: Would any team that has used ball rollers (counter-rotateing shafts that pull balls into a bucket, basket, ect.) in the past share how they got the rollers to spin in oppsite directions without using 2 motors?? we dont want to use gears if we can get away with it. Also what motors did you use? Any other advice is welcome.

A simple approach is to use two spur gears. If the gear attached to the motor spins direction A (say CW), then the second spur gear attached to the output shaft will spin the opposite direction, B (or CCW). Hope this helps.
