For us, we are using dual mini-toughboxes with 1-CIM and mini-CIM, one on each side, then double chain reduction of 15 from the CIM output to a 26 tooth sprocket, then a 36 tooth sprocket to a 96 tooth sprocket. Total reduction should be nearly 27:1. We are using 1/2 EMT loop connected to two arms. The 96 tooth sprockets were made by our sponsor (Andy Mark six hole pattern - 1.875 inch bolt circle).

We're throwing the ball from white line past the other white line, over the truss, during the Southfield MI event. We missed some shots because we didn't have the shooter dialed in perfectly (made 2, missed maybe 5, 10 pointers) and hit the upper target area bouncing over the top.

We also calibrated for shooting into the 1 point goal over robots. We were 1 for 2 with little practice.

Thanks CD for previous posts that led us in the direction to have more velocity and less torque (F = 1/2 * mass * velocity squared)

Our design is based on the Boom Done design completed in the Robot for 3 Days competition. This year's motto: If Joe's team can do it in 3 days, we can do it in 6 weeks!" (4-6 high school students, 1-1/4 engineers, 1 dad for 6-8 hours).

Best regards,
