The present invention provides a walking device adapted to simulate a gait of a legged animal. The walking device includes a frame, a leg, an upper and lower rocking arms, a connecting rod and a crank all of which are axially interconnected together. The rocker arms and crank are axially mounted to the frame in a triangular spatial relationship. The cranking link is axially mounted to the frame in cooperative association with a suitable power source and operatively linked to a connecting rod which serves to transmit power from the crank to the interconnected linkages of the walking device. The leg has a hip joint at one leg end axially connected to the upper rocker arm, a foot attached to an opposite leg end and a knee joint axially connected to the connecting rod which is axially connected at an opposite connection rod end to a crank rod of the crank. The lower rocker arm at an end opposite from its axial frame mount is axially connected to a centrally disposed elbow linkage of the connecting rod. As power is supplied to the crank, the connecting rod reciprocates back and forth causing the foot of the leg to simulate an animal's walking gait. Multiple legged devices may be constructed by connecting a series (usually in pairs) of single legged units together. The device, through the proper location of various components, is able to simulate the gait of a legged animal in that the foot will travel along a substantially linear path until the device achieves a lifting position whereupon the leg is lifted and returned to a forward step similar to that of the legged animal. The walking device may be manually powered or motorized by applying motorized power to the crank axles.
