If you have a cat, you know what it's like when they decide it's time to play. This DIY Cat Laser Robot , shared by Benjamin of the TrionFilms YouTube channel, was designed specifically to include your feline friend! It uses a Raspberry Pi to move a laser light around the room for your cat, or any other interested pet, to chase.

In addition to boasting the Pi single-board computer, this robot uses a couple of servo motors to move its laser. The original prototype was completely automated with pre-programmed movements.

Benjamin designed and 3D printed a case for the final build. The servo motors are controlled with the help of a Python library. In the final iteration, Benjamin opted to control the laser manually with the arrow keys on a keyboard .

Unfortunately, the Python library doesn't provide any tools for recognizing the release of a key press. As a workaround, you have to press Enter to stop the laser from moving. This makes controlling the robot a bit trickier but leaves room for future modifications.
