Missions to the Moon have used wheels to get around. Makes sense if you're on a perfectly smooth terrain of powdery regolith. But we know the surface can be rocky and crater-filled, a terrain that might be best explored by a four-legged walking robot. In a new paper, researchers explain how the gait of the robot changes its ability to do science. Fast-walking robots let you cover a lot of ground, while a slower gait senses the ground's structure with every footstep.
