Evaluation of a vocational robot with a quadriplegic employee

A vocational robotic workstation capable of performing activities of daily living (ADL) and vocational tasks was placed for 18 months in the work site of an employee with C4 to C5 quadriplegia. A single-subject study was conducted to evaluate the performance of the robot vs that of a human attendant. The employee preferred the robot over the attendant for performance of all vocational tasks and ADLs, with the exception of feeding. Results indicated that the robot was capable of safely replacing the attendant for two five-hour periods during the workday, thus proving to be a cost-effective alternative to full-time, on-the-job attendant care. The study demonstrated the potential of robotics technology for returning independence and control to disabled employees and for offering corporate employers a solution to the problem of reasonable accommodation in the workplace.
