Teaching Robot Helps Children to Use Wheelchair
A robotic wheelchair is being developed that will help children learn to 'drive'. Researchers describe the testing of ROLY –RObot-assisted Learning for Young drivers – in a group of children without disabilities and one child with cerebral palsy.
Laura Marchal-Crespo, worked with a team of researchers at the University of California at Irvine, USA, to carry out the study. "The conventional approach for powered wheelchair driver's training is expensive and labor-intense, typically requiring the hand-over-hand assistance of a skilled therapist”, she said. “To lower the cost and improve accessibility to training, we have developed a robotic powered wheelchair system on which young children with a disability can safely develop driving skills at their own pace with minimum assistance".
The researcher's technique involves the trainee learning to chase a small robot along a line painted on the floor. The force feedback joystick used to steer the wheelchair can also give physical assistance to the driver, at a level appropriate to their ongoing performance. When caught, the robot performs a dance and the chair plays a little tune.
The joystick haptic assistance was found to enhance learning in both the non-disabled children trained with haptic guidance and in the child with a severe motor impairment. Speaking about the results, Marchal-Crespo said, "Ultimately, we envision creating a training experience that compares favorably with the fun children experience with the best amusement park rides, but that facilitates the development of driving skill".
