A self-propelled device includes a spherical housing and an internal drive system. The self-propelled device can further include an internal structure having a magnet holder that holds a first set of magnets and an external accessory comprising a second set of magnets to magnetically interact, through the spherical housing, with the first set magnets

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 aeronautical vehicle that rights itself from an inverted state to an upright state has a self-righting frame assembly has a protrusion extending upwardly from a central vertical axis. The protrusion provides an initial instability to begin a self-righting process when the aeronautical vehicle is inverted on a surface. A propulsion system, such as rotor driven by a motor can be mounted in a central void of the self-righting frame assembly and oriented to provide a lifting force. A power supply is mounted in the central void of the self-righting frame assembly and operationally connected to the at least one rotor for rotatably powering the rotor. An electronics assembly is also mounted in the central void of the self-righting frame for receiving remote control commands and is communicatively interconnected to the power supply for remotely controlling the aeronautical vehicle to take off, to fly, and to land on a surface.

An electronic device including a first device having a spherical housing, and a second device arranged on a surface of the spherical housing, wherein the first device includes a first driving device arranged in the spherical housing and configured to deliver power to the spherical housing, a structure arranged in the spherical housing and configured to arrange the second device on a surface of the spherical housing, a second driving device configured to trigger a movement of the structure, a processor electrically connected with the first driving device and the second driving device, and a memory operatively connected with the processor, wherein the memory is configured to store instructions that, when executed, enable the processor to control the second driving device to, in response to identifying a coupling of the second device with the first device, adjust an arrangement direction of the second device with respect to the first driving device.

The present invention relates to a power transmission apparatus for transmitting power between components, and a built-up type toy including the same. The power transmission apparatus comprises: a housing having an operating space formed therein; a connection hole that is open in at least one direction of the housing; a gear assembly that operates in the operating space of the housing and has a connecting link on one end thereof which is exposed to the outside through the connection hole; and a coupling tube for selectively interconnecting two connection holes of the power transmission apparatus and a counterpart power transmission apparatus connected thereto, wherein the connecting link of the power transmission apparatus and a counterpart connecting link are connected and interworked with each other in the interior of the coupling tube.

A self-propelled device is provided including a drive system, a spherical housing, and a biasing mechanism. The drive system includes one or more motors that are contained within the spherical housing. The biasing mechanism actively forces the drive system to continuously engage an interior of the spherical housing in order to cause the spherical housing to move.

A traverse and elevation mechanism and a toy robot using the mechanism. The mechanism is placed in a rollable spherical housing and includes two cams and cam follower that adjust radial and angular positions of an internal magnetic element. The internal magnetic element is magnetically attracted to an external magnetic element such that movement of the internal magnetic element moves the external magnetic element.

A robot including a spherical housing made up of a main housing portion, a first spherical cap portion, and a second spherical cap portion. The main housing portion is disposed between the first spherical cap portion and the second spherical cap portion. The robot further including a weight that is provided in the main housing portion and configured to rotate around a pivot that is orthogonal to a shaft connecting the spherical cap portions. When outputting a response to an input instruction received from a user, via an input device, based on a predetermined processing is determined to require a predetermined time or more, a robot controls a first drive mechanism during the predetermined processing such that the first drive mechanism rotates a weight around the pivot to reciprocally move the weight in the opposite directions of the pivot.

The present disclosure provides a child-mother toy, including: a first assembly and a second assembly. The second assembly includes a supporting member, a triggering subassembly, a unfolding subassembly and an ejection subassembly, and the triggering subassembly, the unfolding subassembly and the ejection subassembly are disposed to the supporting member. Before the triggering subassembly is triggered, the unfolding subassembly is folded at the supporting member so as to define an accommodating cavity together with the supporting member, the accommodating cavity is configured to accommodate the first assembly therein; and after the triggering subassembly is triggered, the unfolding subassembly is unfolded to open the accommodating cavity, and meanwhile the ejection subassembly ejects the first assembly out of the accommodating cavity.
