Been thinking of when I do my low-rider, putting two 5’ square sheets on a Paulk workbench, so the whole thing can be multi-use and stowable.
Pretty much table tennis sized in the end, so I’ve been looking to low-ball purchase a ping pong robot, and I snagged one for £50 on eBay. It’s a top end one costing over a grand new. The one I got is missing the control panel, so it’s a project:
I gave it a look over, and there are 5 motors, which all wire back to the main box, and the missing controller would plug into the main box and control motor voltages. So the good news is, I just need a micro-controller approach, and I can really improve on the analog, knobs based control box it came with:
I also found someone else had modified one of these:
He talks about RC servos and PIC controllers. I was thinking of using an Arduino or RPI type board to control the motor voltages, but I will have to reasearch this.
