About

Dr. Jianjun Qin is a mechanical engineer and robotics researcher whose work bridges reconfigurable mechanism design and decision-making in product development. His primary research areas include closed-chain robot kinematics, reconfigurable leg mechanisms, and systematic design evaluation. Dr. Qin’s most notable contribution is the design and analysis of a novel reconfigurable closed-chain robot leg, published in 2021. By introducing a composite hinge into the traditional closed-loop kinematic chain, his work overcomes the limitation of fixed foot trajectories, enabling greater adaptability in robotic locomotion. This innovation has garnered 3 citations and represents a significant step toward more versatile walking robots. In earlier work (2016), Dr. Qin addressed a critical challenge in conceptual design: how to objectively select the best scheme from multiple alternatives. By integrating Axiomatic Design Theory with Markov analysis, he developed a method that accounts for different designer preferences, providing a more rigorous framework for decision-making in new product development. With a focus on both theoretical rigor and practical application, Dr. Qin’s research offers valuable tools for engineers designing adaptive robotic systems and for teams navigating complex design choices.
