Walkbot_K is an another independent model of Walkbot series that is dedicated to children. In case of children patient, stiffness and resistance are harder than adult and in the most case, they even have no experience of walking after birth. So treatment efficacy is much lower in spite of longer training time. To expect better outcomes, Walkbot_K was developed with the ankle drive motor in order to give gait balance and correct pattern. Also it provides relevant clinical information related to locomotion, including data on stiffness associated with spasticity or joint contracture, spatiotemporal data, hip, knee and ankle kinematic and kinetic force data during locomotion training. In addition, the playground design as per children’s eye level minimizes the difficulties and unfamiliarity of when children first confronted the equipment. Also, an age-appropriate augmented reality program is integrated into the system to maximize interactive participation and motivation to children.
