I plan to try this myself once I test the robot controllers in simulation.
In "Reactive Visual Control of Multiple Non-Holonomic Robotics Agents,"
the CMU team says that they use a frame grabber with frame rate transfer
from a 3CCD camera. A 166mhz Pentium is used for the image processing.
I found this paper at
http://www.cs.cmu.edu/afs/cs/user/kwunh/www/pubs/visual-control.ps
I'm wondering how well one IR tower will communicate with multiple RCX's.
I haven't played with this yet as I haven't purchased the additional
equipment. Actually, I haven't played with the single RCX I have, at this
point. I plan on running all the controllers on a PC and beaming a
command stream each time step into the "play area." The command for each
individual robot will be preceded by its ID number.

| I realise this is an open ended question but I will ask anyhow. We (as I have mentioned a number of times, probably maing in RCX newsgroup) have 6 RCX's that we wish to make into a demo for school kids. Ideally that demo would involve some sort of (...)
