Problems solved by technology

[0004] At present, most robot control systems based on voice recognition can only simply recognize some basic commands such as "forward", "turn left", "stop", etc., even if there are a small number of robot control systems that can realize continuous voice recognition , and can only recognize robot control commands in a fixed pattern, which is far from the expected intelligent voice control of robots

Embodiment

[0067] A robot control method based on natural language understanding of this example, as attached figure 1 shown, including the following steps:

[0068] S1. Acquiring and analyzing voice signals;

[0069] S2. Understanding user intent;

[0070] S3, controlling the movement of the robot.

[0071] Said step S1 comprises the following steps:

[0072] The operator issues a series of continuous voice commands through the microphone, the microphone acquires the voice signal and turns it into a voice stream, and the computer receives the voice stream and converts it into a digital signal that the computer can process. After the voice signal is digitized, it can be reflected as a waveform diagram to intuitively represent its digital characteristics. First, the voice signal is preprocessed through steps such as pre-filtering, sampling, A / D conversion, framing, data windowing, and high-frequency boosting. Since the obtained speech signal and the reference template have different l...

Abstract

The invention provides a robot control method based on natural language understanding, and the method comprises the steps: (1) acquiring a speech signal and converting the speech signal into a corresponding digital signal, and then converting the digital signal into corresponding text information through a dynamic time warping algorithm; (2) establishing a model, and carrying out the matching of the key information and redundant information contained in the text information, obtaining a segmentation result of the text information, and then classifying the text information through a classifierestablished through a maximum entropy model, and then converting a control instruction to be converted further in the classification result; (3) carrying out the reverse solving of the obtained spatial coordinates of a tail executor of a mechanical arm into a joint variable of a rotating joint through a robot control command, and controlling the robot to move.

Description

technical field [0001] The invention belongs to the field of robot motion, in particular to a robot control method based on natural language understanding. Background technique [0002] With the increasing intelligence and flexibility of robots, traditional robot control methods have gradually been unable to meet the needs of intelligent robots. Therefore, finding a suitable intelligent control method for robots has become a current research direction. Through the intelligent control method, the robot only needs to understand human intentions, and complete the rest of the control work through its own intelligence. [0003] Nowadays, with the development of computer technology and speech recognition technology, speech has been gradually accepted by people as one of the ways of communicating with computers. As a common way of communication between people, voice is more convenient than mouse and keyboard. Therefore, voice has become one of the intelligent control methods of ...
