Difficult times even for guide dogs. A robotic concept of assistant to the walk of people with visual impairments uses GPS to travel through the cities with greater precision than our four-legged friend.
It's about the NSK robot, able to assist the handicapped in the path but not to console them when they are melancholy: I put aside the romance for a moment and continue to hope that all friends in difficulty can cuddle their dog once they return home, but to go down in road will be able to count on a support able to "remember" all the roads in the world.
