About

Levi H. Armstrong is a leading researcher in the field of robotics, with a primary focus on the modeling, control, and compensation of transmission system errors in robotic manipulators. His most-cited work, "Modeling and Compensation of Backlash and Harmonic Drive-Induced Errors in Robotic Manipulators" (2014, 11 citations), addresses a critical challenge in precision robotics: the periodic, joint-dependent position errors caused by harmonic drives and the accuracy-limiting effects of backlash from wear or assembly issues. Armstrong’s major contribution lies in developing sophisticated models that capture these complex nonlinearities, enabling effective compensation strategies that significantly enhance manipulator repeatability and accuracy. This work is foundational for applications requiring high precision, such as surgical robotics and advanced manufacturing. While his citation count reflects a focused, emerging impact, his research is highly regarded for its practical relevance to real-world robotic systems, bridging the gap between theoretical modeling and industrial implementation. Armstrong continues to advance the reliability and performance of robotic hardware, making him a key figure in the evolution of next-generation automation.
