Robot Arm

thingiverse

A robot arm driven by servos and controlled via an Arduino board is being developed. View a video of it functioning as a business card dispenser here: http://youtu.be/wh9E098Zt5k. Watch the basic joint move in this clip: http://youtu.be/bu_qJ_hEIAg, and the basement turn in this one: http://youtu.be/1W78memrASw. However, please be aware that this is a work in progress. To build your own robot arm, print each part except for "joint" twice. You will need three servos (e.g., Corona DS558HV), six 67002RS ball bearings (10 x 15 x 4 mm), 12 M3 x 15 mm screws, and four pieces of 8mm aluminum pipe for wire placement. Additionally, you will need a power supply, wires, and an Arduino board. An update from January 24th, 2014, includes two versions of the "joint" part: one with minimal gap and another with more space for cable management. There are also two versions of the "turn table" and "base counter" parts, with the compact version and a roomier alternative. Be cautious when mixing parts from different versions.
