With cameras and GESTALT, it's similar to giving the rovers "eyes" and a brain to access the local terrain and identify any possible hazard.

Currently on the two rovers that are operating on Mars, they have nine cameras on board. These include four hazard avoidance cameras, two navigation cameras, two panoramic cameras and one science microscopic imager.

Now try the (close eye walking) experiment before to get a feeling of what is improved, but this time open your eyes after 2 steps, re-access the surroundings again and make two more steps. I think you would agree that this is much easier and therefore safer. Now that the rover is available to analyze the area, the next step is to move to the given location. To accomplish this, it is important to study the vehicle kinematics, this allows us to estimate how much wheel rotation and steering angle is required to achieve the desire movement.
