  • Your first robot: The controller [3/5]

    This is the third blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post you were introduced to the Robot Operating System (ROS), and got your robot moving by ROSifying one of the CamJam worksheets. Today we're going to move beyond the CamJam worksheets, and work toward having our robot remotely controlled by focusing on our wireless controller: getting data out of it and into ROS messages.

  • Tough, Atom-based box PC supports EtherCAT

    Taicenn’s Linux-ready “TBOX-4000” industrial box PC provides an Atom D2550, dual GbE ports with EtherCAT support, mSATA, optional wireless, and shock, vibration, and extended temperature resistance.

    Shenzhen based Taicenn Technology has launched a rugged industrial computer that runs Linux or Windows on an old school Intel Atom D2550 “Cedar Trail” processor with dual 1.86GHz cores, 640MHz Intel graphics, and a separate Intel NM10 controller chipset. The TBOX-4000’s D2550 chip has the advantage of being reasonably power efficient (10W TDP), leading to the computer’s under 20W total consumption. It’s also likely to make this computer more affordable than most, although no pricing was listed.

  • Developing an Open Source Voice Assistant: Interview with Mycroft AI’s Steve Penrod

    Mycroft is an industry first. Where Amazon Echo and Google Home are unsurprisingly closed-lipped about their data gathering, we know that recordings gathered from these devices are stored for later use (whatever that might be). Mycroft Mark II, by comparison, is an open source voice platform.

    This means that users of the Mycroft platform can opt into sharing their usage data and designers can then use that data to learn more about demographics, language, and voice recognition.

    On the other hand, users could choose to keep their data private.

    What we know about Mycroft Mark II's hardware is that it has a Xilinx quad-core processor, specifically a Zynq UltraScale+ EG MPSoC. It has an array of six far-field PDM-based MEMs microphones and has hardware acoustic echo cancellation (AEC) for beamforming and noise reduction. It has stereo sound with dual 2" drivers (10 Watts), a 4" IPS LCD touchscreen, BT 2.1+EDR and BLE 4.2 Bluetooth In, and single-band Wi-Fi (2.4 GHz).

Here Is What's New In Fedora 28

For those who don't know about this Linux distro, Fedora is one of those Linux distributions that comes released with cutting-edge software rather than staying on the same boat with other distributions that prefers stability. Fedora comes in three flavors: Workstation, Server, and Atomic. I'll be reviewing Fedora Workstation; used by many developers and users as their general purpose computing platform. Read
