THE AI ANGLE

Training energy-efficient locomotion policies in simulation

Researchers built a quadruped robot that completed a 26.2-mile marathon on a single battery charge. The team lowered power consumption using actuator stiffness control, lightweight mechanical parts, and a simulation-trained locomotion policy. The result expands the operating range of legged machines operating in rugged environments.

THE TEACHING ANGLE

Students can debate whether hardware adjustments or simulation-trained control policies offer greater returns when reducing a robot's cost of transport.
