http://www.asirobots.com The Chaos High Mobility Robot is more capable than ever, with hot-swappable internal battery/payload bays and the ability to carry over 100 lbs. Battery life is at least four hours, with the upper limit and range not yet determined. As a platform, Chaos will work with almost any payload or arm, and can accept alternate power sources and radio solutions, as well. (This video shows the arm ASI designed for the previous Chaos design bolted onto an improvised rack with an external battery.) Tracks can now be adjusted and changed without the use of tools. Chaos is currently being used for several military functions as well as underground mining operations.
