About

Wei Lai is a robotics researcher whose work centers on the kinematics and control of robotic manipulators, with a particular emphasis on parallel mechanisms like the Delta robot. In his most cited work, "The Forward and Inverse Kinematics of a Delta Robot" (2020, 25 citations), Lai provides a clear and rigorous mathematical framework for solving the motion equations that govern this high-speed, three-arm parallel robot—a foundational contribution for engineers designing pick-and-place automation systems. His research also tackles the challenge of controlling robot manipulators under real-world constraints. In "Extended High-gain Observer Based Output Feedback Linearization of Robot Manipulator" (2020), Lai addresses the classic problem of model uncertainty when only joint position measurements are available. By integrating an extended high-gain observer with feedback linearization, he proposes a robust control strategy that compensates for parameter errors and external disturbances, enabling more reliable performance without full-state feedback. This work bridges theoretical control methods with practical implementation, making it valuable for researchers in nonlinear control and industrial robotics. With a growing citation record, Wei Lai is establishing himself as a thoughtful contributor to the field of robot kinematics and control.
