A modular robot system includes N (N is an integer that is 2 or greater) cube-type unit robots, each of the N cube-type unit robots comprising: a housing in the shape of a regular hexahedron; a step motor installed in the housing; and a controller installed in the housing and for controlling the step motor. The housing has, on one surface thereof, a mounting groove in which a rotary body rotating by means of a rotating shaft of the step motor can be mounted, and, on the other surface of the housing, a connection groove in the same shape, so that by means of a connector to be mounted in the connection groove, connection to another cube-type unit robot is possible, and the housing has identification marks with different shapes from one another on the respective surfaces thereof.
