HAMR-E: electroadhesive crawling on engine walls

A centimetre-scale tethered robot uses electroadhesive feet to crawl on vertical, inverted and curved conductive surfaces.

01 / STUDY

Mechanism and experiments

HAMR-E anchors to conductive surfaces with electroadhesive feet. Passive origami ankle joints accommodate local curvature. The 4.5 cm, 1.48 g prototype uses tethered power and control; experiments examined vertical and inverted climbing and locomotion on curved engine components.

02 / CONTEXT

Test conditions and scope

The experiments demonstrated tethered locomotion. Autonomous inspection with an onboard camera remains an application goal. This prototype is distinct from the 10 mm wireless units envisioned in the SWARM concept.
