Designed and prototyped an electromechanical rehabilitation device to automate repetitive lower-body therapeutic exercises, reducing physical workload for physical therapists while maintaining controlled, repeatable patient motion.

Developed the mechanical system architecture in SolidWorks and evaluated kinematics, loading, and motion feasibility using MATLAB and MSC Adams. Simulation results informed actuator placement, load paths, and structural sizing prior to fabrication.

Built and tested a scaled physical prototype using over $7,000 in custom and off-the-shelf components, translating simulation assumptions into real-world constraints including manufacturability, alignment, and assembly tolerance.

Applied a statistics-based design approach to accommodate variation in body size and loading conditions, emphasizing robustness and mechanical feasibility across varied users.
