The Rubber Wrap Seems to grab the tubes extremely well. We originally tested wedge-top conveyor belting, but noticed that it had the tendency to lock up the claw if it touched the carpet.
As far as the poly cord goes, it hasn't jumped yet, and I don't believe it will under normal operation. The rollers have a 1/8" Deep Groove machined into them to hold the poly cord so it takes a substantial amount of effort to get the belts to jump. I did notice some issues with the belts we used for reversing the top and bottom rollers though. It seems that when the tubes contact the cross in the belt it can bind up the mechanism. It should be relatively easy to fix that though, we'll probably add a piece of aluminum round bar or something similar as a Mechanical stop and also add a limit switch to prevent the operator from over driving the claw, as well as giving much needed feedback during both autonomous and teleoperated modes.
