Robotic arm "Cpt. Hook"

An attempt to make a high precision 3D robotic arm driven by NEMA 17 stepper motors. For the moment it will be just stored here. Please do not expect detailed description or instructions until I will have a working prototype. Feel free to download it, but be aware I cannot give you reliable support for steps I did not finished yet. Also be warned, that the parts may change eventually as the development will progress.

The name is inspired by the lost arm of famous pirate. It is supposed to be attached to a desk and the manipulation area is going to be roughly 200mm deep, 200mm heigh and 270° sidewise. Motors with 400 steps per turn are going to be used along with 32 microstepping drivers. To eliminate backslash while gaining some more precision, T2.5 timing belts with 1:5 reduction ratio are going to drive the arms. Turning will have reduction rate 1:10. If motors will be able to stay on microsteps the precision of the movement would be close to 10μm in the designated area.
