From 1998 to 2001 I was a research professor at the Robotics Institute of CMU. I worked with Professor Manuela Veloso on multi-agent robot teams. I lead the design and programming of the Hammerheads robot soccer team (left) with lots of help from Rosemary Emery, Ashley Stroupe, and Steve Stancliff. We investigated a number of interesting topics with these robots including collaborative localization, behavior-based pushing, and cooperation protocols.
