Mechanism and experiments

A bistable mechanism stores energy and releases it rapidly to produce a jump. Adjusting its energy barrier yields different jumping behaviours in an insect-scale prototype. The original figures document the mechanism configuration, motion sequences and physical scale.

02 / CONTEXT

Test conditions and scope

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