Chapter 2 Getting the Parts 39

washers, and nylon spacers to assemble the PPRK. Not surprisingly, the best
place to get the frame and the hardware is Acroname. The Acroname frame
comes in three pieces and is already cut and drilled to the correct size; the
hardware is already selected to fit the holes drilled into the frame.

Miscellaneous Parts
This stuff is available at any hardware store:

❏ Double stick foam tape This is for attaching the battery holder
to the acrylic disk.

❏ 24 AWG wire You’ll use this stuff for connecting various
components. We recommend getting at least three different colors
for identification purposes.

Carry On
At some point, you will want to go beyond the servos and IR rangers that
come with the basic PPRK. Later in this book, in fact, we will do just that. You
can find a number of other sensors, including a flame detector, a compass, and
a line detector, all of which you can integrate into your Palm Robot.

A great web site for learning how to interface your PPRK to other sensors
and devices is Robert’s Gadgets and Gizmos: www.bpesolutions.com/gad-
gets.ws/gproject4.html.

A few of the alternate sensors mentioned at Robert’s Gadgets and Gizmos
include a light sensor, a temperature sensor, and a touch sensor. Both Robert’s
and the Acroname web sites also include information on how to interface
your robot with other output devices (as in Figure 2-9). In addition to operat-
ing the servos, for instance, the controller board from Acroname can be fitted
with a voice module. Robert’s Gadgets and Gizmos shows you how to use
the controller to turn light emitting diodes (LEDs) on and off. This barely
scratches the surface, of course, of what you can find at Robert’s Gadgets and
Gizmos, so be sure to spend some time exploring that site (see Figure 2-10).
