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
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!
