When a robot is moving one of its limbs through free space, its behavior is well-described by a few simple equations. 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.
Wheels 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…
We understand the challenges robotics classrooms face every day in terms of cost, number of robots, batteries, and homework. That [...]
In one of the earliest experiments using a humanoid robot to deliver speech and physical therapy to a stroke patient, researchers saw notable speech and physical therapy gains and significant improvement in quality of life.
