But as soon as it strikes something solid—when a walking robot’s foot hits the ground, or a grasping robot’s hand touches an object—those equations break down. Roboticists typically use ad hoc control strategies to negotiate collisions and then revert to their rigorous mathematical models when the robot begins to move again.

Meet the 6-legged robot lizards that may one day roam MarsWheels are great for traversing flat, paved surfaces, but when the terrain is covered with loose sand and large rocks, it’s time to grow feet. Scientists built a six-legged robot after studying the movements of lizards, and the breakthrough may mean a fast walking rover we send to Mars that’ll leave its predecessors in the dust…
