Walking assistance robot is a wearable lightweight lower limb exoskeleton robot designed for daily walking, uphill travel, outdoor short-distance hiking and lower limb rehabilitation training. Integrated with high-precision real-time gait sensors and quiet servo drive modules, this walking assistance robot can instantly identify standing, flat walking and climbing postures, output soft graded auxiliary torque to hips and knees, evenly disperse lower limb load and relieve joint soreness and muscle fatigue caused by long-time movement. The ultra-light high-rigidity composite frame adopts IP54 dustproof and waterproof design, which can operate stably in home environments, community roads and gentle mountain trails. Multi-layer soft adjustable binding belts fit users of different heights and leg circumferences, matched with replaceable long-life lithium batteries to support all-day continuous walking assistance. The flexible ergonomic joint structure will not restrict natural limb movement, with simple one-key control for easy operation. This walking assistance robot is widely suitable for the elderly with weak legs, postoperative rehabilitation patients, outdoor walkers and field staff, bringing smooth and safe human-machine coordination, greatly improving long-distance walking comfort and mobility endurance.
