Printable Robot Arm

thingiverse

This is my initial attempt to build a printable robot arm.\nI drew inspiration from the Zortrax demo, but I created it with my own unique design.\nIt hasn't been tested yet; I'm still printing and testing parts.\nThe assembly should fit together smoothly, although some tweaks may be needed.\nA total of 8,608zz ball bearings are required to assemble the arms.\nTwo M8x60mm screws, two M8x65mm screws, and four nuts (the best-case scenario with self-locking) are necessary for mounting the parts.\nThe main motors used in this project are Nema17, while a Nema11 motor with a planetary gear is planned for use on the forearm.\nM4 screws will be used to mount the various components together.\nRemember that this is still an untested project - I've only completed the first joint and some other parts of the arm so far.\nThe videos showcasing my robot's early stages can be seen at http://youtu.be/O5_gnh2r2Gw, with an additional video from December 16 showing all the printed parts at http://youtu.be/XGjULACXRRQ. On January 19, I uploaded a more detailed version of the arm to Thingiverse - https://www.thingiverse.com/thing:601036.
