Exoskeletons for gait rehabilitation and biomechanical analysis has advanced from conceptual designs to functional prototypes, yet most remain confined to laboratory research. This paper presents the process of scaling an exoskeleton prototype for gait analysis, focusing on three critical stages: prototype development, pilot testing, and clinical validation. A case study is presented involving a scaled dummy actuated by AX-12W servomotors and controlled with an Arduino Mega, programmed to follow gait signals derived from videogrammetry data of healthy individuals. The prototype demonstrates the feasibility of embedding human gait data into robotic control, highlighting its potential as a low-cost experimental platform for future rehabilitation research.
