Abstract: A calf roping training apparatus incorporating a simulated calf, a support column and a towing structure. The support column has a spin joint and an invert joint. The calf body of the simulated calf is formed by one or more pieces of simulated skin and a simulated head fixed in anatomical form by a body frame. The support column is anchored to the towing structure. The towing structure has a tow member, a pair of long skids, a short skid, and a towing attachment device. The support column base is attached to the short skid which provides for transfer of the weight of the simulated calf to the ground. The support column top is attached to or integrated with the body frame.

Abstract: A multi-legged walking device includes a crankshaft, a plurality of linkage bar mechanisms, a support member, and a driving device. The crankshaft includes a plurality of main journals and crankpin journals. The plurality of linkage bar mechanisms is spaced from and substantially parallel to each other. The linkage bar mechanisms include a plurality of frames. Each frame is rotatably connected to one of the plurality of main journals. Each linkage bar mechanism includes a connecting bar, a first rocker, a second rocker, and a leg. Two ends of the connecting bar are rotatably connected to one of the crankpin journals and the leg. Two ends of the first rocker are rotatably connected to one of the plurality of frames and the leg. Two ends of the second rocker are rotatably connected to one of the plurality of frames and the connecting bar. The support member is fixed to the frames.
