About

Dr. Qiang Qiang is a pioneering roboticist whose research focuses on the design, modeling, and control of nonholonomic mobile robots, with a particular emphasis on spherical robots for unstructured environments. His most significant contribution is the development of the BHQ series of spherical mobile robots, including the BHQ-1 and BHQ-2, which are driven by internal motors for stable, omnidirectional motion. Dr. Qiang’s work on trajectory tracking for spherical robots is especially notable; his 2008 paper, “A Back-stepping Based Trajectory Tracking Controller for a Non-chained Nonholonomic Spherical Robot” (21 citations), introduced a novel controller using the Boltzmann-Hamel equation and back-stepping method, enabling global asymptotic tracking of desired paths. This work addresses the critical challenge of robust control in hostile environments, enhancing the survivability and application of spherical robots for autonomous exploration. Beyond spherical robotics, Dr. Qiang has contributed to medical robotics, including a needle placement robot for liver cancer therapy, and to humanoid robotic finger development. His earlier work on robot inverse kinematics using fuzzy C-means and neural networks (2001) demonstrated a fast, effective method for solving complex kinematic problems. With a career spanning over two decades, Dr. Qiang’s research has laid foundational principles for non-chained nonholonomic systems and continues to inspire advancements in mobile robotics for real-world applications.
