Clifford Donald Simak (August 3, 1904 – April 25, 1988)
One of the all-time great Science Fiction. Simak won three Hugo Awards and by colleagues with one Nebula Award and was nominated for many more. He was the third SFWA Grand Master and received a Bram Stoker Award for Lifetime Achievement. Several of his stories are freely available. Give some of them a chance (but not necessarily the X Minus One version of "Lulu" I love X Minus One, but they butcher this story, which isn't one of Simak's better ones)
• At Baen.com: "Lulu" Science Fiction from Galaxy. June 1957. [Via Free Speculative Fiction Online]
"Actually, there was no reason for us to go along with Lulu. As a matter of fact, it probably would have been a good deal better if we hadn't. She could have done the planet-checking without any supervision. But there were rules which said a robot of her class must be attended by no fewer than three humans."

"Old Buster, the troublesome mastodon, a lone bull which had been probably run out of a herd by a younger rival, stood at the edge of a grove a quarter-mile away. He had his head down and was curling and uncurling his trunk in an aimless sort of way while he teetered slowly in a lazy-crazy fashion by lifting first one foot and then another."

"The walk never varied. He paced two blocks down Maple Street, stopped at the Red Star confectionery to buy a Rose Trofero perfecto, then walked to the end of the fourth block on Maple. There he turned right on Lexington, followed Lexington to Oak, down Oak and so by way of Lincoln back to Maple again and to his home."
