I haven't modelled them in a 3D environment (although that's mostly because until I got my Amiga the hardware couldn't hack it) I have done some limited work in the 2D environment. I discovered it was much cheaper (and easier) it was to simulate a robot and then program the simulation. Unfortunately I don't have very good simulation rules yet. My first system consisted of a simulated point-source robot who navigated on an ASCII screen. If you are at all familiar with the programming "games" of CRobots or Omega, you have a good idea of what it looked like. This helps you see how wall follower algorithims work but doesn't do much beyond that. At the current stage I'm more interested in getting my homebrew robot's sensors and environment (carpet covered hardwood) modeled. If you find any pointers to references on developing this sort of model I would be interested as well. -- --Chuck McManis Sun Microsystems uucp: {anywhere}!sun!cmcmanis BIX: Internet: cmcmanis@Eng.Sun.COM These opinions are my own and no one elses, but you knew that didn't you.
