Danny Van Den Heuvel and Sepio’s implementations of the Thor robot arm use an Arduino Nano to interface to the sensors in the upper joints and the effector. I’m trying to do something similar but I’m finding the area around the Nano to be pretty crowded. Does anyone have any suggestions for creating an interface board between the Nano and joints 2 through 6? As for a wire count I have 16 wires coming down from joints 5 and 6 through the upper slip ring, 14 wires coming from joints 3 and 4, 3 wires coming up from joint 2 and 5 wires coming through the lower slip ring interface board. 12 of the wires coming from the ; joints 4, 5 and 6 steppers don’t actually connect to the Nano but pass on through to the lower slip ring.
I’m definitely interested in seeing how other people have handled this.
