Problems solved by technology

[0005] At present, the research on humanoid robot dance is still at the stage of artificial choreography. The process is that a complete set of dance movements is pre-designed by humans according to the selected music, and the program for realizing the dance movements is written, and then the robot follows the established instructions. Performing, the robot does not

[0113] 1. Positive number: [50][186]=0.1256, stored as 501860.1256

[0114] 2. Negative numbers: [50][186]=-0.1257, stored as 501862.1256

[0115] 3.1: [50][186] = 1, stored as 501861.0000

[0116] The corresponding algorithm can then be used for encoding and decoding processing.

[0117] The second is to appropriately reduce the wave packet sampling rate. Theoretically speaking, the higher the wave packet sampling rate, the higher the resolution, and the better the result of beat recognition. However, the experiment proves that the result of beat recognition remains unchanged when the sampling rate is reduced appropriately. This can double the speed of operation.

[0118] 3. Dance Strategy

[0119] After calculating the rhythm of the music, match it with the rhythm pattern in the rhythm-dance library to get the best matching solution and determine the dance movements that the robot will perform; then, according to the result of the beat prediction, decide when the robot ...

Abstract

The invention relates to an anthropomorphic robot autonomously dancing along with rhythm. The brain of the robot is provided with an embedded computer system with musical rhythm recognition capability. The embedded computer system mainly comprises a hearing subsystem, a rhythm recognition subsystem and a dancing movement combination subsystem; wherein, the hearing subsystem obtains external played music by a sensor and converts the music into digital music signals which serve as the input of the rhythm recognition subsystem; the rhythm recognition subsystem processes the digital music signals and obtains the rhythm of the music and the characters of beats which comprises beats per minute and the beginning time of beats; the dancing movement combination subsystem autonomously combines dances according to the rhythm characters obtained by the rhythm recognition subsystem; the three subsystems process in parallel in the mode of a production line to cause the robot to autonomously dance along with rhythm. The anthropomorphic robot can autonomously perform a complete set of graceful and integrated dances along with the rhythm of the music. In addition, the anthropomorphic robot has the application prospect of art, education and recreational activity.

Description

technical field [0001] The invention relates to a robot, in particular to a humanoid robot dancing with rhythm. Background technique [0002] As an interesting and complex field of artificial intelligence research, robotics integrates high-tech in many fields such as robotics, mechatronics, multi-agent collaboration, real-time vision system, wireless communication, and artificial intelligence. [0003] At present, the research of humanoid robots is mainly promoted by two major competitions in the world, namely FIRA and ROBOCUP. In these two competitions, humanoid robot dance competitions are added. Robot research at home and abroad is developing in depth, and the intelligence level of robots has always been the main issue that researchers focus on: on the one hand, they hope to improve the multidisciplinary cooperative research of robots through robot football games; on the other hand, robots are also moving towards a more comprehensive The development of intelligence and w...
