RoboSentry: a robotic protection system
What happens when you combine a tripod, miscelaneous hardware, a continuous rotation servo, an "Uno Attack" game, two PIR sensors, one Ping sensor, and a relay board? You get the RoboSentry; a fully autonomous robot guard. two PIR sensors are used to detect motion and set off an audible alarm. A ping sensor mounted on a panning mechanisim is the sensor that triggers the firing mechanisim. The firing mechanisim is a modified "Uno Atack" game. The game consists of a Card launching mechanisim (instead of a "draw Pile") and two decks of uno cards. I Removed the old circuitry from the game, taped it onto a dinner plate, and then taped the Ping sensor onto the dinner plate to form the panning/firing mechanisim. This was mounted onto a continuous rotation servo (Standard servos don't give a smmoth, slow glide like CR servos do) and the servo was mounted onto a stingray chassis plate to form the baseplate. A Board Of Education and BS2 controlls the whole thing. A relay board is used to control the card launcher. I added an IR sensor as a way to arm or disarm the RoboSetry. The circuit is wired up as follows: the relay board is conected to pin 0, a status led is connected to p1, the IR sensor connects to p2, the Piezospeaker connects to p4, the two PIR sensors connect to p12 and p13, the Ping connects to p14, and the servo connects to p15. the entire device is screwed onto a (crummy) tripod. A video will be comming sooner (or later).

So if an intruder enters the room, they get a face full of Uno cards? That would be something to see.
Does it work at keeping siblings out of your room?
We need a video!
Thanks for posting.
