(THIS IS A SCALED DOWN MODEL) This design is a solution that eliminates the cats' trouble of cleaning up sand. After the cat leaves the machine, thanks to the stepper motor it starts to spin slowly. Sand in the floor, starts to get into the holes. Since stool cannot pass through the hole, it remains at the base. With the help of the servo motor, the lid is opened and the feces are transferred to the box below. Step motor after cover is closed by servo motor it activates and the sphere slowly returns to its original state. As it rotates, the sand in it spreads to the bottom again and the sand is ready to be used again without damage. #gift
