About

Chengyu Wei is a researcher specializing in robotics, with a particular focus on the dynamic parameter identification of modular and industrial robot manipulators. His work addresses critical challenges in robot modeling and control, especially the nonlinear friction forces that hinder precise drag teaching and motion accuracy. Wei’s major contributions include the development of hybrid optimization strategies that combine genetic algorithms with least squares methods for robust parameter identification. His 2024 paper on this hybrid approach, which has already garnered 10 citations, demonstrates a significant advancement in the field. Additionally, his 2022 study on Stribeck friction model identification using genetic algorithms (6 citations) proposes a step-by-step method to accurately describe system friction, directly improving robot teachability. Wei also tackled the limitations of traditional genetic algorithms in meeting excitation trajectory constraints, introducing an improved genetic algorithm for six-axis industrial robots. With a growing citation impact, Wei’s work is foundational for researchers and engineers aiming to enhance robot precision, control, and human-robot interaction through more accurate dynamic modeling.
