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.

Host applications of modular assembly system

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.

Firmware of modular assembly system

A system includes multiple assembly modules and one or more connectors. Each assembly module includes at least one connection interface, and each connector includes two open ends adapted to fitting into the connection interfaces of the two assembly modules, respectively. Each connector is configured to mechanically and electrically connect two of the assembly modules via the respective connection interfaces of the two assembly modules. The assembly modules include at least a control module having a communication unit and a processor. The communication unit is configured to obtain a set of host instructions from one or more hosts. The processor is configured to generate a set of operation instructions for each assembly module based on at least the set of host instructions.

Modular assembly system

A method for registering one of a plurality of assembly modules operatively coupled to one another in a modular assembly system is provided. A first message including a first identifier of the assembly module is received from one of the plurality of assembly modules. A second message including a second identifier for the assembly module is transmitted to the assembly module. The second identifier is generated based on at least the first identifier. A third message including the second identifier is received from the assembly module. In response to determining that the third message is received, the assembly module is registered as a new assembly module of the modular assembly system. At least one of the receiving, transmitting, determining, and registering is performed by a control module of the plurality of assembly modules.

Modules registration and status update of modular assembly system

Connector for a robotic module

A toy construction set includes first and second construction elements, a pin, and a fastener including a body and a head. Each of the first and second construction elements includes through-holes and grooves on two major surfaces, respectively, of the construction element. A thickness of each groove is substantially the same. At at least one end of each groove, an edge of the groove is curved. The pin includes a body having a cavity and a member. A first portion of an edge of the member is curved, and a second portion of the edge of the member is straight. A thickness of the member is not larger than the thickness of each groove. The member of the pin is fixed in place in one of the grooves of the first construction element when the first and second construction elements are coupled by the pin and the fastener so as to constrain the pin from rotating with respect to an axis of the body of the pin.

Robotic 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. 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.
