how do they work?

is there a driver ic available?

i need to use it for steering control of a rover.

thanks
 
There are single board controllers available, but no IC as such.

Do a search on google under "rc servos" and "rc servo contoller". You'll find out everything you want to know.
 
it seems that servo's are controlled by pwm..

does any one have a circuit wherein you have 3 switches; 1 switch produces a 1ms pulse, the 2nd switch produces a 1.5ms pulse and the 3rd switch produces a 2ms pulse?

thanks
