Team IHMC's Lessons Learned from the DARPA Robotics Challenge Trials

AbstractThis article is a summary of the experiences of the Florida Institute for Human & Machine Cognition IHMC team during the DARPA Robotics Challenge DRC Trials. The primary goal of the DRC is to develop robots capable of assisting humans in responding to natural and manmade disasters. The robots are expected to use standard tools and equipment to accomplish the mission. The DRC Trials consisted of eight different challenges that tested robot mobility, manipulation, and control under degraded communications and time constraints. Team IHMC competed using the Atlas humanoid robot made by Boston Dynamics. We competed against 16 international teams and placed second in the competition. This article discusses the challenges we faced in transitioning from simulation to hardware. It also discusses the lessons learned both during the competition and in the months of preparation leading up to it. The lessons address the value of reliable hardware and solid software practices. They also cover effective approaches to bipedal walking and designing for human-robot teamwork. Lastly, the lessons present a philosophical discussion about choices related to designing robotic systems.
