This wearable robotic exoskeleton is an AI intelligent lower limb power assist device made of ultra-light aerospace composite materials, integrating bionic mechanical structure, real-time gait sensing and adaptive servo drive technology to serve outdoor hiking, mountain trekking, fitness training, elderly walking assistance and postoperative gait rehabilitation. Designed with human-centered ergonomic wrapping frame and flexible hip-knee bionic joints, the wearable robotic exoskeleton perfectly fits the natural bending track of human legs without restricting walking, climbing, downhill and squatting movements. It can automatically identify flat ground, uphill slopes and rugged terrain, output dynamic adjustable auxiliary torque to share body weight and backpack loads, evenly disperse lower limb pressure, relieve cumulative muscle fatigue and long-term knee joint wear, and effectively extend continuous movement endurance. The streamlined foldable body realizes quick donning and compact storage in backpacks and car trunks, reaching IP54 dustproof, sweat and splash-proof protection standard for indoor rehabilitation rooms and all-weather outdoor environments. Fully adjustable soft elastic padding straps adapt to users of all heights and leg circumferences, avoiding skin friction and oppressive discomfort during long-time wearing. Equipped with lightweight detachable lithium batteries and one-touch multi-mode intelligent control, it switches freely between hiking, fitness and rehabilitation modes, easy to operate for the elderly with weak legs, rehabilitation patients, outdoor enthusiasts and field workers. Built-in anti-fall early warning, overload interlock and emergency stop triple safety modules prevent slips, sprains and secondary injuries on uneven ground. This multi-scenario wearable robotic exoskeleton achieves seamless human-machine motion synchronization, balances lightweight portability, stable power assist and complete safety protection, and supports retail, wholesale and OEM customization to meet personal, commercial and medical purchasing demands.
