One of our typical scenarios, here at the LAAS is this one:

Two (outdoor) robots (one drone, one UGV), in a zone with vegetation and 
some sparse buildings.

The drone perceive the environment with a stereocamera and create a 
traversability map that it sends back to the UGV. The UGV uses it to 
plan its trajectory and move in the zone.

We need the physical simulation to get a more realistic behaviour of the 
UGV when it moves.

In other scenarios (like join manipulation of objects), physics are even 
more important for us.

If needed, I can get into more details or give other examples.

Cheers,
Severin
