The energy-driven exoskeleton system analyzes the stress points and fragile parts of human body during lifting loads. It is designed to lessen load weight by using mechanical structure and power energy featuring active actuation at the waist and hips by energy power combined with passive assistance for the arms. This design provides targeted support to the waist-hip joints and arms when soldiers bend over to lift materials or carry them while walking so as to effectively reduce fatigue and injury risks while boosting operational efficiency.
