I wonder where Chris Leger is these days -- mountain climbing somewhere?
Well, I'll jump in until higher authority can answer better.

The lower-level dynamics libraries for D2K can handle multiple
mechanisms, I think this includes collection detection *between* the
mechanisms.  If not, it will be simple to fix.

However, the bookkeeping is not there for multiple *robots* in the
higher-level robot-simulation code (built on top of the dynamics
libraries).  This is something I plan to try to help with very soon
since I need to start simulating multiple robots for my research.  I'm
hoping it won't be too hard, but lots of classes are connected in
different ways for paring the robots descriptions and starting the
simulation, and I'm not sure exactly how deep the assumptions underlying
a single robot run.  Chris Leger can probably answer much more easily,
since he wrote the code.
