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.
