Re: Building fully flexible tail (several joints) with minimal actuation required

There was some talk about springs in the structure of the tail.

How about this...

try a piece of thin metal, with eye-hooks bolted on along the length Tie off a string/rope/cable to the tip eye-hook, and run the string through the other eyes (acting like the pulleys Al was talking about.) You'll need / want to play with it a little to get the right look. Cheap, easy, fast, robust, not real precise, not easy to control.... but I think it might get the job done. The metal strip is the body AND the spring.

(My prototype for a compliant big ball grabber for 2004 - never to be used)
