Electronic compassing
is one of the most intelligent ways to provide
absolute heading information for a mobile
robot. In this article, Joseph explains why
the PNI V2Xe compass turned out to be the
best fit for his Mini Rover 7 robot, which
he modeled after the NASA/JPL Rocky 7 Mars
rover. p. 14

by Brian Millier
Now
that you’re familiar with ZeitControl’s BasicCard,
it’s time to take a closer look at the process
of programming one and incorporating it in
a design. Brian shows you how he integrated
BasicCard technology in the design of a liquid
nitrogen generator. p. 24

Build
a Small Robotics Platform
Ingo
Cyliax
Inspired by the robots used by public
works departments to investigate pipe damage in
local sewage systems, Ingo set out to build his
own robotic surveillance unit. Although small, this
RCM3610-based robot boasts bump sensors and an odometer.
Whether you need an inexpensive surveillance solution
or an upgradeable base module, this robotics platform
is the first step in the right direction. p.

Intelligent Sensors Network
Victor Kremin
Flash
Innovation 2003 First Prize Winner
Victor’s 68HC908QY4-based intelligent sensors network
is an inexpensive solution for applications that
require low-speed, two-wire bidirectional data communication.
A simple time-triggered protocol ensures a predictable
data delivery time. The quasi-harmonic constant
frequency network signals are sheltered from electromagnetic
compatibility problems. p. 38

Use a Microcontroller to Emulate an I2C
EEPROM
Jay Francis
It’s amazing what you can do with a PIC and a toy
robot. Jay presents an interesting project. He came
up with a method of interfacing to the electronics
of a Spybot robot by using a PIC16F876 to emulate
an I2C
EEPROM. The result is an enhanced robotics system
that’s the perfect foundation for more complex designs.

A Wireless Ethernet Solution for the People
Fred
Eady
Finding the right wireless solutions for your embedded
projects can be difficult, especially if you’re
on a tight budget and can’t get the right parts
and documentation. That’s why Fred set out to find
an accessible solution for those of you searching
for a sure-fire way to bring wireless Ethernet capability
to your designs. DPAC’s wireless 802.11b evaluation
and development kit turned out to be the perfect
fit. p. 58

“High voltage, high current, and flying objects.”
Need Ed write more? Nope. He’s already got your
attention. Read on to learn how Ed built his Lenz
Launcher, which can, as he so gently puts it, “punch
conductive disks into the ceiling with a loud bang
and bright sparks.” p. 64

How much do you really know about USB? This column
is a great place to start educating yourself about
the basics. And it couldn’t have come at a better
time. Serial and parallel ports may soon be things
of the past. p. 68

Tom Cantrell
If you’re thinking about designing a device that
plugs into Ethernet, Tom suggests that you learn
as much as possible about 802.3af. This column is
your power-over-Ethernet (PoE) primer. Read on to
see why Tom is so optimistic about PoE technology
and the chips that will drive it. p. 76
