    Hi! Here I go again. LOL.
    While testing the platform, I encountered problem.
    The motor is turning 360deg when the game' pitch is downhill.
    I think the problem is the potentiometer, but to make sure, I am asking for your opinions.

    Here is the video URL. Pls do watch.


    Thanks,
    Ralph M.

    What controller are you using?
    Have you ensured motor direction is accurate?
    Could be PID settings. What are they?

    I think its your joint. If you look the POT isnt going 360 but the design of your arm on your pot connect to the motor allows for the pot to go from say 1 to 180 regardless of the motor direction. Motor is going 360 but your pot isnt.

    Cool, didnt see the controller clear. Looks like something with the arm on the POT more that I look at it.

    Other then that its trying to get back to its starting postion using the shortest path of resistance in the POT

    Have you tested the pot manually turning it by hand and can you post screenshots of your settings.

    Already figured out what the problem is; the lever connected to the pot.
    I will continue fixing this tomorrow. I'll update you.
