Looking into grabber mechanism designs now. I'm thinking that the top jaw should be a linear actuator and the bottom powered by a sprocket. A 50mm stroke actuator at 5:1 lever ratio would give me 250mm range of motion on the tip of the arm along with plenty of speed. Looks like you can get a 50mm Gimson GLA-750-S with around 200Kgf max, so that would result in 40KG of holding force at the tip of the arm, which seems plenty to grapple a 13.6kg robot.

Did you make that animation in Maya?
