> Today, Unitree unveiled their latest quadruped robot, the Unitree Go2. This robot comes packed with advanced features, including a 4D LIDAR sensor, a depth camera, and Wi-Fi6 connectivity. Additionally, the Unitree Go2 features an increased payload capacity in comparison to its predecessor.
> [Jeff Geerling] has tried building his own network-attached storage before, but found that the Raspberry Pi just wasn’t able to keep pace with his demands. He’s back with a new all-flash NAS build, and put his new design to the test against proper store-bought gear.
> Today we’re going to be using the new Arduino Uno R4 WiFi to build a controller for a PET bottle recycler. I’m doing this as the first part of a project, working towards building my own version of a PET bottle recycler to produce filament for my 3D printer.
> Robotic arms can be expensive especially if you want one with AI Vision support, but Yahboom DOFBOT robotic arm designed for NVIDIA Jetson Nano offers a lower cost alternative as the 6 DoF robot arm sells for about $289 with a VGA camera, or $481 with the Jetson Nano SBC included. We previously published a review of the myCobot 280 Pi robotic arm from Elephant Robotics, and while it’s working well, supports computer vision through the Raspberry Pi, and is nicely packaged, it sells for around $800 and up depending on the accessories, and one reader complained the “price tag is still way too high for exploration“.
> Mohammad Reza Sharifi has made a wireless Raspberry Pi Pico surveillance robot that uses a custom GUI made with LabVIEW.
> After news recently from ServeTheHome that Intel planned to stop doing their Intel NUC systems directly, they've now announced they've agreed to let ASUS carry it on.
> Dr. J Metz is Chair of the Ultra Ethernet Consortium and stated that there is no need to overhaul Ethernet, but instead, the team hopes to make adjustments over time that will improve efficiency.
> So far, a few specific technical hurdles have been identified, which the consortium intends to focus upon. This involves the development of APIs and specifications for various Ethernet communication protocols, interfaces and data structures to suit the needs of high-performance technology better.
> He managed to couple the original Leica range finders with the Raspberry Pi Zero and HQ Camera, so users get the feel of manually adjusting the focus. He couldn’t save the High Quality Camera’s anti-aliasing filter, however, as it kept getting caught on the new shutter, so the MPi only photographs in monochrome and natural light. It is still possible to correct photos taken under harsh street lighting with white balance.
