Do you know about Pyro? It supports Hemisson robots:

The simplest way to control a single robot is probably to use 
module-level functions to control the robot.

You can still have a robot class; the module functions can delegate to a 
single instance of Robot. The turtle module does this, too; it has a 
global instance of Pen which is used by the global functions.
