would it be possible to get a close up of the rollers or can you tell me how you made them, we are having problems keeping our belts in the correct positions.

thanks

We haven't had any problems with ball handling. We squeeze the ball down to 7" diameter. The rollers are made of 2" ID pvc pipe (painted) with small grooves to hold the belts in. The pneumatic tubing spikes help hold the belts in place. We also have 7% length stretch on the belting. On the rear conveyor system we are also using pieces of the timing belt that came in the kit rivoted to the tube to help prevent the belts from sliding around. Hope this helps!

Nice looking robot!

How do the balls funnel down from a 2 ball wide conveyor to a single shooter without jamming?

7% we only did 3% and they were bending our PVC like mad... We ended up switching to something different...
