Human-Machine Interfaces for a Lower Limb Rehabilitation Robotic System

This paper focuses on the research activities undertaken for the design and development of an advanced Human-Machine Interface (HMI) intended for the control of a lower limb rehabilitation robotic system. The presented process includes hardware and software development, from the initial concept to a fully functional experimental model. The HMI, created on a dedicated unit, is designed to be intuitive and user-friendly, allowing therapists to control the robotic system efficiently and comfortably. Using a user-centered design approach, the interface incorporates therapist feedback to meet specific rehabilitation needs. The robotic system is flexible and adapts to the unique requirements of each patient, supported by continuous information exchange between the patient, therapist, and system. The paper also covers the use of the TrioMotion Flex-6-Nano control unit and Uniplay 7-A HMI hardware, demonstrating how these technologies help create sophisticated while still easy-to-use interfaces for controlling robotic systems in rehabilitation.
