Hello,
I'm trying to implement a simulated omnidirectional robot which has
three wheels each attached to an rotational leg behind the chassis.
It has three legs that can be turned by a motor so that the robot can
drive to any direction instantaneously.
The wheel is also attached at the end of the leg and can turn by itself.
Does it make sense to you?
Now the problem is that I want to define the wheel as a child of each
leg as it can be a parent of the wheel.
However, the Corobot 4 wheeled robot example in the book I'm trying to modify, didn't make the wheels has child-parent relation to the body intentionally. But I still don't know why is it make sense.
So here goes my question.
How can I change the wheel as a child of each leg?

Sorry about my poor explanation.
Please give me any comments, ;)
Thanks,
