myCobot 280 Pi is a versatile robotic arm with a 6 degree of freedom design. It was developed by Elephant Robotics using the Raspberry Pi 4 board as the main controller. The robot is compact and delivers stable operation making it ideal for confined spaces. It can also be programmed in a variety of languages, is easy to use, and offers a lot of features. It is suitable for those who are interested in learning how to program a robotic arm controller and for engineering projects. Unboxing myCobot 280 Pi The myCobot 280 Pi arm has a working range of 280 mm, weighs 850 grams, and can handle a payload of up to 250 grams. It is powered by 6 servo motors, one for each degree of freedom, and comes with a 5×5 matrix LED display, and supports LEGO parts as well. Controlled by a Raspberry Pi 4 single board [...] The post Review of myCobot 280 Pi robotic arm with Python and visual programming appeared first on CNX Software - Embedded Systems News.

Description kASLR is a handy security feature, with no performance downside. (The only downside is some slight inconvenience if you're using KGDB, but if you're the type of person who does kernel step debugging, it seems sane to guess you're already building your own kernel.) If it cannot be enabled due to lack of seed, the kernel will simply print a warning and continue. (See #4306 for more context on what was previously added to get it working on a NanoPi R4S.) I also believe this warning will be useful note for us to add rng support on all devices as time goes on. Example of failure: [ 0.052888] KASLR disabled due to lack of seed Example of success (on a NanoPi R4S): [ 0.078587] KASLR enabled How Has This Been Tested?

The challenge with TinyML is to extract the maximum performance/efficiency at the lowest footprint for AI workloads on microcontroller-class hardware. The TinyML-CAM pipeline, developed by a team of machine learning researchers in Europe, demonstrates what’s possible to achieve on relatively low-end hardware with a camera. Most specifically, they managed to reach over 80 FPS image recognition on the sub-$10 ESP32-CAM board with the open-source TinyML-CAM pipeline taking just about 1KB of RAM. It should work on other MCU boards with a camera, and training does not seem complex since we are told it takes around 30 minutes to implement a customized task. The researchers note that solutions like TensorFlow Lite for Microcontrollers and Edge Impulse already enable the execution of ML workloads, onMCU boards, using Neural Networks (NNs). However, those usually take quite a lot of memory, between 50 and 500 kB of RAM, and take 100 to 600 ms [...] The post TinyML-CAM pipeline enables 80 FPS image recognition on ESP32 using just 1 KB RAM appeared first on CNX Software - Embedded Systems News.

ITEAD has sent us a Smart Home kit for review including the SONOFF NSPanel Pro Android control panel and Zigbee gateway, an enclosure stand, the CAM Slim WiFi camera, and four Zigbee modules, namely the SNZB-01 wireless switch, the SNZB-02 temperature & humidity sensor, the SNZB-03 motion sensor, and the SNZB-04 door/window sensor. In this review, we’ll configure the NSPanel Pro controller with the eWelink app in Android, show how to add the WiFi camera and Zigbee devices directly to NSPanel Pro, and go back to the eWelink app for more advanced features such as scenes with triggers and actions. Sonoff NSPanel Pro kit unboxing Let’s get started by having a closer look at the SONOFF NSPanel Pro controller. As previously noted, the device is based on Rockchip PX30 quad-core Cortex-A35 processor and runs Android 8.1. It acts both as a control panel and a WiFi to Zigbee 3.0 gateway.

Everactive has launched a batteryless IoT devkit to let engineers evaluate its ultra-low-power energy harvesting solution and the Evernet wireless protocol for the “Hyperscale” Internet of Things. The kit is comprised of two environment sensors (ENV+ Eversensor) with a low-light photovoltaic harvester, one USB Evergateway, and an unlimited number of accounts to the Everactive developer console for data visualization. The ENV+ Eversensor features temperature, humidity, and pressure sensors, as well as a 3-axis accelerometer, supports the Evernet IoT protocol, and instead of using a battery for power, the device relies on a photovoltaic cell that provides enough energy for continuous data streaming to the USB gateway at a rate of once every 15 seconds. The public details about the development kit are rather light, but developers will have access to a developer console for data visualization, the ability to sandbox data & add virtual sensors, as well as access to [...] The post Everactive launches batteryless IoT devkit using Evernet low-power protocol appeared first on CNX Software - Embedded Systems News.

Description This code have 2 issues. The argument -f ${binary:Package} will be treated as varibale. So the command is incorrent and output nothing to stdout. But debsums will check all package when we don't specify any package. So it happens to work. What's more, when we silense it by default (#4080) , we leave a } after '>/dev/null 2>/dev/null'. It's really strange how it can work. lol How Has This Been Tested?

LOLIN C3 Pico is a tiny (25.4×25.4mm) ESP32-C3 RISC-V board with 2.4 GHz WiFi and Bluetooth Low Energy connectivity, a few I/Os, and LiPo battery support including charging circuitry. I tend to like Wemos/LOLIN boards, because of their small form factor, support for equally tiny shields, and low price. The LOLIN C3 Pico is no exception, and even adds a few features such as an RGB LED, an I2C connector, and support for battery power and charging.

It’s now much easier to AI features to your project thanks to better tools, but as we’ve experienced when trying out Edge Impulse machine learning platform on the XIAO BLE Sense board, it still requires some effort and the learning curve may be higher than some expect. But for common tasks like face detection, there’s no reason for the solution to be hard-to-use or expensive, and Pete Warden (Useful Sensors) has designed the $10 Person Sensor fitted with a camera module pre-programmed with algorithms that detect nearby faces and reports the results over an I2C interface. Person Sensor specifications: ASIC – Himax HX6537-A ultra-low-power AI accelerator @ 400 MHz with 2MB SRAM, 2MB flash Camera Image Sensor – 110 degrees FOV Image scan rate – 7Hz with no facial recognition Image scan rate – 5Hz with facial recognition active Host interface Qwiic connector for the I2C interface up to [...] The post Easily add face detection to your project with the Person Sensor module appeared first on CNX Software - Embedded Systems News.
