01 / STUDY

Mechanism and experiments

JPL studied controllable adhesion to smooth surfaces with gecko-inspired grippers. LEMUR prototypes moved across mock solar and radiator panels, while related grippers underwent parabolic-flight microgravity tests.

02 / CONTEXT

Test conditions and scope

External station inspection and repair are application objectives. Published demonstrations concern ground and simulated-microgravity conditions. The station image is a concept illustration. These smooth-surface gecko grippers differ from the microspine grippers used on rock-climbing versions.
