legacy designHere's the design for version 2 of the R2D2 Centre Leg Lift Mechanism for the 3d printed R2D2 Droid. All printed on a Makerbot 2x, 3 or 4 layers, .3 height, no support on most pieces (some do need it) and around 20% infill. Used 6mm and 8mm standard bearings and small screws / 3mm bolts to assemble. Driven by a 3000 rpm, 12v DC motor (£12 ebay) using an L298N driver board (£2 ebay) and Arduino. Planning to use variable resistor to feedback position or switch. This is a 1st proof of concept so may tweak the design but seems solid and can hold the weight needed on my R2. The base is designed for the printed R2 (interlocks to the old centre leg frame base as I've glued mine in) but easy enough to redesign another base. As always the STL and original 123D design files are shared as I'm not great at putting together assembly manuals and like to share everything for people to learn and tweak as needed. Any questions please comment and I'll try to help as much as I can.. Still a work in progress. Here's a video of the first installation in action. https://youtu.be/MBka6m2LaSM and a link to the 123d design files are https://1drv.ms/f/s!AjIlFUf9uEzo9ylmublj7R01plZ6 added the Potentiometer bracket and arm to measure position along with a modified top bracket for cable management and a plate to mount the L298N driver board.
