[ODE] roboter arm

[Gazi Alankus]

But don't forget that the invisible bodies will have to have a certain
mass. Zero mass just does not work in ODE. If you don't assign any
mass to the invisible body, it's mass will end up being 1. So you
might want to keep this in mind and adjust their masses accordingly,
or you may look into using ball joints.
