A Wired News article and a San Francisco Gate article offer photos and descriptions of experimental robots that have been under development for several years at the Autonomy and Robotics group of the NASA Ames Research Center. Among the robots designed to test ideas for planetary exploration are the K9 rover (more K9 photos, 2003 K9 Field test photos), the 8-legged Scorpion (another NASA article on the Scorpion), and the 12 segment Snakebot (more Snakebot photos).
