Robot Instrument Motion Control for Rhythmic Head Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robots playing musical instruments, such as drum sets, exhibit simple actions, low personification, and insufficient dynamic characteristics, resulting in a poor performance effect due to their mechanized and specialized nature.
Innovation Solution
A motion control method for robots that involves obtaining a music file with multiple playing times and instruments, determining head positions based on the instruments, and controlling the robot's playing parts and head to execute actions that generate sounds and maintain corresponding positions, enhancing action diversity and personification by adapting to different orientations and trajectories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the robot executes periodic and repetitive actions, then the stability of actions is improved, but the richness and dynamic characteristics of actions deteriorate
Solution Approach 1:
The patent applies dynamics by enabling the robot to transition between different action modes (periodic repetitive actions and non-periodic expressive actions) based on musical requirements. The control system dynamically adjusts the robot's movements to match the rhythm, tempo, and emotional expression of the music, allowing the same robot to perform both stable repetitive tasks and rich varied expressions without mechanical specialization.
2Ease of operation
If the robot is designed for specialized functions, then the ease of operation for specific tasks is improved, but the adaptability to different musical instruments and performances deteriorates
Solution Approach 1:
The patent implements universality by designing a robot with multiple playing parts (hands, feet, etc.) that can be dynamically assigned to different musical instruments. The control system maps various instruments to appropriate playing parts based on their characteristics, allowing a single robot to perform on multiple instruments (drums, piano, guitar, etc.) without requiring specialized hardware for each instrument.
3Adaptability or versatility
If the robot performs complex playing actions, then the richness of performance is improved, but the device complexity increases
Solution Approach 1:
The patent applies self-service by implementing an automatic control system that autonomously determines playing trajectories, timing, and coordination of multiple playing parts based on music file analysis. The system automatically handles the complexity of coordinating hands, feet, and head movements to match musical rhythms and expressions, eliminating the need for complex manual control mechanisms while achieving rich performance.

AI summary
A motion control method applied to a robot and the robot are provided. The method includes: obtaining (S101) a music file to be performed, wherein the music file comprises a plurality of playing times and at least one played musical instrument at each playing time; determining (S102) a head position at each playing time according to the at least one played musical instrument at each playing time; and controlling (S103) a playing part and a head of the robot to execute a playing action, according to the at least one played musical instrument and the head position at each playing time, to allow a corresponding played musical instrument to generate a sound and allow the head to be in a corresponding head position at each playing time.
