[ODE] Some hints required(involvind attaching objects)

[DjArcas]

If I were you, I would cheat, and have the 'gripper' as a magnet, or
something sticky. I wouldn't like to try and 'wedge' an object in place by
squeezing it between two other objects.

It only has to LOOK like it's gripping the object. :)
