An autonomous, rugged, and modular search-and-rescue robot built on open hardware. Rather than overspecializing, the robot combines multiple capabilities into a single adaptable platform. Unlike conventional tracked robots, which have a relatively rigid footprint, Athena’s tracks are attached to four independently controlled flipper arms. On flat surfaces, the arms remain tucked in, and the robot moves like a normal tracked robot. However, each arm can rotate and reposition itself, allowing the robot to reconfigure its overall shape in response to the terrain.
