2013 RESEARCH YEARBOOK
Dr. Joseph Schimmels, P.E. professor, mechanical engineering Whatâ€™s he working on? Schimmels does research in robotics and prosthetics. His work focuses on the design of multidimensional mechanical behavior to achieve desired dynamic behavior during physical interaction. What are the new discoveries? In robotics, his research is directed toward improving robot dexterity. This work, in the short-term, is expected to lead to more reliable robotic assembly in manufacturing and, in the long-term, may lead to the level of dexterity needed to have robots function as human assistants. In prosthetics, Schimmels is working on a lower-leg prosthesis capable of providing user mobility close to that of a nonamputee. With support from a $600,000, three-year grant from the National Institute on Disability and Rehabilitation Research and other sources, he is developing a multi-directional mechanism that uses only conventional springs, cams and linkages to store and release energy at the appropriate time to propel the body forward during walking. This energy is obtained using only the personâ€™s weight and their normal body motion. This type of passive device can be produced at much less cost than one using active components, such as motors and batteries.
