University of Southern California reported on their progress with polymorphic robots at 2007 Space Technology and Applications International Forum. Summaries of the report can be found in an Astrobiology Magazine story and a Yahoo! News article. The Superbots are autonomous polymorphic robot modules that can assemble themselves into various shapes and reconfigure into other shapes as required. Think of it as autonomous LEGOs. The researchers prepared a large number of videos of the Superbot modules configuring themselves into various shapes such as humanoid robots, four legged walkers, snake robots, and other shapes. Additional videos can be seen in the Astrobiology story (some of the videos are in a proprietary MS format and may not be viewable in all browsers).
