I didn't realize that either end of the robotic arm could act as both a "shoulder" and a "wrist", and that it could plug it's "wrist" into a second power-data-grapple fixture and then unplug it's "shoulder", effectively walking from one fixture to antoher.
How may fixtures are there, and how many different walk-off maneuvers can the Canadarm-2 do? For example, if there were three fixtures A, B, and C, the answer could be as many as six (A->B, B->A, A->C, C->A, C->B, B->C) but it could be less if A and C are too far from each other to go directly.
Are there other animations of the arms's various walk-off maneuvers that I could look at besides the one in this cool video? (Walk-off after 01:00, but it's a cool video so watch the whole thing!)
Uploaded on Aug 24, 2010 This NASA video features astronaut Dottie Metcalf-Lindenburger giving an overview of the International Space Station's Robotic Arm. I received the raw video of Dottie on camera (recorded on ISS during STS-131) and was asked by the NASA client to polish it up. I produced and edited the resulting product.
