Abstract: 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.
