INTRODUCTION
One of the key points to keep in mind while designing is,
what will you build your robot out of? For the beginning robot
builder this can be particularly vital. What materials are you
familiar with? Do you have the tools to work with a certain type
of material? How much does a material cost? How much will
the body weigh when complete? All these are questions that
you will have to ask yourself. You can answer most of these
questions if you use a body that is already built. Where can you
get a prebuilt robot body? At your local variety store they are
called trashcans! Before you shudder at the idea that your robot
be made out of a trashcan, let us examine the advantages.
The main advantage of using a trashcan is that it is a
ready-made container that can be built on. Take for an exam-
ple a small metal garbage can, like that in Fig. I-19. Being
metal (galvanized steel), it is very sturdy and has the added
benefit of looking “robotic.” Even though it is made of metal it
can be easily cut and drilled. (Care should be taken when

this can be a robot!
