I’m excited to announce new python bindings for communicating with moteus controllers! A simple example from the README:

import asyncio
import math
import moteus

async def main():
  c = moteus.Controller()
  print(await c.set_position(position=math.nan, query=True))
  await asyncio.sleep(1.0)

asyncio.run(main())

This code will try to locate an fdcanusb on your host and use it to communicate with controller with ID 1. All of those details can be customized through code depending upon how you construct things. The library is pure python, although it doesn’t work on Windows currently because it relies on an asyncio aware pyserial wrapper that doesn’t work there.

At the same time, there is a parallel python library “moteus-pi3hat” which only has an armv7l package. This provides an identical API for working with the pi3hat on a Raspberry Pi. It lets you configure which controllers are attached to which bus (by default it assumes everything is on bus #1). After setting that up you can use an identical API to command and monitor the controllers.

Thanks to everyone in discord who helped test!
