    Sliding horizontally or vertically along pipe? How about some worm drive tightening bands (think like hose clamps) at either end. These would tighten & loosen around the pipe. A long straight drive gear would pull the back half forward. The rear band would tighten, then the front band would loosen as the gear pushed it forward. A simple caterpillar form of locomotion.

    Tell me more details about the requirments for the collection of the ball. Is the ball/basket at a fixed location or does it need to be adjustable? If adjustable, in which axis and degree of motion?
