Robot dogs become “man’s best friend” of people with Alzheimer’s and other types of dementia. Tom Stevens, a businessman, gave a robotic Labrador puppy to the people at a nursing home in Thousand Oaks, California. Stevens worked with the late muppets creator to make the robot move like a real dog. Stevens thinks that if the robot dog moves like a real dog, it will help to heal the people with dementia. “It didn’t just have to look real and feel real but it had to behave realistically as well,” Stevens said. The robot dog has 16 machines that control its actions, and it can respond to instructions. It can also identify the soft and hard human touches. He thought of making the robot dog when his mother got Alzheimer’s in 2011. He wished that technology would give closeness to people. Stevens will sell its first robot dogs in 2020.
