Well, that's pretty funny :-)

Well, pretty much the only (free) Smalltalks you can actually use 
right now on anything resembling an embedded system are:

Squeak on PDA (Linux or WinCE)
PocketSmalltalk on Palm PDA

You could use a PDA running Smalltalk to do all the high-level "brainy" 
stuff for your robot, and talk to your little 8051 MCU over the serial 
port to actually do stuff, like control motors and sensors of the 
robot. That is the approach I took with MicroSeeker, my autonomous 
submarine. A PDA or an embedded single-board-computer runs the control 
software in Smalltalk, and all the hardware interfacing is done with 
PIC micro-controllers.

Later,
