If you compose a robot from multiple model()s then my intention was
that their independent gripper_return and obstacle_return settings
should be respected. If you find that it's not working that way, it's

I'm working on this very hard. I hope to have a usable version with
the basic sensors in CVS in the next couple of weeks. At that point
I'd be extremely happy to get some help porting the rest of the
models to 3.0 while I refine the GUI, external API and documentation
for a release before Christmas.
meanwhile, just for fun, here's a screenshot of 3.0 in development.
