This gorgeous robot patrols Steve’s yard, and honks its horn and squirts water when it spots an intruder. It features dual wishbone suspension, a 100-db car horn, and night vision, and runs off a Propeller microcontroller.

I set out to create an outdoor robot that would use all metal construction and include a suspension system. Being relegated to the great outdoors I also wanted to give it some harmless (but fun) defensive capabilities as well. In honor of it predecessor I’m naming this robot PatrolBot Mark II. And with its suspension and defensive systems I now have a robot that can smooth out the bumps and kick butt all at the same time.
