What do I need to control a R/C car with my computer?

 I'm building a project that needs to control a small car with my PC in order to make it move forward or backward, left or right. I've been looking how to do it but I've not found a way with the USB port. I've also read that I can modify the remote control of my car in order to do it but again I need to do it with a USB port. Thank you for the help.

The USB handles data, and 5V. If you need to go via USB you'll need to buy something and install software. Some kind of microcontroller for example
