What is the best microcontroller for PC-controlled robotics?

[dingpud]

I've searched through some of the already posted threads, searching for anything on microcontrollers. My search has come up with, well...not much. So far I've been able to get some info out of some beginer robotics books.

I am interested in turning one of my old RC cars into a PC controlled robot. Has anyone out there done anything similar? I'm interested in being able to control servos, stepper motors, etc., and I understand that I am going to have to interface between the two with either a hardwire (hoping ethernet, but probably parallel port) or through an RF signal.

I'm mainly looking for somewhere to start. Any suiggestions for someon with a minimum amount of programming experience?

Thanks

think about using a plc to run your RC car

I would look into using a BASIC stamp chip with some added boards from www.parallax.com or a similar site.

Their BASIC chips are programmable, easy to understand, and you can get a specific Servo Controller Board which can take commands from the chip, including speed and distance. If you look in the accessories portal, they have tons of stuff in there compatible with the chip as well, from sensors to communication equipment. Check it out!
