My project in the Fire Extinguishing competition. Contains code, diagram of the connections and power supply and some images of the robot.
The arduino controlled mobile robot will run through a determined course, by following the wall to it's right, using an ultrassonic sensor. The objective is to find a lit candle and extinguish it's flame.
In the next image you can an image of the mobile robot.
And in the next image you can see a diagram of the connections and power supply of the robot.
