That's one of the reasons why a programmer goes to all the trouble (and
fun?) of building a physical model of a bot instead of dealing with
over-acurate 3D CG simulations.
Ok, now for the Positioning system debate. Just one word: *Ants*
They're blind. The advantage they have is chemical sensors (smell).
I think they use a mix of "(chemical) line" following and landmark system
(or line node recognition)
My robotic vision project will, hopefully, evolve to something that can be
used as a landmark/graphic pattern recogniser to be used in the bot
positioning area.

PS: MyProjectsUpdate:
My Robotic Vision project (using http://www.ccs.neu.edu/home/psksvp dll's)
and my Sanscript & Spirit.OCX project (http://www.trulyvisual.com) have all
stalled temporarily. I was expecting this already, 'cause this time of the
year my workload doubles, so no spare time :(
..best guess is March, to continue with both projects.

| Hi Marco, Building the robot is definitly fun. But I was really suprised when I built two robots from the same design, ran the same "GO" program in them and they moved differently! 8^o I'm glad to find another ant lover here!
