01 / STUDY

Mechanism and experiments

The tethered 4.5 cm, 1.48 g robot uses electroadhesive pads and passive origami ankles to crawl on vertical, inverted and curved conductive surfaces.

02 / CONTEXT

Test conditions and scope

Tests validate tethered locomotion. Autonomous camera inspection remains an application goal; this is not a 10 mm wireless SWARM unit.
