A company called Tombot thinks it’s come up with a way to improve the quality of life for seniors facing challenges when it comes to being social: a robotic companion dog that behaves and responds like a real pup, but without all the responsibilities of maintaining a living, breathing animal. The company even enlisted the talented folks at the Jim Henson’s Creature Shop to help make the robo-dog look as lifelike as possible. It’s a noble effort, but it also raises lots of questions.
