My cat-chasing robot

This is very early. The robot doesn’t yet have any sensors. It has two front wheels and a caster in the center back.

My plan is to put some thermal motion detectors on it and go towards the motion.

At the moment it just goes in squares. Forwards for a second and a half, then counter-rotate the wheels to make a rough 90-degree turn. Repeat.

Obviously, loose wires will need to be fastened, or cats will chew on them.

  1. BTW, my carpet isn’t really that color. That’s an artifact of the lighting and the camera. It’s actually Real Estate Beige.

  2. Oh, sure that’s what EVERYONE with bright golden yellow carpet says. :)

  3. Ohh how I love you. Let me count the ways! x] HAHAHAHA! I love it!

  4. I’m sure glad there’s someone in the world working on this very urgent project. How to herd cats is a problem that no one has ever discovered a solution for.
