Modified Canadarm End Effector for Space Shuttle/Payload Maneuvering with OBSS
Author(s): Palash Sharma
Abstract: Deploying orbiters/payloads in space stations with micro gravity are a major challenge faced by space agencies. Currently used methods used for safe gripping of payloads uses a mechanical robotic arm with multiple degree of freedom. This arm is called Canadarm, but it lacks maneuverability over safety. Major challenges faced are harsh surrounding and rare choice of materials sustaining high stresses. Design limitations upon these materials are another set of challenge, which restrict the degree of freedom of orbiters connected with Canadarm. Proposed model is a modified End Effector for currently adopted Canadarm with OBSS (Orbiter Boom Sensor System) installed for thermal loss inspection of the orbiters. This end effector consist of spherical type key locking system with rollers as in-contacts for a high maneuverability over currently adopted cable gripping system.
