I am installing remote control on a child’s go kart for a kid with cerebral palsy palsy so his parents can control it as he has no ability to drive it himself. I have the wheel drive sorted but need help with the steering. I’m using a dc 24 volt Dc motor driven grate steering motor. Its rotation direction is controlled by the 2.4ghx remote controller but its rotation exceeds that required lock to lock. Can I use a simple pair of micro switches to limit the movement in each direction. Using the controller to reverse the rotation when the limit is reached in either direction. A simple circuit diagram will be helpful. The current is only a couple of amps. .

 

We don't know what the mechanical set-up is, but probably the simplest solution would be to use a couple of gears to reduce the amount of rotation.

 

Given that we have no information about the driver circuit or the motor arrangement it is quite a challenge to come up with a scheme to limit the rotation that will not interfere with the steering. My suggestion, based on a reasonable guess, is to provide hard stops to prevent excess steering motion, and add a series resistor to limit the motor stall current. This is based on a guess that the remote control package does not automaticly return to straight when the turn command is released.
