A powered Exoskeleton or Exosuit is a wearable mobile machine that is powered by a system of electric motors, pneumatics, hydraulics, or a combination of technologies that allow for limb movement with increased strength and endurance.This project focuses its efforts on the modeling, basic analysis, development (using CATIA) and testing of a pneumatically powered upper body Exoskeleton prototype which is cost-effective and meant specifically for assistive load-lifting.The possible applications are numerous and spread across various fields such as in MSME’s (Micro, small and medium scale industries, automobile industry, search and rescue operations, transport and logistics, medical industry, construction industry and many other small scale industries. The team has successfully built a wearable prototype and achieved a lifting capacity of 17kgs per arm. A 5/3 double solenoid valve has been uniquely utilized for intermediate motions of the arms. Further work to improve lifting capacity, mobility, flexibility, controlled synchronized lifting and optimization of the performance of the Exosuit prototype is being contemplated.
