The Defense Advanced Research Projects Agency’s Robotics Challenge teams using DARPA’s Atlas robot, developed by Boston Dynamics, met in Waltham, Mass., in January to learn about upgrades to the robot. It was redesigned with the goal of improving power efficiency to better support battery operation. About 75 percent of the robot was rebuilt. Only the lower legs and feet were carried over from the original design. Lighter materials allowed for inclusion of a battery and a new pump system with only a modest increase in overall weight. The upgraded robot is 6-foot-2 inches tall and weighs 345 pounds. DARPA image courtesy of Worcester Polytechnic Institute
