Chuck McManis

Sensing Obstacles with Mobile Robots

Critical to mobility is knowing where you are. Chuck takes an in-depth look at three sensing technologies: switch bumpers, infrared light, and ultrasonics. He closes with a glimpse at radar and stereoscopic vision.


John Piccirillo

Designing Marvin

Building autonomous mobile robots is a challenging task. But, John succeeds with style. Listen up for the design and construction of Marvin, a winner in this year's Firefighting Home Robot Contest.


Ingo Cyliax

Modular Robot Controllers

Ingo describes some of the experiments for Stiquito II, a robot with Nitinol-wire-propelled legs. He looks specifically at the design strategies necessary for a controller system to be flexible enough for such robots.

In-Circuit Emulators

Part 2: Debuggers for Embedded Systems

After spending last month looking at software simulation and ROM emulation, the authors spend this month zeroing in on the more sophisticated monitor-based debuggers and true in-circuit emulators.


Ed Nisley

Firmware Furnace

Tuning Up: A Digital Zero-beat Meter

Hams communicate by tuning their radios to the same frequency. But, Ed has a lead ear. His new project listens to the transceiver's audio output and indicates which way to turn the knob for that Oh-So-Sweet same pitch.


Jeff Bachiochi

From the Bench

Nonintrusive Current Monitoring

This series begins with winding toroidal current sensors for monitoring power consumption in the home. Jeff designs front-end signal conditioning with an expandable multiplexer for use with the low-cost Domino microcomputer.


Tom Cantrell

Silicon Update

Spring Fling

With spring comes trade shows -- and lots of them! Through Tom, we get to walk through the Embedded Systems Conference East, Sensors Expo, and the PCI spring show. Come catch the highlights.

$500 Internet Browser in a Box

Who hasn't become entangled in the World Wide Web? It's growing and changing every day as more people gain access. This $500 set-top box is going to launch another segment of the population. A real spider's feast.

Part 2: The Application

Programming for WinLight or Windows requires development tools and techniques we may not be so familiar with. Here's a real-world clock application program and the tools needed to write, test, and debug it.

PC/104 Quarter

Precision Timing with PC/104

Real-time applications need accurate timekeeping. John shows how affordable precision time is available to portable and mobile systems based on PC/104. No more external synchronized clocks with bulky parallel interfaces.

Multiaxis Stepper Motors Continued

Fred walks us from his high-school slide-rule days into the modern world where milling machines use embedded intelligence coupled with motors and encoders. Take a turn at the wheel of this hands-on application.
