A humanoid swings from bar to bar

What changedSwingBot trains a humanoid for continuous overhead travel using biomimetic keyframes and a recurrent estimate of state that the robot cannot sense directly. On hardware, it kept moving when researchers changed bar spacing, added payloads and applied disturbances. The striking motion matters, but the more useful result is a control recipe for a dynamic task with long periods of flight.

The useful part

Why it matters

Brachiation tests timing, momentum and whole-body coordination in a way that ordinary walking demonstrations do not.

Worth doing

What to do next

Inspect the disturbance trials and reset conditions before comparing the demonstration with autonomous traversal in an unprepared environment.

Keep in mind

Good to know

The work uses a prepared bar course and remains a research demonstration, not a general climbing capability.
