  • Micro robot
    Patent number: 6520272
    Abstract: A micro robot includes first and second masses, each having a first contact surface having a first frictional coefficient and a second contact surface having a second frictional coefficient and formed to be inclined by a predetermined angle with respect to the first contact surface, the first and second contact surfaces being formed at the lower portion of the mass corresponding to a surface of a target object, and an actuator provided between the first and second masses for periodically changing the distance between the first and second masses and enabling the first and second contact surfaces of the first and second masses to selectively contact the surface of the target object in synchronization with a periodic change in distance between the first and second masses.
