It is well documented and constantly updated. It comes in "blue" and "orange" version, the blue uses stepper motors, the orange DC-motors. Encoders provide 12 bit resolution with an arm length of some 500mm. That results in less than 1mm accuracy (more realistic is 2mm).
The arm is developed by Andreas Hölldorfer, a master student at the Karlsruhe Institute of Technology (KIT). Great work Andreas! You rule!
