They cheated! But still a nice conversation piece to have on the table! I wonder how load the servos are?

interesting. so basically, its a cnc magnet that the "robot" follows?
clever way of doing it. im sure there are plenty of applications for this.

Having reread the explanation this morning I am still unsure how the mechanism to open and close the gripper can work. Is the author a member here?

Having said that A very interesting bit of lateral thinking.

I'm not the author, but I think I know how the gripper works.

The assembly is pivotted, and then the magnet is mounted on that. As the base magnet tips back and forth, the gripper assembly will tilt, so lowering and raising the gripper.

I don't think it can close - just tilt.

Ain't it cute!

Well, whether or not it can grip (and I won't lose any sleep over it) it's still a nice bit of fun.

The turn on a dime shows the gripper opening and closing. Although I suspect there is little force there.
