Title: Yizhang Lìu: Innovator in Robotics
Introduction
Yizhang Lìu is a prominent inventor based in Shenzhen, China. He has made significant contributions to the field of robotics, particularly in the areas of robot state estimation and stability control. With a total of 3 patents to his name, Lìu is recognized for his innovative approaches to enhancing robot functionality and stability.
Latest Patents
Lìu's latest patents include a robot state estimation method, a computer-readable storage medium, and a legged robot. The robot state estimation method involves obtaining force information from both the left and right legs of a robot. It calculates the Zero Moment Point (ZMP) in a world coordinate system based on this force information. Additionally, it determines the position of the center of mass (CoM) using a preset linear inverted pendulum model. This innovative approach constructs a new linear inverted pendulum model that considers the ZMP's influence on the CoM's position.
Another notable patent is the robot stability control method. This method includes obtaining a desired ZMP and a feedback actual ZMP at a given moment. By utilizing a ZMP tracking control model, Lìu calculates the desired motion state of the CoM, which includes a correction amount for its position. The method further employs a spring-mass-damping-acceleration model to derive a lead control input amount for the CoM's position correction, ensuring effective motion control of the robot.
