rc for motors
« on: November 04, 2008, 01:50:44 AM »
Hey I have built a robot and now want to build an rc car.
I have a radio control and some parts but i don't know how to put together the electronics using a motor instead of servos. I'm using 1 motor for the wheels and a servo at the front for turning please help someone!

Youll want some way to make the single motor drive the wheels. Easiest to implement is just stick a gear on the axle of the back wheels and stick another on the spindle of the motor and stick em together. Youll want to experiment with gear ratios as well to determine if you want/need more torque or more speed. Depends on the motor your using. I would generally lean towards more torque but it depends on what id be using for for :)

Theres a number of different ways to steer front wheels. Im tired as hell and such so I wont give examples at the moment. But I assure theres some easy ones that im sure you can pick up on your own :)

I must disagree.  If you want to use a single drive motor with Ackerman steering, you need a differential for the drive axle.  A solid axle will not allow the car to steer.  Google "Ackerman steering" to see why.

I see what you are saying but its still the easiest to implement. I didnt say it was the best in any way :-p It would still work for the most part
