I’ve got this amazing actuator designed by LoboCNC that does a 38:1 reduction from a 35mm stepper which will be quite effective in a robot arm, but I’m wondering if I can also extend it to be a slip-ring at the same time to carry the 20v across the whole robot? The rest of the signals for coordination should go across Bluetooth, so this will be a robot with 0 wires possibly.
Here’s the 2mm wide copper tape I’m trying to use and the PLA brushes hanging off the top side of the actuator that will touch the other side of the ring. I think this just might work, but worried about the copper wearing out if I’m just using tape. However, this is just a hobby robot, so probably would wear out long after its usefulness.
