Robot control by wireless

nuttaphong191 said:

I am building a robot that will be controlled by a remote PC, via a wireless link of some sort. The PC will receive sensor data from the robot wirelessley, process the data by writing some software, and then send out instructions to set the a microcontroller's I/O lines high or low, again wirelessley.

Does anybody know how this can be achieved, or if there is any existing hardware out there to perform this function?
