AbstractThe continuing evolution of orthopaedic solutions to common foot and ankle problems means engineers and clinicians need increasingly complex and physiologically correct models of human movement. The design uses new parts and improved methods designed to interface with current machines and operating procedures that simulate the movement of human walking. The team added three additional tendons to the foot-ankle model and replaced the current tendon actuators with more robust models, capable of larger forces and faster movement. These additional tendons resulted in the design, validation and implementation of additional actuators, load cells and accompanying electronics. Adding these components required designing a spacing flange to maintain physiologically accurate tendon pull direction while providing the necessary space for the movement systems. The team overhauled the electrical system so it could provide necessary power to all components. The sponsor can use these new additions to the robotic gait simulator to better model orthopaedic solutions to gait defects, such as poor posture and injury.
