Acrobots | 2026 Release |

Underactuated systems are often more energy-efficient because they utilize natural physics (like gravity and inertia) rather than fighting against them with heavy motors.

This joint is powered (active). By moving this single joint, the robot must generate enough momentum to swing its entire body upward. Acrobots

This joint is unpowered (passive). It hangs freely from a fixed pivot point, much like a gymnast's hands on a bar. engineers can improve:

The lessons learned from Acrobots go far beyond the lab. By studying how these machines manage underactuated systems, engineers can improve: Acrobots
