Note that The Gluss Project is part of Public Invention, and therefore everything it does is completely open-source. This means that the STL files for the Turret Joint are reusable: http://pubinv.github.io/turret-joint/.
The electrical architecture is based around 6-actuators modules consisting of a 12V NiMH battery pack and an Arduino Mega with a custom shield. The unpopulated PCB can be ordered from Oshpark: https://oshpark.com/shared_projects/fijpozoB.
The Eagle CadSoft files for the board are: https://github.com/PubInv/gluss/tree/master/GlussPCBv0.1
