Smart gait robot is an AI-driven wearable lower limb exoskeleton equipped with high-precision real-time gait capture sensors and self-learning adaptive servo power system. This smart gait robot continuously collects stride, posture and terrain data during movement, intelligently analyzes individual gait features, and dynamically adjusts auxiliary power output for hip and knee joints to realize personalized assistance for flat walking, uphill climbing and downhill descending. It effectively corrects irregular gait patterns, reduces long-term pressure on lower limb muscles and joints, stabilizes body balance and restores natural bionic walking motions. The ultra-light high-strength composite frame meets IP54 dustproof and splash-proof standards, capable of stable use in home rehabilitation rooms, community walkways and gentle outdoor hiking paths. Widened soft padded adjustable straps accommodate users of different heights and leg circumferences, matched with replaceable long-lasting lithium battery packs to support all-day continuous gait training and walking assistance. Ergonomic flexible joints will not limit natural limb movement, with simplified one-button intelligent control that elderly users, hemiplegic rehabilitation patients and outdoor walkers can master quickly. Integrated anti-fall early warning, overload protection and emergency stop safety modules effectively avoid secondary injuries during long-time wearing. This all-scenario smart gait robot achieves high-precision human-machine synchronization, significantly improves gait correction efficiency and enhances long-distance walking comfort and mobility endurance for people with insufficient leg strength and mild movement disorders.
