Evaluation of a robotic workstation for the disabled.

Experience with potential users is vital at all stages of the design of equipment for the disabled, not least in the field of rehabilitation robotics. The development of a robotic workstation for the disabled has progressed, over a period of 6 years, from the use of a cheap educational arm, to a specially engineered robot arm and workstation. The design and specification has been refined through constant evaluation by disabled users. Trials at a spinal injuries unit have given approval to the design and appearance of the latest robot arm and workstation, and have led to modifications to the user interface and software. Further trials have taken place in a user's home to investigate in greater depth the usefulness of a robotic workstation in a practical situation. The results of these trials are presented. It is proposed to refine the design of the arm for low-volume production, easy maintenance in the field and improved appearance.
