This instructable details the robot that I built for class at school. (For the robot contest I'll tell you that I'm between 13 and 18)
- 1 PICAXE programming board
- 2' of 7/64" metal dowel
- 1 1'x1' black plastic sheet
- 2 servo motors
- 1 9V battery
- hot glue
- 2 wheels (I used these wheels from Polulu)

Obviously, you can substitute most of these: plastic can easily be substituted for cardboard and the servos could be DC motors as well (although the robot wouldn't turn) -- etc.

A 3D CAD rendering of the pictured robot is available here!

Note: although the pictured robot includes gears, they are a little beyond the scope of this discussion and therefore are excluded from the guide.
Let's get started!

Step 1: Preparation

Cut dowels to length of robot (my chassis is 4" wide).

Cut two plastic sections: one 6"x3" and one 4" by 3". bend the 6" piece so that it's one 2"x3" and one 4"x3" piece (still stuck together).

Glue servo motors to the underside of the angle on the bent piece.
