We used this type of belt for our rookie 2012 Rebound Rumble robot to pick the basketballs off the floor and raise them to the cup which would lift them to the shooter. It was probably the most reliable system on the robot. I was not as involved that year, so I don't know why, but the belt was taped together rather than just held with the barbed connector. I suspect that it was because we were running it around about 1" diameter rollers (larger is recommended).
