KISSarm: Modular Robotic Arm
This is the Keep-It-Simple-Stupid Robotic Arm.
It was designed to have as little wobble as possible and uses no special hardware. All driving motors are usual NEMA17 steppers, the controlling part is based on a RAMPS board running on unmodified Sprinter firmware ( https://github.com/kliment/Sprinter ), but this is temporary.
Also, most connections are inspired by the NEMA17 design and can be combined in any configuration that is neccessary.
The design was inspired by KUKA industrial arms and by a KSP mod called B9 Aerospace (HX module family specifically).
