Re: 4WD Turning Difficulties

I think a rear steering system will have drastically less turning ability than a front steering system. With a front steering system, all the non-steering wheels are behind the steering wheels, so they will follow them. In a rear steer system, I think that the non steering wheels being in front and behind the steering wheels will reduce the turning ability, and lead to awkward handling characteristics. Take this with a grain of salt though, I am having a little difficulty imaging a rear steering robot with a trailer turning, so I'm probably missing something.
