No we only cross the bump. We want to keep the arm low and close to the robot to help keep a low CG.

Telescoping should be easy how we do it. Connecting the bottom of the upper(inner) tube to the top of the bottom(outer) tube with surgical tubing. We'll use a worm transmission to hold the upper tube down inside the bottom tube against the tension, unwind the worm to release tension, allowing the arm to spring up, then after hooking, re-wind the worm to lift our robot up.
