Module system, module based robot system, and update method for module system

An update method for a module system comprising a plurality of modules connected to each other over a network to perform a data communication, the update method comprising:

• receiving, by a master module of the module system, update data corresponding to a target sub-module among at least one sub-module of the module system from an external device the master module including a bus pin, and each of the at least one sub-module including a bus pin for the data communication;
• transmitting, by the master module, the update data to the target sub-module;
• and
• performing updating, by the target sub-module, based on the received update data,
• wherein each of the master module and the at least one sub-module has a surface, and the surface of one of the master module and the at least one sub-module is detachably attached to the surface of another of the master module and the at least one sub-module by a magnetic force applied by a magnet of the master module or the at least one sub-module, and
• wherein the network includes the bus pin of one of the master module and the at least one sub-module being electronically coupled with the bus pin of another of the master module and the at least one sub-module by the magnetic force applied by the magnet of the master module or the at least one sub-module.

A module-based robot system comprising a plurality of modules communicating with each other, the module-based robot system comprising:

• a master module configured to communicate with an external device, the master module including a bus pin;
• at least one sub-module connected to a network to perform a data communication with the master module, each of the at least one sub-module including a bus pin for the data communication;
• and
• a power source module electrically connected to the master module and the at least one sub-module, to supply power to the master module and the at least one sub-module,
• wherein the master module is configured to transmit update data to a target sub-module among the at least one sub-module via the network, and data associated with an operation of the target sub-module is to be updated based on the update data,
• wherein each of the master module and the at least one sub-module has a surface, and the surface of one of the master module and the at least one sub-module is detachably attached to the surface of another of the master module and the at least sub-module by a magnetic force applied by a magnet of the master module or the at least one sub-module, and
• wherein the network includes the bus pin of one of the master module and the at least one sub-module being electronically coupled with the bus pin of another of the master module and the at least one sub-module by the magnetic force applied by the magnet of the master module or the at least one sub-module.
