You can't do that in C, C only acceses everything on your hard drive, but it can't be used to program things outside it.
Maybe you meant pictures running on your screen that look like robots...

Lots of robots (yeah robots) are programmed in C++. You connect them to the computer and you program them. In fact, C++ cannot access your harddrive, what it does is call the OS, and it is what access the HD.
