Controlling motors through pc

Hi,

as a new project I'm attempting to control a laptop wirelessly and allow it to move. You may have seen he sheldonbot on the big bang theory, my inspiration. I'm having a little trouble with controlling motors from a separate computer over wifi. Perhaps some motors, transistors, and python coding could help?

Thanks in advance (:

Below is a simple method that you could tinker with.
