  • Motors slowing down?

    I have finished an autonomous program and I have tested it a few times. It has worked great so far but after a few runs, two of the motors have begun to slow down. Almost like they have stiffened up. I am unsure if this involves the program, considering how it worked fine a few times before...They type of motors are the Andymark DcMotor Neverest.

    Maybe slipping set screws or low battery voltage?

      I'll have to check the screws...the battery was switched out when it first started, same result with the fresh battery. I tried to inspect it to see of anything was caught and when I moved the wheel by hand it clicked. I'm not sure if that's normal or not, so I am concerned that it may have burned out from repetitive testing.

        Elevate the robot on some wood blocks so it doesn't run away. Examine each wheel while driving it to check if anything unusual (i.e. something slipping, wobble etc). Try applying friction to each wheel and see how it reacts. If you can easily stop a wheel, something may be wrong. Also hand spin each wheel while they are not active to feel the friction of each wheel. They should feel the same. If one is harder to spin than the other, examine it closely to see why.
