Cheap robot base?

Hi guys… im putting together a robot myself, which ihad planned to control from an x86 mb (the epia nano)… however, i’ve recently thought perhaps the wrt54g router maybe the perfect solution…

Its very hackable, cheap as can be, runs linux, reasonably low power, has a serial port (among other things) and supports wireless networking…

Has anyone attempted something like that before?

Regards, Paul
