The invention discloses a robot function configuring system, method and device, and belongs to the technical field of robots. The system comprises a server, a robot assembly and at least one piece of external equipment, wherein the robot assembly at least comprises a robot; the external equipment is connected with the robot; the robot assembly is configured to acquire equipment information of the external equipment, and send a configuration request relevant to the equipment information to the server; the server is configured to determine a configuration program corresponding to the equipment information after receiving the configuration request, and transmit the configuration program to the robot; the robot is configured to receive the configuration program, and finish configuration by using the configuration program; and the configured robot is used for executing a function limited by the configuration program. Through adoption of the robot function configuring system, method and device, the problem of resource waste since certain equipment built in a robot body is idle when function demands of a user on the robot are mismatched with functions provided by the robot is solved, and the effect of increasing the equipment utilization rate is achieved.
