About

Alan A. Barhorst is a mechanical engineer whose research spans the dynamics of complex mechanical systems, biomechanics, and robotics education. His foundational work on "Contact/Impact in Hybrid Parameter Multiple Body Mechanical Systems" (1995, 14 citations) addresses the challenging problem of modeling systems that transition between free and constrained motion, using impulse-momentum techniques to analyze impact response—a key contribution to multibody dynamics theory. In biomechanics, Barhorst led a novel cadaveric study using robots to investigate intercondylar notch impingement of the anterior cruciate ligament (2018, 7 citations), providing experimental evidence that notch geometry may predispose individuals to ACL injury. He has also advanced affordable robotics education through programs like GEAR, BEST, and FIRST Robotics in West Texas (2011, 5 citations), promoting cost-effective K-12 STEM outreach. More recently, his work on robust dynamic modeling and trajectory tracking for omnidirectional mobile robots (2022, 3 citations) demonstrates ongoing contributions to autonomous systems. Barhorst’s career uniquely bridges theoretical mechanics, translational biomechanics, and educational access, making him a versatile figure in applied mechanics and engineering outreach.
