Lisa,
Thanks for the pointer...its been useful to see how you created a
multi-robot world (much easier than what I'd been doing).
I now have a question about how you compared robots for your
subsumption robots finding lights in various flavors of room lab.
One approach would be to put students robot brains into the same room
and see which one finds the light first. But that adds a new
complexity to the problem that the students wouldn't have explicitly
planned for. As an alternative, I tried to run two pyrobot simulators
at the same time, one running each robot. But I then ran into socket
address complaints. My current thinking is to increment a counter for
each update call, and to compare based on the total number of steps
each robot has.
Any other ideas?

Belinda,
I am teaching an introductory cognitive science class this semester
and came up with a fun Braitenberg world. It is based on an example
from the "Understanding Intelligence" book, where what they call
"helping behavior" emerges. It doesn't quite work the same way in
simulation, but still leads to some interesting interactions.
There are three robots all attracted to light, with light sensors on
their fronts. Two of the robots have light emitters on their backs.
Plus there is also a light in the environment.
You can see the lab here:

Near the bottom of this page there are some links to the code you'd
need to run this example.

Hi,
I'm wondering if any of you have written some flashy looking
Braitenberg simulations via Pyro.
I've tried out individual Braitenberg brains in various worlds,
but the behaviour isn't so interesting when there's not several
robots of different types interacting. For a peek at collective
behavior, I found:
http://people.cs.uchicago.edu/~wiseman/vehicles/
but the code is not available. The Understanding Intelligence
book also provides a simulator at:
http://www.ifi.unizh.ch/groups/ailab/people/lambri/mitbook/
braitenberg/braitenberg.html
but the images look clunky and there's some glaring bugs.
Pyro has such a nice feel to it. I'd love to create some worlds
of similar quality to the ones shown in the wiseman links, but
figured I'd poll you all to see if anyone has already done this.
Also a question: is there a rule of thumb for how many robots can
I put into a world before the CPU bogs down?
Thanks,
