About
Keqing Lu is a precision engineering researcher specializing in sensor design and metrology for spherical joints—critical components in parallel manipulators, industrial robots, and medical equipment. His work focuses on developing capacitive sensing technologies to measure micro-clearances and rotational angles in real time, directly improving motion accuracy and compensating for mechanical errors without costly hardware upgrades. Lu’s most cited paper, “An Improved Capacitive Sensor for Detecting the Micro-Clearance of Spherical Joints” (2019, 13 citations), establishes a foundation for high-precision clearance detection. He further advanced the field with a novel spherical differential capacitive sensor for micro-clearance measurement (2018, 7 citations) and a capacitive approach for rotational angle detection (2019, 10 citations). Beyond spherical joints, Lu contributed to kinematic parameter identification for articulated arm coordinate measuring machines (2018, 8 citations), enhancing accuracy through repeatability and scaling factors. His error analysis of spherical capacitive sensors (2020) underscores his commitment to measurement fidelity. With cumulative citations exceeding 40, Lu’s innovations in capacitive sensing and kinematic calibration are pivotal for next-generation robotics and precision manufacturing.
