I’m looking everywhere to get a PCB designed+coded, and thought of y’all coz I use platformio in the Makelangelo polargraph robot firmware. I figure a lot of the right talent hangs out here, yes?
I’ve made many robots over the last decade. I’m currently trying to make a harmonic gearbox + stepper motor combo (think big big servo) that can be daisy-chained. The goal being to make one servo and repeat it 6 times to build an arm.
Most DIY motor controllers use an on-axis sensor like the AS5147. Great device, inconvenient placement. I need a pass-through for wiring so all the cables can be sealed in the shell of the arm.
That means a sensor that has a through-hole. I found the IPS2200 on digikey.
That means comms that daisy-chain, too. CANbus seems a natural fit and many STSTM support it. In a perfect world the first unit in the chain is software-flagged as master.
Here’s more about the requirements.
Open to other ideas, approaches, discussion. This is, of course, a paid gig.
I’m aware it could take a couple of months to get it right.
