A multi-functional service robot comprises, sequentially mounted in a combined manner, a head portion, a trunk, a base, a human-computer interaction module, a wireless communication module, a mobile control module, a charging module, an obstacle avoidance and cruise module, and a main control module. The human-computer interaction module is used for human-computer speech interaction, video interaction, and text information interaction. The obstacle avoidance and cruise module is used to scan a surrounding environment of the robot, acquire surrounding obstacle information of the robot, and transmit the same to the main control module, so as to allow the main control module to generate a control signal. The mobile control module is used to receive the control signal transmitted by the main control module, and drive the robot to travel according to the control signal. The charging module is used for autonomous charging. The multi-functional service robot greatly improves an interactive learning ability and a knowledge -update ability of a robot, thereby interacting well with a user, improving user experience, and meeting user requirements.
