Our full set of lower limb robotic systems consists of AI-driven wearable exoskeleton devices engineered with ultra-light aerospace composite materials, covering civilian mobility assistance, fitness training, elderly walking support and clinical gait rehabilitation for lower limb injury, stroke hemiplegia and degenerative muscle weakness. These integrated lower limb robotic systems adopt ergonomic bionic hip-knee linkage structures that fully fit human physiological movement curves without restricting walking, climbing, downhill and squatting motions. Equipped with multi-dimensional real-time gait and terrain sensing modules plus closed-loop adaptive servo control, the systems continuously capture joint angles and road gradient data, intelligently outputting graded dynamic auxiliary torque to evenly disperse body load and reduce strain on thigh muscles and knee joints. For rehabilitation scenarios, the systems simulate standard physiological walking trajectories to correct abnormal compensatory gaits and activate atrophied leg muscles; for outdoor and fitness use, they effectively delay physical fatigue and extend continuous movement duration. The foldable slim frame enables quick donning and compact storage, meeting IP54 dustproof, sweat and splash-proof standards to adapt to rehabilitation wards, family rooms and all-weather outdoor environments. Fully adjustable soft padded wrapping straps accommodate users of various heights and leg circumferences to avoid skin friction and compression discomfort during long-time wearing. Matched with swappable long-life lithium batteries and intuitive one-touch mode switching panels, operators can adjust assist intensity and training modes as needed. Built-in anti-fall balance aid, overload interlock and emergency stop safety modules lower risks of slips, sprains and secondary injuries during operation. These modular lower limb robotic systems support retail, bulk institutional procurement and OEM functional customization, delivering stable, safe and high-efficiency lower limb mobility solutions for global individual users, sports merchants and medical rehabilitation facilities.
