As with any new technology, robotics is for now very a very practical science; its only purpose to serve and assist humanity. Robots currently perform dozens of useful functions in our society, such as building cars, vacuuming floors and dancing.
But as a technology matures and eventually fills all the useful niches, it tends to start producing products that no one needs nor asked for (the Snuggie, Slap Chop and Tater Mitts).
Enter the Poutbot™ 3000. Its sole purpose is to get its feelings hurt and then stalk off to its room where it will slam the door shut and sulk for a couple of hours. No amount of pleading or offerings of cookies and milk will get it to open the door; after a randomly generated time period it will get over its pout and silently emerge from its room, ready to start the cycle anew.
The Deluxe model will even tell its owners that it hates them and didn't ask to be born.

Here's the sketch for the Poutbot™ 300. As you can see the sketch was pretty rough, so I cleaned up the lines and made them look more machine-like.
