Miniature robot for wall-to-wall transitions

Kirigami-inspired adhesive tracks and negative-pressure preload enable a miniature robot to transition between surfaces of varying curvature.

01 / STUDY

Mechanism and experiments

The system combines adhesive tracks, fan-generated preload and a rear stabilising mechanism. The paper reports transitions on variable-curvature surfaces and actual engine stator components.

02 / CONTEXT

Test conditions and scope

Experiments covered variable-curvature surfaces and actual engine stator components. Passage between specific surfaces depends on transition geometry, surface condition and contamination.
