Watch this 2-legged robot conquer an obstacle course

An unsupported bipedal robot can now walk down steep slopes, through a thin layer of snow, and across astroturf littered with obstacles. The robot’s feedback control algorithms should help other two-legged robots—and powered prosthetic legs—gain similar capabilities. “The robot has no feeling in her tiny feet, but she senses the angles of her joints—for instance, her knee angles, hip angles, and the rotation angle of her torso,” says Jessy Grizzle, professor of electrical engineering and computer science and of mechanical engineering at the University of Michigan. “It’s like walking blindfolded and on stilts.” MARLO is Grizzle’s first robot that can walk (and fall) in any direction, known as 3D walking. For a previous robot, MABEL, researchers produced leading control algorithms for robots that need to move in only two dimensions. MABEL was attached to a boom that gave her sideways stability.
