Compact exoskeleton robot is a miniaturized wearable lower limb power assist device made of ultra-light high-rigidity composite materials, featuring an integrated compact frame design that greatly reduces overall volume for easy folding, storage and transportation. This compact exoskeleton robot is equipped with embedded AI gait recognition chips and micro terrain perception sensors, paired with low-noise miniature servo drive units to deliver adaptive dynamic auxiliary torque to hip and knee joints in real time. It automatically identifies flat ground, uphill and downhill road conditions, evenly disperses body weight and carrying loads to lower limb muscles, effectively relieving cumulative walking fatigue and long-term knee compression abrasion, while correcting abnormal gait for daily travel, clinical rehabilitation and short-distance mountain hiking. The streamlined compact structure avoids bulky redundant parts, supports fast wearing and removal, and reaches IP54 dustproof and splash-proof protection grade to adapt to indoor and outdoor complex environments. Fully adjustable ergonomic soft padded binding straps fit users of different heights and leg circumferences without local squeezing or friction discomfort. Matched with lightweight detachable lithium battery packs, it provides all-day continuous mobility support without bringing heavy extra burden. Bionic flexible joint structure completely retains the natural range of limb movement and will not restrict stepping, climbing and descending motions, with simplified one-touch intelligent control friendly to the elderly with insufficient leg strength, postoperative rehabilitation patients and field outdoor workers. Built-in anti-fall early warning, overload interlock and emergency stop triple safety modules effectively prevent slips and secondary injuries on uneven rugged ground. This multi-scenario compact exoskeleton robot achieves smooth human-machine motion synchronization, significantly improves long-distance walking comfort and extends continuous movement endurance while possessing outstanding compactness and portability.
