While more future work can be conducted in order to break through the limits of the current exoskeleton system, this provides 'the next step' for future exoskeleton systems. People - Biomechatronics Lab . . Lerner said of the group's future plans: Weve primarily focused on the ankle joint, and designing single-joint exoskeleton technology for individuals who have some ability to walk, but theres a lot of value in exploring and refining technology to different joints. The device is designed with dual functionality in mind; aside from aiding in walking, it is capable of providing resistive training to improve overall ankle strength and mobility. The webpage is built in anvil.works. Located in Flagstaff,ranked one of the best college towns to live inand among the happiest cities in America, Northern Arizona University is a growing institution classified as an R2 School (higher research activity).
