POLAR DRAWBOT

This is my redesign of mechanical parts used to build a Wallmount Polar Drawbot . The electronics and firmware comes from Dan Royer's "Makelangelo project" (Makelangelo SOFTWARE - Makelangelo FIRMWARE ) using V1 version of Adafruit motor shield but I used an DK Electronics motor shield I made several test trials using parts found ready around many projects, but none seem to match the requirements I would like to obtain. So I completely redesign all parts. Following several tests I developed 3 kind of pulley: one is to be used for smooth cords and others for synchronous trasmission made with ball chains. 3 types of ball chain can be used: Ø 3,2 mm all metal chain with pitch of 4 mm , Ø4,4 mm plastic ball and cord with pitch 6 mm, Ø4,4 mm plastic ball and cord with pitch 12 mm As a counterweight I used some exhausted "D" type batteries and for that I made several kind of holder to hang them. video assembly instructions: https://youtu.be/bMyd1Vm-Nrk https://youtu.be/hQ8BQ0GsLiE https://youtu.be/30_FnJPDODY http://www.eezyrobots.it
