Based ABB 460 Palletizing robot, this machine uses parallelograms to keep the finger tip level with the floor at all times. Three NEMA17 stepper motors move the arm. Limit switches help it find home position. In this first version I'm using 2x Adafruit Motor Shield v2 and an Arduino UNO for the brain, which I've taught to understand GCODE and Inverse Kinematics.
If you can't make the parts yourself, I can make you a set of parts.
I will be releasing bigger and better robot arms throughout the year and I'll do my best to keep them open source and open hardware. I want to do for robot arms what MakerBot has done for 3D printing, minus the controversy.
Updates
2013-01-02: improved the design for ease of assembly and maintenance. Also mounted the circuit board to clean up the wire routing.
2015-12-15: Removed links to buy sets of parts. Not offering this particular kit any more.
2016-06-23: Added missing tendon.dxf
2016-12-14: updated with new link to assembly and programming instructions.
