Abstract: A mechanical roping steer apparatus for practicing roping of a steer may comprise a support assembly for resting on a ground surface, a rotatable wheel configured to contact the ground surface such that movement of the support assembly across the ground rotates the wheel, and a steer assembly connected to the support assembly. The steer assembly may comprise a frame having a spine structure, a hip structure movably mounted on the frame to move between first and second positions, and a leg structure movably mounted on the hip structure to move between forward and rearward positions, and including at least one leg member. The steer assembly may include an actuation assembly may be configured to move the leg member downwardly toward the ground surface during rearward movement of the leg member and move the leg member upwardly during forward movement of the leg member.

Abstract: A miniaturized steer roping practice apparatus may comprise a mobile base comprising a frame, an axle rotatably mounted on the frame to rotate about a rotation axis in a forward rotational direction for forward movement and a rearward rotational direction for rearward movement, and at least one drive wheel mounted on the axle. The apparatus may further comprise at least one leg movable with respect to the base, a leg actuation assembly configured to move the at least one leg in conjunction with rotation of the drive wheel, a cover mounted on the mobile base and having an exterior surface with a resemblance to a steer, and a motivating assembly configured to drive the axle in the forward rotational direction using stored energy. The motivating assembly may be configured to store energy by rotation of the axle in the rearward rotational direction.
