The core control of a haircutting robot lies in the motion planning and execution of its manipulator arm. As a mechanical system with high degrees of freedom, each hair-cutting action requires precise control algorithms to ensure smoothness and accuracy of movement. This section focuses on the algorithmic modeling of haircutting actions, covering inverse kinematics, neural network–based control strategies, and other intelligent control methods to ensure the robot’s flexibility and safety during the haircutting process.
