Hasta La Gadget!

A while back we got a detailed look at the innards of Qbo, TheCorpora’s open-source robot. But we haven’t gotten to see the little guy in action — until now. His handlers recently let him loose to run autonomously, guided by a pair of webcam eyes and voice recognition courtesy of Willow Garage’s ROS software. The team soon noticed some unexpected behavior, though. Despite being programmed to follow humans at a specific distance, Qbo trailed uncomfortably near with taller people — probably the first example of a robotic “close walker.” Poring over the log files revealed why: proximity was calculated based on faces. The faces of taller people were farther away from the ground-hugging robot, which adjusted accordingly. Roll your way down the page to see more of our cute mechanized friend, and over to the source link for more musings on programming him.

Qi-Hardware has a bit of an obsession with free, open source, and underpowered. The latest project from this descendent of OpenMoko is a set of license free wireless boards called atben (for the company’s Ben NanoNote) and atusb for other laptops. The adapters rely on the IEEE 802.15.4 standard which powers 6LoWPAN and ZigBee. Don’t get confused though, this is not a replacement for WiFi — it’s more like long range Bluetooth (and it’s not compatible with either). Ben WPAN, as it’s being called, has a range of about ten meters in “standard” mode while pushing 250Kbps. Turning on the “non-standard” mode boosts throughput to (a still patience-testing) 2Mbps, but cuts the range in half. You can pick up pre-built adapters starting at €29.50 (about $42) for the atben, €41.30 ($59) for the atusb, or €59.00 ($84) for both at Tuxbrain. Don’t expect to just jam one into your Mac however — for now at least, Ben WPAN is a Linux only affair. (How often do you hear that?)

Ever since the Boxee Box was released fans running the software on their PCs have been left by the wayside, but as we expected that changes this fall with updates for the PC, Mac and Ubuntu versions. CEO Avner Ronen announced on the official blog that while updates for the downloadable version “will most likely lag behind the versions of Boxee for devices” the company hopes to keep them more up to speed going forward. Still think you could do a better job of updating the software yourself? Done, since Boxee also plans to make an open source version available. There’s no date attached to that effort and given past experience with delayed Boxee releases we wouldn’t clear our college football watching schedule just yet, but for everyone who would rather roll their own media device there is still a future in the Boxee platform.

It’s been nearly twenty years since Linus Torvalds let loose Linux on an unsuspecting world, and yesterday he finally updated the open source OS kernel to version 3.0. This third iteration, currently named 3.0.0-rc1, comes 15 years after 2.0 first hit the web and brings driver support for Microsoft Kinect — a move that should have visions of sugar plum fairies (or maybe just Android avatars) dancing in hackers’ heads. Also included is code optimized for AMD’s Fusion and Intel’s Ivy and Sandy Bridge silicon, and some updated graphics drivers, too. Despite these tasty new treats, Torvalds is quick to point out that this new release is an evolutionary change and unleashing the big three-oh was all about moving into a third decade of distribution, not about overhauling the OS. There’s still work to be done, as it is a release candidate in need of refinement, but curious coders can grab the latest Linux at the Kernel.org source link below.

LifeFitness may have taken one too many creative liberties with its Cyberbike Wii accessory, but it did a laudable job of redeeming itself at Google I/O this week. The outfit brought a USB-equipped exercise bike to the show floor, where an Open Accessory-enabled Nexus S promptly stole the show. We were shown a demo of the CardioQuest app interfacing with the cycle over the aforementioned protocol; the bike itself had a heretofore unreleased firmware update installed that allowed it to interact with the phone, and we’re told that said update will be available free of charge to existing customers in the coming weeks.

As was announced yesterday during the opening keynote, the Android Open Accessory API is currently only capable of handling communications over USB, but that didn’t stop a clever game from keeping a booth representative mighty busy. The gist is pretty simple — pedal harder to move the Android up, and relax your stride to see him float down. The goal is to avoid the surrounding walls, while also keeping your mind from focusing on the fact that you’re actually burning calories. Mum’s the word on whether or not this particular app will ever make it into the Android Market, but there’s a video of the chaos waiting just after the break, regardless.
