Mechanism and experiments

The work uses tunable energy barriers in a bistable mechanism to produce different jumping behaviors. The figure shows the mechanism, motion sequences and a fingertip-scale prototype.

02 / CONTEXT

Test conditions and scope

Experiments focus on bistable mechanisms and jumping; work in rubble or engine interiors was not validated.
