A modular assembly toy system includes assembly modules each including at least one connection interface and one or more connectors each configured to mechanically and electrically connect two of the assembly modules via the respective connection interfaces. The assembly modules include a control module and an analyzing module. The control module includes a control module communication unit configured to obtain a set of host instructions from one or more hosts and a control module processor configured to generate a set of operation instructions for control each assembly module based on at least the set of host instructions. The analyzing module includes an analyzing module sensor configured to obtain a sensor signal, an analyzing module processor configured to analyze the sensor signal to generate a first analyzing result, and an analyzing module communication unit configured to transmit the sensor signal or the first analyzing result to at least one of the hosts.

A remote-control aircraft comprises an aircraft body with a mounting platform provided with a connecting part and first magnet(s), and the connecting part is perforated with a connecting hole; and comprises an aircraft wing with an inserting part and second magnet(s) on its underside close to the aircraft body, the inserting part is rotationally inserted into the connecting hole, the second magnet and the first magnet are connected by magnetic attraction, and the aircraft wing is in close contact with the mounting platform. Thus, the aircraft wing and body can be quickly assembled and disassembled and can be carried conveniently. While the aircraft wing collides with an obstacle, it can be rotated around the inserting part as the center, and the impact force can be unloaded by rotating to prevent the aircraft wing from being damaged and prevent the aircraft wing from being separated from the aircraft body.

A connection structure includes two connection interfaces and a connector. Each connection interface includes planar contacts arranged at a center and one or more concentric rings on a circuit board and first lock mechanisms arranged on a first casing. The connector includes a second casing including two open ends and second lock mechanisms arranged on the second casing and pins. Each pin includes two ends each exposed by one of the two open ends of the second casing, respectively. When the connector is plugged into the two connection interfaces at orientations relative to one another, the pins of the connector are in contact with the planar contacts of each connection interface so that the two connection interfaces are electrically connected, and the second lock mechanisms of the connector are interlocked with the first lock mechanisms of each connection interface so that the two connection interfaces are mechanically connected.

An inflatable toy plane assembly is provided. The plane assembly includes inflatable wings, an inflatable fuselage, an inflatable empennage (tail area stabilizers), and/or other inflatable elements. Not all elements of the inflatable plane assembly are required to be inflatable, e.g., the wings may be inflatable, and the fuselage may not. The plane assembly preferably includes one or more valves to facilitate the inflating and deflating of the plane's inflatable elements. In use, the inflatable plane assembly is deflated for compact storage (e.g., rolled up) and subsequently inflated when preparing the assembly for flight. The plane includes detachable wings and/or detachable tail stabilizers that are detached for storage, and subsequently reattached to the plane's fuselage and inflated for use.

A device with a plurality of attachments for a beverage can which enhance the aerodynamics of the beverage can, comprising a base assembly adapted for attachment to a beverage can and a nosecone adapted for attachment to a beverage can. The base assembly further comprises a basal member, a peripheral sidewall, a guide unit, a central aperture, and a plurality of stabilizing units. The basal member further comprises an inner surface configured to follow the contour of a beverage can. The inner surface of the basal member contains a central aperture. The central aperture is surrounded by a divergent thrust nozzle, which focuses the beverage contents and increases the pressure of the liquid rivulet that is released. The heightened pressure of the beverage contents increases the thrust of the rocket during launch beyond what the thrust would be in the absence of the thrust nozzle.

Disclosed here are systems for detachable airframe components including detachable nose cones, propeller assemblies and motors. In some example embodiments, the assemblies include a nose cone with a connection receiver, a motor assembly with a rotatable section, where the rotatable section includes torque arms configured to secure with the nose cone connection receiver, and a propeller assembly, configured to connect to the nose cone.

Remote control aircraft may benefit from airframes with components that are easy to connect and disconnect. For example, during repair, storage, or transport, it is beneficial to disconnect a wing from a fuselage of a remote controlled aircraft. Systems and methods for connecting and disconnecting airframe components are described herein. For example, a snap-fit mechanism is used in some instances to provide a solid connection during operation or flight, and also to quickly and easily disconnect components at various times, such as during repair, storage, or transport. The snap-fit mechanism allows for a quick disconnect without the use of tools and without causing any loose parts.

A method for updating firmware on a control module of a modular assembly system is provided. Information related to noise sampled from the control module is obtained. A first encryption key is calculated based on the information. Firmware to be updated on the control module is received from a host of the modular assembly system. The firmware is encrypted based on at least a second encryption key. In response to determining that the received firmware can be decrypted, the decrypted firmware is loaded into the control module. At least one of the obtaining, calculating, receiving, determining, and loading is performed by the control module.

A connection structure includes two connection interfaces and a connector. Each connection interface includes planar contacts arranged at a center and one or more concentric rings on a circuit board and first lock mechanisms arranged on a first casing. The connector includes a second casing including two open ends and second lock mechanisms arranged on the second casing and pins. Each pin includes two ends each exposed by one of the two open ends of the second casing, respectively.

A method for providing host instructions to a control module of a modular assembly system is provided. A graphical programming environment including sets of first and second graphical representations is presented to a user. Each first graphical representation corresponds to a statement block comprising a parameter. Each second graphical representation corresponds to one of assembly modules associated with a property. A user is facilitated to select at least one of the first graphical representations and provide values to the parameter of each selected first graphical representation. The user is facilitated to provide values to the property of one or more of the second graphical representations. Based on at least the selected first and second graphical representations and the provided values thereof, a set of host instructions are generated. The set of host instructions are transmitted to the control module for controlling operation of the assembly modules.
