Cardbot

This is my first robot and also my first electronic project, thank you the folks at LMR for a site that is so easy to learn from.

Cardbot

There is nothing very special about this robot he just navigates around without crashing into things (most of the time). His body is a fairly stiff cardboard cut into the shape of a regular octagon, the wheels are made of plastic jar covers with rubber bands to improve traction, each wheel is connected to the servo horn with screws, connections are made with jumper wires and a breadboard, the speaker was salvaged from an old electronic alarm clock and is connected in series with a 220 ohm resistor to reduce the current to a level that can be handled by the pin on the Arduino clone. Cardboard was used to make little boxes to hold the Arduino clone, and both the 9V and the 4 AA batteries. A bracket to hold the ultrasonic range finder was cut from a piece of a plastic ice cream container. It is all held together by double sided foam tape (thanks Chicken Parmi).
