Smart exoskeleton suit is an intelligent wearable bionic power assist system integrated with AI gait recognition sensors, high-response servo actuators and self-adaptive control modules. This smart exoskeleton suit delivers dynamic graded power support to waist, hip and knee joints, automatically adjusting auxiliary torque according to walking speed, terrain slope and carrying weight to cut lower limb load during long-distance hiking, field inspection, warehouse cargo handling and lower limb rehabilitation training. It greatly relieves muscle strain and joint soreness caused by long-time standing and walking, effectively reducing physical fatigue. Built with ultra-light high-rigidity carbon fiber frame and IP54 dustproof, waterproof and scratch-resistant outer shell, the smart exoskeleton suit runs steadily in humid forests, rugged mountain roads and dusty construction environments. Full adjustable shoulder, waist and leg binding straps fit all heights and body shapes, paired with swappable large-capacity lithium batteries to realize all-day uninterrupted operation. Adopting ergonomic flexible joint design without movement restriction, this smart exoskeleton suit is widely suitable for logistics operators, outdoor explorers, field surveyors, seniors and mobility-impaired rehabilitation users, bringing smooth natural human-machine linkage and greatly improving working efficiency and outdoor mobility endurance.
