System description

SPOT is based on the design of the ARAMIES robot. It is a fully functional ambulating robot that is robust and kinematically flexible  four-legged walking robot, having a total of 28 joints. Each leg has six degrees of freedom, which allows the robot not only to walk over diverse terrains, but also to manipulate objects. A hip joint allows the robot to bend at the waist in order to sit on its hind-legs or to climb steep slopes.

Besides these kinematic abilities, the robot also possesses a rich repertoire of sensorimotor capabilities. It is equipped with a head-mounted stereo-camera in order to sense visual depth information. Furthermore, there are infrared sensors and pressure-sensors on each leg. The robot also makes use of a laser range-finder, motor-current sensors, ultrasonic sensors, gyroscopes, and accelerometers.
