Designed for smooth robot legs walking experience, this bionic lower limb assist equipment adopts multi-axis linkage drive and high-precision gait sensing modules to synchronize power output with every walking step naturally. When flat walking, uphill climbing and long-distance trekking, the robot legs walking system automatically distributes moderate auxiliary torque to hips and knees, reducing leg muscle consumption and easing continuous soreness of knee joints after long-time walking. Built with lightweight high-strength composite material and IP54 dustproof and waterproof sealing, it maintains stable walking assistance in mountain trails, damp wilderness and dusty working sites. The multi-way adjustable binding structure fits different leg circumferences and heights, matched with swappable large-capacity lithium batteries to support all-day continuous robot legs walking without frequent charging. Perfect for outdoor hikers, field staff, the elderly and people with weak lower limbs, this intelligent assist device delivers natural, unobstructed robot legs walking state and effectively extends outdoor travel endurance.
