And you do of course know about the following tools:
http://playerstage.sourceforge.net/index.php?src=gazebo
http://www.pyrorobotics.org/?page=The_20Pyrobot_20Simulator
They are Robot simulation environments, I think most of them use ODE.
I know there are a few more, but I couldnt recall the names of them right now...

Hi Harald (and others),
I am very much involved in physics engines for games and virtual reality,
and as far as I know all physics engines come with optimized collision
detection (optimization is a key feature because it is really greedy). I
don't know exactely what you mean by "simulation" but if it is dynamical
simulation you should have a look at http://www.ode.org/ which is the best
free dynamical simulator I know - though it is far behind its commercial
counterparts. It includes proper collision detection and polyarticulated
rigid bodies dynamics.
Another point: in most well written applications, physics (for the
simulation of your robot) and rendering are isolated layers. Different
functions, different packages... That makes sense and is worth keeping for
general understanding of the architecture.
