BigDog is developed to function as a mechanical mule. The powered autonomous quadruped is capable of carrying significant payloads, operating outdoors, with static and dynamic mobility, and has fully integrated sensing and navigation.
Sensors for locomotion include joint position, joint force, ground contact, ground load, a gyroscope, LIDAR, and a stereo vision system. Other sensors focus on the internal state of BigDog, monitoring the hydraulic pressure, oil temperature, engine functions, battery charge, and others.
BigDog runs at 10 kmh, climbs slopes up to 35 degrees, walks across rubble, climbs muddy hiking trails, walks in snow and water, and carries up to 150kg loads.
