I wonder if using two "arms" under the board would result in better movement - you'd need two motors to control the angle of each arm, and some way of extending the arms, but then you'd be able to use one arm to move any required pieces out of the way, while the other arm moves the intended piece around. You'd use a polar coordinate system, instead of a cartesian one, to keep track of where the arms are and where they need to move.
Plus, you'd be able to move the pieces off the board when they're captured.
- sitkack 2y agoI think you are describing a 5 bar linkage or parallel scara robot. https://www.youtube.com/watch?v=NNtsMVEx-CM https://www.youtube.com/watch?v=NNtsMVEx-CM
- pavel_lishin 2y agoNot quite. I'm imagining two independent arms, probably placed at opposite corners. They'd have one servo for rotation along a 90 degree angle, and another mechanism for extending or retracting it. I can't really draw something at the moment to illustrate what I mean. (But practically, yeah, what you linked is probably what would be required, otherwise I don't know if it could support it own weight.)
