01 / STUDY

Mechanism and experiments

The research models friction and joint constraints, and validates shape estimation and navigation. The figure shows navigation through an aero-engine blade mock-up. “Contact-aided” describes contact within the compliant mechanism.

02 / CONTEXT

Test conditions and scope

Blade-model experiments validated navigation and shape estimation. Loads, precision and reliability with maintenance tools need further testing.
