Hiking assistance robot is a terrain-adaptive wearable lower limb power exoskeleton designed for long-distance hiking, mountain trail trekking, forest patrol and loaded hillside travel. Equipped with high-precision gradient sensing modules and low-consumption high-torque adaptive servo system, this hiking assistance robot real-time detects terrain changes of flat roads, uphill slopes and downhill sections, and delivers dynamic targeted auxiliary torque to hip and knee joints to counteract body weight and backpack load. It effectively alleviates persistent muscle strain of thighs and calves, reduces long-term compression abrasion on knee joints and delays severe fatigue during all-day outdoor trekking, while maintaining stable and natural bionic gait on uneven mountain roads. The ultra-light high-rigidity composite frame adopts IP54 dustproof, splash-proof and anti-scratch shell, which can block mud splashes, light rain and gravel friction to adapt to complex wild mountain environments. Fully adjustable thick soft padded wrapping straps fit users of all heights and leg circumferences, matched with swappable large-capacity lithium battery packs to support long-hour non-stop hiking power support. Ergonomic flexible joint structure completely retains natural stepping, climbing and descending movement range, equipped with simple one-touch intelligent control, easy for hiking enthusiasts, forest rangers and mountain survey staff to operate without professional training. Built-in overload protection and anti-slip balance stabilization safety modules effectively prevent slipping and secondary injuries on rugged terrain. This durable hiking assistance robot realizes seamless human-machine motion synchronization, greatly relieves hiking exhaustion and extends continuous outdoor movement endurance for outdoor lovers and mountain field workers.
