[ODE] Steering A Vehicle (AMotors)

[Jeff Weber]

I agree, i'd prefer to not set it directly, but the only way to do the 
steering with the Hinge2 joint that I could see was by using the dParamVel 
and dParamFMax parameters.  At first glance, I didn't think this would work 
well for taking input from a desk mounted steering wheel, but I guess it 
could be made to work.

Has anyone done this before?

Hi Jeff,

I haven't done any wheeled vehicles with ODE yet, but the hinge-2 joint is 
especially well suited to use for driving and steering, according to the 
documentation. I'm not sure if the AMotor would be better or worse. In any 
case, if you intend to set the steering angle directly, then you have no use 
of the AMotor at all because you'll be taking over its job "manually". 
However, I don't think you should set it directly, because it can lead to 
all kinds of inconsistencies or instabilities, basically because you are 
bypassing the simulated "laws of physics" as imposed by the ODE system.

Greets,
Mark
