A modularized personal robot belongs to the robot field. The invention includes a sensing module, a control module, a drive module and standard interface modules. The sensing module and the control module are connected by a second standard interface module, and the control module and the drive module are connected by a first standard interface module. The sensing module is fixed on the second standard interface module; one end of the control module is fixed on the second standard interface module, the other end thereof is fixed on the first standard interface module; the drive module is fixedat the other end of the first standard interface module; and the whole robot is driven to move by the drive module. After analyzing the functional characteristics of the robot, the invention designs the modularized personal robot according to the task requirements of the personal robot. The robot is composed of four functional modules, which facilitate the upgrade and the extension of the functions of the robot; the assembly, the replacement and the maintenance are rapid; and the production cost is reduced. Since the modularized structure is adopted, the volume production can be realized.
