Maybe because the psychological benefits extend beyond accompanying the dog twice daily to the toilet? It is actually possible to spend time with the dog indoors as well. And having a dog-walking robot would enable people like me to actually get to experience some of those benefits. I won't even consider having a dog now, since it would be stuck inside the house alone for 9-10 hours a day, but if there were a robot to take it for walks and keep it company, it might be a possibility. (I figure that if toddlers see robots as peers, dogs will probably be ok with them too...)
