety of different robots competed to play chess. The key to this competition was not the chess itself (IBM has already done a fine job with that issue), but to actually move the pieces around the board, promoting development smaller, cheaper robots which still provide interesting functionality.
Our entry demonstrates a number of features from the Tekkotsu robotics framework, including locomotion, localization, path planning, computer vision, and grasping.
Jonathan Coens (shown in video) did the majority of the development work, with support from Ethan Tira-Thompson and our faculty advisor David Touretzky.
