Vesc on large self balancing robot

So I have a unique issue in that I want something to balance that is potentially very dangerous to have not be on point with the PID settings from the first time it’s running. It’s about 6’ tall and over 400lbs. It’s got a pair of large hubmotors for the drive that can handle some real power. There’s “training wheels” on in the pics but they’re removable and will hopefully only be needed when powered off in the grand scheme.

So here’s my issue… how do I figure out what PID values to use? ChatGPT told me there’s a way to run an API and it could do it for me but that’s actually significantly more complicated than it led me to believe lol. This thing should have a top speed of 60mph so I’m wondering if I turn the speed way down if I can calibrate some PID values that will stay relevant when the max rpm isn’t restricted. Or any advice? Thanks!

You aren’t going to find many good guides for the older balance package.
I would set it up like a onewheel using guides like this:


Download a premade tune, and play with the safe numbers to get an idea of what you want.

What vesc? built in IMU?

there are some tricks to IMU wizard that can be messed up.

Yes it has the built in IMU. It’s the little FOCer 3 I believe

[WIKI] IMU Calibration Wizard Guide (VESC Tool 6.02+)

I think you might need balance package due to the multi-esc segway type drive
