we are in the process of making a new drone. It’s an coaxial drone and will need 6 servos.
To not use so many wires, we decided to use a CAN-bus. But how exactly can I connect a servo to the CAN-bus? How can you translate a PWM-signal to CAN and the other way around? Is there a board that can do that? Or do I use something else?
I saw a guy (http://www.olliw.eu/2017/uavcan-for-hobbyists/) do it with ESC’s but to be honest: I didn’t understand how he managed to do it And that’s the closest to a servomotor, right?
What am I missing? Which Hardware will I need? Can I actually do it? Can I “steer” my drone via CAN?
Sorry for bad english, I’m trying my best
