About

Xuechan Chen is a robotics and mechanical engineering researcher specializing in parallel mechanisms, redundant manipulators, and rehabilitation robotics. Their work bridges advanced kinematic theory with practical therapeutic applications, addressing real-world challenges in human-robot interaction and assistive technology. Chen's most influential contribution, "Kinematics and Singularity Analysis of a 7-DOF Redundant Manipulator" (2021, 24 citations), introduced an innovative approach to analyzing complex manipulators with consecutive parallel axes, offering new tools for singularity avoidance critical to safe robotic operation. Building on this foundation, Chen has made significant strides in ankle rehabilitation robotics, developing novel parallel mechanisms — including 3-UPU and 3-PUU/R configurations — that more faithfully replicate the physiological motion of the human ankle joint, a challenge that most existing rehabilitation robots fail to adequately address. These contributions have collectively garnered over 40 citations, reflecting their growing influence in the field. Chen's research on spherical parallel mechanisms (SPMs) further demonstrates a commitment to expanding the structural diversity and analytical depth of these systems, with applications spanning surgical robots and exoskeleton technologies. Overall, Chen's body of work represents a meaningful fusion of theoretical rigor and clinical relevance, making it valuable reading for engineers and researchers working at the intersection of robotics, biomechanics, and medical device design.
