Abstract
The present invention pertains to a robot for moving along uneven terrain. The robot comprises a body having an opening through which a leg can pass. There is also a device for moving the body. The moving device includes at least 3 legs, at least one of which can exhibit an overlapping gait with respect to another leg. The robot is also comprised of a device for controlling the moving device such that the body moves along the terrain in a desired path. In an alternative embodiment, the moving device includes legs, each of which can exhibit an overlapping gait with respect to another leg while moving the body. In a preferred embodiment, each leg is comprised of a shoulder that is rotatable in a .theta. direction. Each leg is also comprised of a pedestal which has an axis that is disposed in essentially a z direction, where the z direction is perpendicular to the .theta. direction. There is also a device for linking the shoulder and the pedestal such that the pedestal can be moved in an r direction to a desired r position with respect to the shoulder, where the r direction is perpendicular to the z and the .theta. directions. The robot moves along the terrain which it defines with th…
