I am attempting to link 2 different motors (size, hp, make etc) together, so they steer together.
I would typically just tie them together with an auxiliary motor tie bar but in this case that is not easily possible.
The main engine is controlled by pypilot, and is physically moved using an electric hydraulic pump.
So I got to thinking about using a potentiometer on the main motor as a motion/position sensor, linked to a linear actuator (with optical feedback) on the auxilary motor. I want to link them together using an Arduino or esp32...
As I dig into this I am realizing maybe I am over simplifying the project.
I am pretty sure I will need to know the position of each motor, so feed back is required. But how do I keep them sync'd? It would be impossible for them to move perfectly together as one is much larger than the other, so I am afraid they will get out of sync?
Any ideas how I could achieve this.
Basically I think need to send instructions to move to a position rather than moving for x seconds in a direction.
Ideas?
Kind Regards
