MECHANICAL OPTIMIZATION DESIGN OF AN ACTIVE EXOSKELETON FOR THE KNEE DURING THE DAILY ASSISTANCE

This study presents the design and development of an improved knee exoskeleton system based on the work of Andrea Mauro. The innovation introduces a compact roller mechanism to enhance adaptability and adjustability of the exoskeleton structure. The proposed system is intended for rehabilitation and assistance in daily human movements, particularly for individuals with partial mobility loss due to neurological conditions. The exoskeleton is designed to provide support equal to 30% of the maximum knee joint torque required in daily activities. The prototype enables three primary movements: walking on level ground, ascending/descending stairs, and sitting/standing from a chair. The system was modeled and analyzed using SolidWorks, demonstrating its feasibility and effectiveness for rehabilitation and assistive purposes.
