Dr. Robert (Bob) Hocken, Professor Emeritus of UNC Charlotte’s Mechanical Engineering and Engineering Science Department died on June 2, 2021. Dr. Hocken was an international leader in the field of precision engineering, an award-winning educator, and a much-loved professor and colleague.
One of the founding fathers of engineering and scientific research at UNC Charlotte, Dr. Hocken came to Charlotte in 1988 as the Norvin Kennedy Dickerson Jr. Distinguished Professor of Precision Engineering. He established and led the University’s Center for Precision Metrology until his retirement in May, 2014.
As a researcher, Dr. Hocken is known for transforming metrology in the U.S. and the world. A few of his significant research contributions include the invention of the original tracking interferometer system, commonly known today as a laser tracker, and pioneering work the field of software error correction for coordinate measuring machines and machine tools.
Dr. Hocken’s areas of research expertise included engineering metrology, nanotechnology, electro-optical instrumentation, atomic force microscopy and optical stethoscopy, and dimensional metrology for Computer Aided Manufacturing concentrating on advanced probes, controllers, surface measurement systems. He was the principal investigator for more than $14 million in externally funded projects, and authored more than 80 publications including journal reports, featured articles, and proceedings including invited lectures and presentations.
As a teacher, Dr. Hocken is remembered by his students as an inspiring mentor, who positively impacted the lives and careers of the thousands of undergraduate and graduate students who passed through his classroom. He understood and exemplified the importance of training students to be independent, critical and analytical engineers, with the professional skills needed in the modern world. He supervised more than 33 Ph.D. and master’s student theses, and won numerous teaching awards.
One of Dr. Hocken’s favorite tasks was acting as advisor for Mini-Baja team, which he did for 15 years. The Mini-Baja is a car, completely designed and built by students, that has to run over hills and trails, through mud and across water. The UNC Charlotte team always had an advantage with Dr. Hocken as its advisor, because not only was he an expert in mechanical design, but he also let the team practice in the fields and roads at his farm.
