Chapter 12Build a Motorized Metal Platform
Metal offers strength and ruggedness that wood and plastic cannot. While constructing robots out of metal requires more effort (and sharper tools for cutting and drilling), a properly made metallic bot will last years and years and is suitable for both indoor and outdoor use.
This chapter details the construction of a small but flexible TinBot, using metal for its principal body parts. Its design uses commonly found hardware, which keeps down its cost and limits the amount of hacking pieces of metal down to the size and shape you want. In fact, construction of the TinBot requires only two cuts through thin-gauge steel. The cuts are relatively easy to make using an ordinary hacksaw.
