Our wearable power assist system integrates advanced bionic exoskeleton framework and AI motion sensing module to deliver adaptive auxiliary power synchronously following human body movement. It effectively reduces lower limb energy loss during long-distance hiking, mountain climbing and outdoor field work, greatly alleviating compression on knees and waist to avoid fatigue from all-day outdoor activities. Built with IP54 dustproof and waterproof structure and wide temperature resistance, this wearable power assist system maintains stable performance under harsh conditions including low-temperature snowfields, high-temperature mountain areas and humid wild environments. The ergonomic overall design allows quick putting on and taking off, matched with interchangeable high-capacity batteries for long continuous working hours. Lightweight and portable, this wearable power assist system is perfectly suitable for outdoor explorers, field operators, expedition teams and people with inconvenient mobility, effectively breaking physical limits and making outdoor long-distance travel labor-saving and relaxing.
