About

Tzung-Liang Hour is a robotics researcher whose work has focused on one of the most fundamental and challenging problems in robotic manipulation: the analysis and resolution of singularities. His research addresses the critical issue that occurs when a robot arm approaches a singular configuration, where a degree of freedom is lost and the manipulator cannot move in certain directions. Hour’s most cited work, "Study and resolution of singularities for a 6-DOF PUMA manipulator" (1997), has garnered 81 citations and provides a systematic method for solving the inverse kinematics problem while accounting for these singular points. He extended this analysis to five-axis industrial robots in his 2002 paper on the GRYPHON manipulator, demonstrating the broader applicability of his approach. By developing practical resolution strategies, Hour’s contributions help ensure that robotic arms can operate smoothly and reliably near singular configurations—a vital consideration for precision manufacturing and automation. His work remains a key reference for engineers and researchers working on robot kinematics and control.
