XGO-Rider is a 2-wheel self-balancing robot with an ESP32 controller plus either a Raspberry Pi CM4 or BBC Micro:bit (Crowdfunding)

XGO-Rider

XGO-Rider is a two-wheel self-balancing robot with an ESP32 controller for motor and servo control, USB-C charging, etc… and a choice between a Raspberry Pi CM4 module or a BBC Micro:bit board for display, audio, and camera (CM4-only). It’s not the first robot from Luwu Intelligence, since the company launched the XGO-Mini robot dog in 2021, followed by the XGO 2 Raspberry Pi CM4-powered desktop robotic dog with an arm which we reviewed last year. The new XGO-Rider builds on these earlier models but in a different form factor moving from four-legged robots to a 2-wheel self-balancing robot design with many of the same features including AI vision running on the Raspberry Pi CM4. XGO-Rider specifications: Host controller (one or the other) Raspberry Pi CM4 with 2GB RAM + ESP32 for main control, USB-C charging port, DIP switch BBC Micro:bit V2 + ESP32 for main control, USB-C charging port, DIP […]

The Arduino PLC Starter Kit aims to teach programmable logic control to high school and university students

Arduino PLC Starter Kit

Arduino PLC Starter Kit combines the Arduino Opta micro PLC, the Arduino DIN Simul8 digital input simulator and power distribution board, and the Arduino DIN Celsius board with two independent heater circuits and one temperature sensor acting as a temperature laboratory. The kit is supported by the Arduino PLC IDE first introduced in 2022 and comes with various cables and a power supply that allows users to quickly get started. Arduino says the kit targets the education of students aged 17 years and more. It includes 20 hours of lessons going through the history of programmable logic controllers, Modbus RS-485 communications, and how PLCs integrate with industrial simulated systems. The main hardware and software components of the kits are: Arduino Opta WiFi micro PLC based on an STMicro STM32H747XI dual-core Arm Cortex-M7/M4 MCU, offering Ethernet and RS485 communication interfaces, and exposing eight digital/analog inputs, plus four relay outputs. DIN Rail-mountable […]

The Lark Weather Station works with Arduino, ESP32, micro:bit, Raspberry Pi, and other boards

Lark Weather Station Arduino ESP32 Raspberry Pi

The Lark Weather Station measures wind speed, wind direction, temperature, humidity, and air pressure through a range of sensors and connects to popular development boards such as Arduino UNO, ESP32, BBC micro:bit, Raspberry Pi, or DFRobot Unihiker through I2C or UART. We’ve seen several projects for Internet-connection weather stations that retrieve weather data from the web and display the results locally, but the Lark Weather Station allows the users to get atmospheric data right in his/her current location thanks to its built-in anemometer, wind vane, and built-in sensors, as well as expansion interfaces for additional sensors. Lark Weather Station specifications: Storage – 16MB flash good to store about 160 days of data (when data is recorded once per minute) Sensors Compass Anemometer Wind Speed: 0.5~12m/s Cover to protect the anemometer during storage/transport Wind vane and wind direction shaft to report the wind direction (eight directions) Temperature Range –20~60℃ ±0.2℃ Humidity […]

Doly – A cute little autonomous AI-powered robot based on Raspberry Pi CM4 module (Crowdfunding)

Doly Raspberry Pi CM4 robot

Limitbit Doly is a cute little autonomous robot with two continuous tracks, two small arms controlled by servos, two round color displays acting as the eyes, and various sensors, all controlled by a Raspberry Pi CM4 system-on-module. The robot can be used for STEM (Science, Technology, Engineering, and Mathematics) education or as a developer platform. AI workloads can also run on the Raspberry Pi CM4 module taking sensors, camera, and microphone inputs, with the robot interacting with the user through the built-in stereo speaker and two eyes. In practice, that means Doly supports features such as face recognition and smart audio with the robot capable of recognizing its owner and responding to voice commands. Doly specifications: System-on-Module – Raspberry Pi CM4 Lite model CM4101000 (1GB RAM, Wireless) by default, but also supports other CM4/CM Lite modules with wireless Storage – MicroSD card slot Display – 2x high-resolution color displays (the […]

SunFounder GalaxyRVR review – An Arduino programmable Mars Rover-like robot for education

SunFounder GalaxyRVR review

SunFounder sent us a GalaxyRVR 6-wheel robot for review.
