Publication integrity record
Aerial continuum manipulator with kinematics for variable loading and minimal tendon-slacking
This page is the evidence record. It changes as evidence arrives: a trusted timestamp, an independent retrieval, a custody deposit. The disclosure itself (/p/OT-2026-000002331) never changes.
