Mechanics

I carved all parts with my CNC v3.2 from 5mm polycarbonate plates. Use 5mm plywood if you don't have access to a CNC router, because polycarbonate is tricky to process manually.

After the first test runs I have replaced the 30 teeth sensor disc by a 12 teeth version with 7mm tooth width. The distance from the center lines of the optical sensors is 10 to 11mm. A 8 teeth gear is glued to the output shaft of the motors. Instead of the gears carved with my CNC machine, you can buy module 1 gears.

The frame is made of 20x20x1000mm steel square tubes, because I had them in stock. Use aluminium square tubes to get a lightweight frame.

WinchBot is hanging on three cords on the ceiling of my photo studio.
