A smart interactive toy comprises a shell, an interactive control module, a moving mechanism, and an anti-fall sensing module comprising a first signal sending unit and a signal receiving unit; the first signal sending unit is mounted on the shell, connected electrically with the interactive control module and used for sending a first sensing signal to the interactive control module when the signal receiving unit does not receives a first reflected signal, reflected after the first sensing signal meets an obstacle, in a predetermined time period, so that the interactive control module drives the moving mechanism to stop moving, thereby achieving that the user controls the smart interactive toy to avoid it from falling down a table or into a deep pit, which ensures that the toy can be interacted and is not easy to damage.

Described is a remotely controllable inflatable system. The system includes a base having at least one blower and at least one remotely controllable drive wheel. Notably, an inflatable form is connected with and sealed against the base. Activating the at least one blower causes the inflatable form to inflate. A user can then use a remote-control transmitter to cause the base with inflatable form to drive upon a ground surface.

A robot includes a body, a wheel having a ground contacting surface when moving, and a wheel drive mechanism that drives the wheel so as to advance from a housing space provided in the body to an exterior and withdraw. The wheel drive mechanism causes the wheel to withdraw to the housing space in a non-ground contacting state when a housing condition is satisfied. The body has a ground contacting bottom face that comes into contact with the ground when the wheel is housed in the housing space in a non-ground contacting state.

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.
