Hi folks...

I started working with ODE some time ago. But I encounter some problems =
on understanding the manual and all the "how to model my stuff witrh =
ode" subject.
Thus I will briefly describe my problem. Maybe someone can comment on =
that:

I want to model some kind of bug robot.For the start, it shall have the =
follwoing structure:
H : hinge
T : Thorax (CCylinder)
L : Leg (Box)

L H L H TTT H L H L
        TTT
        TTT
L H L H TTT H L H L
        TTT
        TTT
L H L H TTT H L H L


(One Body, six legs, each leg consisting of two parts and connected by =
two hinges)

In the final state I'd like to say something like:
Hinge 1 bow 10 degrees.

So do I have to attach Motors to the hinges to achiev this (I did not =
quiet figure out how this could work) or do I have to use these =
Transform geometries and rotate them (I I understood them right they can =
be used to rotate for example a leg around one of its ends)


Well, you see, I not quiet used to the subject. But maybe someone could =
help me getting it :-)
Perhaps someone has done something liek that, or someone could provide =
me some example code...

Thanx a lot,=20
mike.
