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 disabled people along the way but not to console them when they are melancholy: I put romanticism aside for a moment and continue to hope that all friends in difficulty will be able to cuddle their dog once they return home, but to take to the streets they will be able to count on a support capable of "remembering" all the roads of the world.
