| Abstract: | Destined for the visually impaired, Robotic Travel Aid (RoTA) acts as an intelligent cart, guiding people across the streets. The 60 kg, 1-m tall mobile robot is equipped with a computer vision system, stereo camera sensor and voice interface. When moving, it is aware of its environment: it recognizes landmarks such as zebra-crossing marks or traffic signals, stopping when the light is red, and 'sees' cars or other pedestrians. In case of trouble, the robots communicates wirelessly with a service center, allowing it to give extra information on the trajectory and adapt the navigational information system. Now, a wheelchair robot is developed as the successor of RoTA, not only for the visually impaired, but also the disabled. |
