Parallel robot moving nuts

Hello,

Firstly, my apologies for my english. I'm french.

The purpose of this machine is to make automatically stop-motion. I give it a video and it draw each picture of video with nuts.

This project isn't finish. Actualy, it can take nut and place it wherever I want on a surface. But, nut doesn't stay in the good position, it rolls or falls. Probably because geometry of robot is not perfect and that nuts are placed with precision of 2mm above surface.

To avoid having the nuts through on the electromagnet,I shake it and I varies its power. So nuts shall be in a good position on electromagnet. This works 95% of time !

Presently, I try to improve quality of placement of nuts on the surface.

To be continued.

Have a good day.
