Our prototype last night scored 4/5, roughly. For all but 1 of our misses, the ball shot too high and went over the backboard. We figure that's most likely because we did not have a constant angle on the shot - we tilted the assembly by hand to get a rough 45 degree shot. The other one the ball was inserted at an odd angle, and exited at an angle, missing the basket to the side. Consistent loading is going to be important!
We had 2 wheels on bottom and two on top, similar to the video talked about here (except we used cordless drills to power it, not CIM motors):
