The invention is a robotic bird that uses flapping flight for lift and propulsion. The bird has a body, two wings, tail and head with a beak in addition to on-board electronics and batteries. Each wing is controlled separately by four motors. One motor controls the flapping, one the angle of attack (wing tilt), one the degree of morphing and folding of the wing and one the horizontal motion of the wing. The tail is controlled by three servomotors, one for up and down motion, one for tilting and one for spreading the tail feathers. Thus, the bird has 11 degrees of freedom in total in its wings and tail. This design allows the use of evolutionary methods for teaching the bird to fly in a much more efficient way than has previously been possible.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

A toy road paving device (toy dispenser) is provided that simulates a real-world road paving machine by dispensing, laying down, cutting, and smoothing either one or multiple strips of spooled tape material upon a hard, flat surface such as a table or floor. The device “paves” the tape road easily, smoothly, evenly, and without the risk of tearing the tape material from excess stress. More generally, the device can lay out any toy play surface printed on tape, a strip of paper, or other material. The device can be operated manually or mechanically powered.

An action robot may include a main body, at least one joint, and at least one limb configured to be rotatably connected to the main body via the joint. The joint may be configured to provide elastic force in a direction in which the limb is unfolded or pulled away from the main body and a wire connected to the limb to pull the limb in a direction in which the limb is folded or pulled toward the main body. The wire may be connected to an elevation rod provided inside the main body. A drive assembly may be provided outside the main body and be configured to lift the elevation rod. A rod spring may be provided and configured to provide a downward elastic force to the elevation rod. A wire support provided within the main body may be configured to support the wire.
