I saw a video of the mars rover curiosity turning in place. It seemed really stable by turning its wheels it was able to easily reorient itself even on a slope while not moving forward. This made me think back to a lot of the odd track patterns in rover pictures.
My main question is:
Does the rover have to be stationary to change direction? Or can it turn and move like a car? If it can- what's the maximum degree it can turn while in motion? I'm sure they have something in place to avoid hairpin turns. If it can't- what was the reason behind this design choice? Stability?
