Based ABB 460 Palletizing robot, this machine uses parallelograms to keep the finger tip level with the floor at all times. Three NEMA17 stepper moto move the arm. Limit switches help it find home position. In this fit veion I'm using 2x Adafruit Motor Shield v2 and an Arduino UNO for the brain, which I've taught to undetand GCODE and Invee Kinematics.
If you can't make the parts youelf, 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 controvey.
