Why not attach them to the bottom and have the setting machine underneath?
- nsxwolf 3y agoHow about electromagnets?
- Rapzid 3y agoIt looks like dangling is key to the untangling.
- justinsaccount 3y agoWhere do the pins go between the first roll and the second roll??
- xp84 3y agoUp, I think. The YouTube video someone linked near the top shows how both work.
- justinsaccount 3y agoMy reply was to this suggestion: > Why not attach them to the bottom and have the setting machine underneath?
- sb8244 3y agoPins are pretty heavy and seem like they would be difficult to reliably stand upright from underneath. Just guess—i don't actually know

- paxys 3y agoThat doesn't make sense because you have to move the pins out of the way after they have been knocked over. If they are attached to the lane at the bottom then where do they go?
- derefr 3y agoSteelman of this concept: • Make holes in the lane right under the pins, where the pins are each sitting on a little two-sided door with a hole in it just wide enough for the string to go through to the bottom of the pin. • Knocked-over pins pull on the string, which causes their door to open, the pin to get pulled down into the now-open hole, and the door to close after them. • Once you've cleared all the pins, the doors all open up, the pins are pushed back up, and the doors close. • Throw in an optical sensor that notices any pins that are out-of-place but not tipped after a bowl, and brute-force resets them by swallowing them and then spitting them back out. (Or, alternately, swallow all the pins, then spit back out the remaining pins, after every bowl.) In a way, it's still a pin-setting machine. But it's more like ten little individual pin-setting machines, that can't interfere with one-another. The pins' strings could still get tangled, though. So it's not a perfect solution. --- That being said, my own favored solution would just involve a regular pin-setter "sweeper", plus a robot arm behind the lane that does its re-setting using Computer Vision using top-down and side-on lane cameras. In other words: have a robot do exactly the job that a human pin-setter did. Robots don't exactly have great dexterity for this kind of thing, but you can make it easier on the robot by putting electromagnets under the lane at each pin position — and a bit of a light ferrous metal on the bottom of each pin — so that the pins can just snap into place when brought close enough to the target zone, rather than needing to be set down carefully and exactly. (This would have helped human pin-setters too!)
- dexzod 3y agoOr make each pin a robot, that can standup and bring itself to the correct spot
- rini17 3y agoHeh. But making them sturdy enough won't be cheap.
