Re: PVC Rollers?

In 2011 we cut PVC couplers to act as guides for our Polly cord with no groves at all. We wanted its to act as a slip clutch for our rollers on our claw that year. All in all it did the job. It had enough friction to pick up the tubes but not enough to stall out the motors once the tube was all the way in.



Last year we cut grooves directly into schedule 80 PVC and it worked pretty well as long as the cord was tight. Once the cord stretched a little it started to walk out of the groves but to fix it all you had to do was cut it and tighten it(probably like once a competition). The grooves where just shy of half of covering half of the cord which isn't ideal but worked all season long on both team 1592s and team 801 twin robots.



Looking back on this season I would Probably go with some ABS just so I could get a deeper grove but if is all you have access to its pretty cheap and its everywhere so go for it especially on a prototype. The Nice thing about first robotics is that there is more than one "right way" to solve a problem.
