This soft wearable robot is a flexible fabric-based lower limb power assist exoskeleton, abandoning rigid heavy metal frames and adopting lightweight elastic composite soft materials to deliver unrestricted, skin-friendly wearing experience for daily walking, outdoor hiking, fitness training and mild lower limb rehabilitation. Designed with integrated soft bionic tension drive structure and ergonomic wrapping straps, it closely fits leg contours without bulky protruding parts, allowing full freedom of squatting, climbing, downhill and strenuous leg movements with zero motion restriction. Built-in miniature silent sensing modules and adaptive soft drive units, the soft wearable robot captures real-time gait and terrain data, automatically identifies flat paths, uphill slopes and downhill sections, and outputs gentle follow-up auxiliary tension to hips and knees to share body weight and backpack loads. It evenly disperses lower limb pressure, alleviates persistent muscle soreness and reduces chronic knee strain after long-hour activity, while naturally optimizing irregular walking posture without rigid mechanical constraints. Ultra-light foldable construction enables easy rolling storage in backpacks and handbags, boasting IP54 dustproof and sweat-resistant performance suitable for home, gym and all-weather outdoor scenarios. Fully adjustable breathable padded binding bands fit all heights and leg circumferences, avoiding friction redness and stuffiness during all-day wear. Matched with tiny detachable low-power lithium batteries, it provides stable continuous assistance without obvious weight burden on legs. Simple one-touch intelligent control supports switching between assist and training modes, ideal for seniors with leg weakness, amateur fitness lovers, outdoor travelers and mild rehabilitation patients. Integrated overload protection, balance reminder and emergency stop safety modules effectively prevent sprains and secondary injuries on uneven terrain. This multi-scenario soft wearable robot achieves ultra-smooth human-machine coordination, stands out with outstanding flexibility, portability and comfort, and supports retail, wholesale and customized size tuning for personal and commercial purchasing needs.
