Embedded

At the JavaOne 2013 Java Technical Keynote, there was a series of demos of software that enables two people to play chess, using some of Java's latest features, including Java EE 7 Websockets, many variations of Java 8 (recent weekly builds), Lambda Expressions, Java ME, Embedded Java, ... It was an impressive demo of many of Java's recently-released and not-yet-finally-released capabilities,...

Some time ago, I had the impression that everywhere I stepped in the endless Java universe, I came across rather outdated technology. Things that were hyped years back, but for some reason had been left behind by mankind in the course of time. Disenchantedly roaming that programming desert I almost went depressive looking at all the rusty wrecks of former featured APIs laying around all along....

Java Desktop

Tuesday at Jfokus 2013 started in a large auditorium filled with more than 1500 Jfokus attendees, who heard Jfokus founder Mattias Karlsson launch the conference in an introduction that included an appearance by Stephen Chin, who had spent the previous night sailing the icy Baltic Ocean on the Vaadin Cruise from Finland. The conversation also introduced a new Java Champion, JRuby's Charles...

Robotics

 In May Google and Willow Garage announced the first pure-Java implementation of ROS - Willow Garage's Robotic Operating System. Called “rosjava”, the new library is still at alpha level, but it is clear from their forge that active development continues. Android is is well suited for robotic applications with its support of audio, accelerometers, GPS, cameras...

A few months ago James Gosling turned up at Liquid Robotics. Liquid Robotics designs robots called Wave Gliders that collect sensor data while wandering the seas. Rowboat sized, they raft along on the surface propelled by an underwater sled which translates vertical wave action into thrust. Solar powered, they are self-sufficient and able travel thousands of miles while transmitting data....

I just had the chance to play around with Bryan E. Smith's Lego Mindstorms robotics kit. We installed Lejos and I was coding programs directly from Netbeans. It was a lot of fun and surprisingly easy to use Java to control the robot. I've just added a Lego Minstorms kit to my wishlist, but I'm not sure that I'd spend $250 to buy a new kit versus another Nokia n810. We started with a standard NXT...

The huge projection screen at the front of the hall seemed to be a cut above what it's been in the past, in terms of brightness, color gamut, and resolution. When will I be able to turn the wall in front of my desk into a giant display? Sun Labs showed me a demo some months ago which mosaics several LCD projectors together to do just that. I'm ready... somehow staring at even a 20-something-inch...

This EETimes article implies that Sony is not capable of selling $2000 entertainment Aibo pets profitably. Sony will cut 10,000 jobs and pour more money into TVs and high-density DVDs. So much for what many view as a robotic success story: the Aibo US$2000 electronic pets. I don't own one, so it's not clear how this dog "keeps diary with pictures and is able to read e-mail or blog content", but...

This blog on ZDNET provides links to video and a press release from Global Composites and Distributed Robotics, both in NY state. Here's a PDF press release. If you want a smoother ride, here's a video of an elliptical wheel version. The inventor, Jason Winckler can be seen here with his frog Edna. This may be the same Jason Winclker who plays soccer for Tamarac Middle School. It's an interesting...

On behalf of Systronix and java.net, Bruce Boyes (that would be me) presented a proposal to standardize robotic I/O point tagging in a manner similar to the IEEE1451 STIM (Sensor-Transducer Interface Module). Systronix has developed a robotic tagging API, Java packages, and working examples. This package will soon be posted in the java.net robotics community. It will come as no surprise that...

We are looking for art that reflects the panorama of the possible interaction between 'synthetic' and organic life, e.g. - Autonomous agents that shape and perhaps interpret the data-saturated environment we have in common. - Portraits of inter-subjectivity or empathy shared between artificial entities and ourselves. - Intelligent anthropomorphisation of the datasphere and its inhabitants. -...

This InfoWorld article describes how an ASIC with an integrated transmitter is suspended in the middle of the ball to survive acceleration and hard kicks. Antennas in light masts and other locations distributed around the arena collect data that is transmitted from the ball. It uses the 2.4 GHz frequency range, and the developers are battling how to prevent interference with WiFi, among other...
