Check out this spooky robot pet.It is guaranteed to scare you.


 The company created a headless pet robot (basically a pillow with a tail) that they call a “therapeutic robot in the form of a cushion” to bring joy and healing to those who can’t have an animal of their own. Like a loving pet, the Fraken-pillow responds to your touch, wagging its lone when you scratch it in just the right spot. The cat pillow runs on rechargeable batteries, and it will go for about 8 hours between charges. It weighs 1,000 grams, which is just over 2 lbs. The pillow comes in two colors, Husky Gray and French Brown.

This robotic pillow wags and curls the tail on its own, via accelerometer in the pillow. Remember the concept of Accelerometer in the Expert Level? You might have known about X, Y, Z axis, right? Likewise, it does, refer to the picture below.

 
 
While it was originally crafted to provide comfort to seniors who aren't able to keep their pets anymore, this would also be a fun toy for a current cat owner to make their existing pets incredibly jealous.
After finishing the Expert Level, try to implement the accelerometer to make your own Headless Robotic Pillow!!
