The ODE collision system generates forces based on relative 
velocities, bounciness, and penetration depth. Basically, the 
idea is to add opposing forces that drive the objects out of 
each other in one time step.

However, you can use ODE with animation. Just make the animations 
turn into forward kinematic forces, rather than absolute joint 
position/orientations. This makes the right thing happen if you 
run into a joint, etc.
