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, capable of assisting disabled people on their journey but not consoling them when they are melancholy: I put romanticism aside for a moment and continue to hope that all friends in difficulty can cuddle their dog once they return home, but to get down to road will be able to count on a support capable of "remembering" all the roads in the world.
