TN students make autonomous wheelchair with robotic OS  
Students from the Amrita Vishwa Vidyapeetham, Tamil Nadu have developed a low-cost self-driving wheelchair that works on Robotic Operating System (ROS). Called 'Self-E', the wheelchair features sensors to create a map of the surroundings, along with obstacles which are displayed through an app. Users can touch any point on the map and the wheelchair will drive to that place automatically.
