Re: Set Motor position with Encoder?
You can't do this without the use of some other kind of sensor, as the encoder value resets to zero when the code is rebooted.
What you could do, and many teams did in the past with Recycle Rush elevators, is use a limit switch that resets the encoder count to zero (wherever the arm is when it hits the switch would theoretically be zero degrees), and use closed loop control to move and hold the arm at a certain number of encoder ticks.
Or if you're always going to be booting the robot up with the arm at zero degrees, you wouldn't even need a limit switch, just a way to reposition it to the same place every time you want to boot or reboot the robot.
