CMU's team was one of the few that attempted all 8 tasks during practice. But then, their robot, CHIMP, is an outlier. The 5-foot-tall, primate inspired bot has legs, but it doesn't walk, instead rolling on tracks embedded in its shins and forearms. When it appears to be stand, it's really kneeling, and is therefore rarely in danger of falling. Other bots, like NASA's RoboSimian and the University of Bronn's Team TimbRo, also use wheels, crawling, or a combination of both as an alternative to two-legged mobility. That inherent stability let CMU's team hold nothing back, and post the second-best practice run, while gaining experience with the entire course. CHIMP competes in today's final heat, while RoboSimian and NimbRo—a team with little funding, and zero buzz coming into the finals—will be in the next-to-last group.
