Sorry for posting so many scenes, but I'm absurdly proud of this. I consider it my best machine to date.

A robotic arm that is programmed by changing the collision groups of a rotating group of circles. The program-drum rotates, the mechanism reads the data off the circles, and moves the arm accordingly.

The program will keep on recurring as the program-drum does a full circle, continuously moving rectangles to the box.

GahahaHHhhhahHHHa that is awesome.

You could also try a rotary version of conundrumer's mechanical robot arm.

That's a good idea, I'm a bit pissed off I didn't think of it myself.

On the other hand, I still don't fully know how conun's arm work, so it just wouldn't be the same.

Conundrumer's arm uses tracks above the arm, which push and pull cgear-racks, which turn cgears, which are linked to the arm's joints, each track has a different collision layer, and so acts on a different joint

I got that part, it's where the differential came in where I got confused.
