Figure 1From: A robotic wheelchair trainer: design overview and a feasibility studyROLY -RObot-assisted Learning for Young drivers. We developed a robotic wheelchair trainer that steers itself along a course marked by a line on the floor using computer vision, haptically guiding the child's hand in appropriate steering motions using a force feedback joystick. The child is instructed to follow the line with a spot of light from a laser pointer mounted on the chair, creating the smallest amount of error possible. To motivate the children during training, we programmed a small mobile robot to follow the same black line, and requested the child to try to catch it in a game of "robot tag".Back to article page
