FIGURE 1. The ArdBot II,
ready to rumble.

Everyone wants a robot to serve them drinks and pick up their socks. Yet, despite how
mundane such tasks may sound, these chores require a sophisticated robot costing more than
the average automobile. The sensors and programming required to discern old socks from
sleeping cats requires extensive computing power, not to mention considerable skill on the
part of the programmer.
Your first robot doesn't have to be a mimic of C-3PO. It's better to start small, and grow
your robots as you gain experience. The ArdBot II is designed for simpler tasks, so it requires
only a small body, inexpensive sensors, and a $30 brain.
Last month, you learned how to construct the mechanical chassis of the ArdBot II.
This month, we'll move forward with completing its electrical subsystems, and giving the
robot its first taste of adventure by programming it with a simple servo test routine.
