ABSTRACT:
A robotic leg for traversing a path similar to that of a human leg during walking on a floor. The leg includes a housing, a wheel, a rail, a slide shaft, a follower, and a leg. The leg takes a step by rotating a shaft, causing the wheel to rotate, causing the slide shaft to pivotally move with the wheel, causing the slide shaft to slide down the follower, causing a plurality of outer roller bearings and an inner roller bearing to roll along a convex periphery of the rail, causing the follower to move along the convex periphery, causing a hip end of the leg to pivot forwardly about an inner roller pin, and causing an uppermost pair of flat rods of the leg to pivot forwardly about their midpoints. The leg rebounds from the step by continuing to rotate the shaft, causing the wheel to continue to rotate, causing the slide shaft to continue to pivotally move with the wheel, causing the slide shaft to slide up the follower, causing the plurality of outer roller bearings and the inner roller bearing to roll along a straight periphery of the rail, causing the follower to move along the straight periphery, causing the hip end to pivot rearwardly about the inner roller pin and causing the uppermost pair of flat rods to pivot rearwardly about their midpoints.
