Abstract

The invention relates to a robot autonomous sensing head system, belongs to the technical field of robot control, and solves the problem that an existing robot head cannot be autonomously sensed and controlled. Comprising the steps that a pickup sensor collects a voice signal, and the voice signal is sent to a calculation unit through a pickup sensor control panel; after noise of the voice signal is removed by the calculation unit, the voice signal is converted into an initiating text, the initiating text is transmitted into a large language model and an emotion classification model to obtain a response text and emotional probability distribution of the initiator, and the response text is converted into response voice through a voice generation model to be fed back to the voice synthesis sensor; and according to the sentiment probability distribution of the initiator, calculating the sentiment category of the responder, and then feeding back a corresponding expression output instruction to the expression panel, the voice synthesis sensor receives and plays the response voice; and the expression panel displays the expression according to the received expression output instruction. And flexible autonomous control and perceptual interaction of the robot head are realized.
