What kind of feedback are you trying to get?  If you just
want to know when two objects collide, you can just add a
collision handler:

At the moment it's not possible to get other information
about the collision, such as exact collision points, etc.

To get the current orientation of a limb (a subclass of Mobile),
use the Mobile method "get-rotation".
