Developing software for safety-critical systems? This book is for you

In-depth volume covers development of systems under the IEC 61508, ISO 26262, EN 50128, and IEC 62304 standards

In June, I told you of an upcoming book by my colleague Chris Hobbs, who works as a software safety specialist here at QNX Software Systems. Well, I’m happy to say that the book is now available. It’s called Embedded Software Development for Safety-Critical Systems and it explores design practices for building medical devices, railway control systems, industrial control systems, and, of course, automotive ADAS devices.

The book:

• covers the development of safety-critical systems under ISO 26262, IEC 61508, EN 50128, and IEC 62304
• helps developers learn how to justify their work to external auditors
• discusses the advantages and disadvantages of architectural and design practices recommended in the standards, including replication and diversification, anomaly detection, and so-called “safety bag” systems
• examines the use of open-source components in safety-critical systems

Interested? I invite to you to visit the CRC Press website, where you can view the full Table of Contents and, of course, order the book.

Autonomous forklifts gear up with QNX and HTML5

Warehouse robots need reliable realtime control. They also need an intuitive user interface. Can one OS handle both?

When it comes to forklifts, I am as dumb as they come. I had always assumed that one forklift is much like any other, aside from obvious differences in size and color. Boy, did I get that wrong. A quick perusal of Wikipedia reveals some 30 forklift types, ranging from “walkie stackers” (which, true to their name, are walked, not ridden) to “EX-rated lift trucks” (which, contrary to their name, aren’t designed to carry erotica but to be explosion proof).

Forklifts also come in driverless variants called automated guided vehicles, or AGVs. Case in point: the QNX-powered AGVs built by Euroimpianti, a global leader in automated warehouse systems. These vehicles can, without human intervention, load and unload trucks, as well as move materials from one area of a warehouse or factory to another. Moreover, they can operate 24/7, using a list of prioritized missions downloaded from a central management system.

As you might expect, Euroimpianti uses the QNX Neutrino OS in the realtime control systems of its AGVs. After all, predictable response times and high reliability — qualities essential to safe operation of a driverless vehicle in a busy warehouse — are QNX Neutrino’s stock-in-trade.

But here’s the thing: Euroimpianti has also decided to standardize on QNX Neutrino for the human machine interfaces (HMIs) of its operator panels. Why do that, when the HMIs could run on an OS like Windows Embedded or Android? The answer lies in the many features introduced in the QNX Neutrino OS 6.6 and the new QNX SDK for Apps and Media.

These features include a framework for creating apps and HMIs with industry-standard technologies like HTML5, JavaScript, and CSS, and a graphical composition manager that can seamlessly blend apps and graphical components created in HTML5, OpenGL ES, Qt, and other environments, all on the same display. In addition, the SDK offers secure application management, comprehensive multimedia support, mobile device connectivity, an optimized HTML5 engine, and other features for building mobile-class user experiences into embedded systems — including, of course, AGVs.

To quote Maurizio Calgaro, electronic engineering manager, Euroimpianti, “With its new QNX SDK for Apps and Media, QNX Neutrino enables us to create dynamic HMIs that leverage the latest Web technologies, including HTML5. Our operator panels and control systems can now run on the same, standards-based OS, and that means greater productivity for our developers and, ultimately, faster time-to-market for our solutions.”

The QNX SDK for Apps and Media includes an HTML5 environment to create and deploy applications.

Euroimpianti's QNX-based robotic systems also include Cartesian robots, anthropomorphic robots, and selective compliance assembly robot arms (SCARA). The systems are deployed internationally in the automotive, beverage, cosmetic, food, dairy, electrical, glass, and pharmaceutical industries.

Using the same OS for both realtime control and user interface control.

I so need one of these!

You can work hard. You can work smart. Here's a robot vacuum that does both. It's called the Neato BotVac, and it uses laser technology to scan and map a room before cleaning it. Now, that's pretty cool.

Did I mention? It runs on the QNX OS.

Just the thing for your autonomous car

Don't know about you, but when I finally get a car that does all the driving for me, I'm going to become very lazy, very fast. Which means I'll be super unhappy every time my car needs a fill-up. Think about it: I will have to haul my butt out of the car and fill the tank myself. The horror!

But you know what? It turns out my fears are groundless. Because Husky Corporation and Fuelmatics AB have collaborated on a — you guessed it — automatic refueling system:



Kidding aside, this system could be of benefit long before autonomous vehicles become ubiquitous. According to Husky, it can cut 30% off the time it takes to refuel, so gas stations could sell more gas in the same amount of time, and with fewer lineups.

Also, this could be just the thing for any region where winter has the upper hand — virtually all of Canada, for instance. If you're ever stepped out of your car in -30 C temperatures to gas up, you know of which I speak.
