Object collision animation

Hi All,

I’m wondering if it’s possible to use Kangaroo to animate some simple crash collision?
example bellow, I want the big red box to crash into the smaller boxes and scatter them.
I’ve use the example file from Daniel Piker, and added a box that I can move with a slider, but small boxes doesn’t really react to the moving box.

The main application I’m thinking of is animating robotic toolpath, to visually display pick and place results, and collision (if any)
