It's always surprising to see the accuracy of a real industral motion system hitting the exact same point on the cardboard. I built a sewing machine before and was surprised to put the material back through for a second pass during debug and see it apparently not sew at all.... On investigation, it was passing the needle through the same holes it made on the first pass!

I saw a video on something similar with those ultra precise bench guns. Guy dialing in a bunch of settings and hit the sweet spot for repeatability but didn't realise, and spent several minutes trying to figure out what happened to his bullets, figuring he'd screwed something up. He'd actually put 4 bullets through the same hole from some unreasonable distance, without even tearing the edges.

My first thought would be to make the marble cup deep enough to hold the marble at the very bottom position. You could then use the longer arm and accelerate for 180 degrees to the top position. Instead of the immediate stop it could slow just enough to release the marble then use the remaining forward rotation to slow down to the bottom starting position. That deceleration would be much more gentle. The feeder would need a little redesign with a spring catch to allow the arm to pass by then back into it.

@FarmCraft101Ай бұрын
How about you make the spoon hold the marble so that the only way it will release is if the motor stops. That would allow you to spin a full revolution to get up to max rpm before throwing. Then maybe you could cut a circle in a piece of plywood... lol.

You should curve the throwing arm and have it load closer to the motor shaft and then roll up the arm through the rotation. This way you could make the arm longer and you would have more torque to get the marble in motion, and also more speed as it reaches the end of the arm. Kind of like cracking a whip.

With a bigger spoon, would it be possible to accelerate the marble for a whole turn, or even longer? That way it should be possible to accelerate an arm of almost any length up to speed fully. It would need a different loading mechanism if you do this manually and a very stable control curve, or good covers. But that could make it properly dangerous and bring the marble up to much greater speeds.
