I am a big fan of Coyote as well as Donald Hudson's bots from Battlebots, I was wondering what goes into building a clamper like Coyote or Lockjaw? I am aware of needing linear actuators but, what else would I need, I assume I need a motor/motors and batteries to operate the jaws.

Am I right into also thinking that I would need a separate power link for the jaws?
