Untethered One-Legged Hopping

Impressive demonstration of balance.

"Passively compliant" - adjusts its movement in response to sensors.

"In industrial robotics, the term compliance refers to flexibility and suppleness. To define what compliance is, the definition of non-compliance is useful. A non-compliant (stiff) robot end effector is a device which is designed to have predetermined positions or trajectories. No matter what kind of external force is exerted the robotic end effector will follow the exact same path each and every time. On the other hand, a compliant end effector can reach several positions and exert different forces on a given object...Active compliance must be set by the user and will vary for each application process. It is commonly set up via software programming of the servo joints and uses sensors...Passive compliance is applied during the setup of the robotic cell and will always stay active in the background"

Boston Dynamics also showcased the ability to jump, with arms anticipating and compensating for balance.


This jumping robot winds up from a low crouch for maximum height.



Nice demonstration of how this jumping robot can traverse terrain very difficult for other robots by jumping over it.
