Claim 10:
11. A modular device comprising:
a master building element;
a plurality of slave building elements;
one or more processors;
a memory; and
one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by, the one or more processors, the one or more programs comprises:
instructions for setting ID numbers of all of the slave building elements to be a preset ID number after disconnecting the slave building elements from the master building element; and
instructions for assigning new ID numbers to slave building elements of N tiers that are connected to one output interface of the master building element in an order from first tier to Nth tier, wherein the slave building elements of the first tier are slave building elements that are directly connected to the output interface, the slave building elements of the Nth tier are slave building elements that are indirectly connected to the output interface through slave building elements of a (N−1)th tier, N is a natural number greater than 1;
wherein each of the master building element and the slave building elements comprises:
a first type connector comprising M first magnets, a first ground terminal, a first detection terminal, a first power terminal, and a first signal terminal;
L second type connectors, each of the second type connectors comprising Ni second magnets that are magnetically attractable to the first magnets, N second around terminals, O second detection terminals, P second power terminals, and a second signal terminal, where M, N, O, and P are natural numbers and at least one of M, N, O, and P is greater than 1;
wherein when the first type connector of a first of the master building element and the slave building elements is mechanically connected to one of the second type connectors of a second of the master building element and the slave building elements by the first magnets and the second magnets thereof, the first ground terminal, the first detection terminal, the first power terminal and the first signal terminal of the first type connector of the first of the master building element and the slave building elements come into contact with one of the second ground terminals, one of the second detection terminals, one of the second power terminals, and the second signal terminal of the second type connector of the second of the master building element and the slave building elements.
