Hello. I'm creating a simple RC car and I have faced a problem:
the main and steering motors are fed from the same battery. when I turn left, for example, huge current is drawn to steering motor, as it doesn't rotate, and so if I want to steer while going, it slows a lot, in most cases it even stops. what shall I do?
My guess would be that the steering mechanism is binding real badly when turning left, that is if turning right is pulling a decent currant and/or the battery is just barely sufficient
You may be able to find a resistor that can be placed in series with the motor of such value that the motor supplies enough torque to turn but the stall current is not too high.
Yeah, do what alec_t suggested. I had the same problem with my old RC. I used gears to increase the torque output from the steering motor, and it worked great
I can't change motor, I bought a RC car, took whole PCB out but left motors in, so it HAS to work with those motors under some configuration. any help?
On my autonomous/RC car, when it turned full right/left, the linkage would stop, but the motor was still "ON" and sucking alot of current, causing the micro-controllers to reset. I thought it was a 'bug' after countless hours(days),
I realized what was going on I added two steering limit micro switches. They cut the power to the motor when at full lock, but allows the opposite steering to reverse the motor. Hope this may help you.
