Abstract: A modular device includes a polyhedral building element having a first type connector and a number of second type connectors; and a main control module comprising a plurality of second type connectors. The first type connector and the second type connectors are disposed on side surfaces of the building element. One of the second type connectors of the main control module is used to magnetically connect with the first type connector of the building element so as to detachably connect the building element to the main control module. The first type connector includes a first detection circuit, and each second type connector includes a second detection circuit.
