Hugging Face’s Reachy Mini is an open-source AI robot for your computer or Raspberry Pi 5

Reachy Mini

Better known for its artificial intelligence software solutions, Hugging Face has now introduced the Reachy Mini open-source desktop robot, designed to deploy AI applications that interface with the physical world. The robot comes with a camera, microphones, and a speaker, and can move its 6 DoF (degrees of freedom) head, rotate its body, or wave its antennas. Two versions are available: The Reachy Mini Lite designed for computers running Mac, Linux, and soon Windows, and the Reachy Mini autonomous robot, powered by a Raspberry Pi 5, adding wireless connectivity, a few more microphones, an accelerometer, and battery support. Both models share most of the same specifications: The Reachy Mini is programmable in Python for now, but JavaScript and Scratch will soon be supported too.  We’re also told that over 15 robot behaviors will be provided at launch on the Hugging Face hub, so users will be able to get started […]

Raspberry Pi 5-based portable AI learning platform features 41 modules, supports Arduino Nano, RPi Pico, and Micro:bit boards (Crowdfunding)

CrowPi 3

CrowPi 3 is a Raspberry Pi 5-powered all-in-one portable AI learning and development platform with a 4.3-inch touchscreen display, plenty of plug-and-play electronic modules, a breadboard area, and support for Arduino Nano, Raspberry Pi Pico, and BBC Micro:bit MCU boards for expansion. It’s basically another take on the CrowPi 2 laptop based on the Raspberry Pi 4 with similar modules placed under the keyboard, but in a different form factor. The CrowPi 3 portable learning platform replaces the 11.6-inch Full HD display with a 4.3-inch display and does away with the keyboard, but is equipped with a more powerful Raspberry Pi 5 SBC capable of handling real-time AI tools such as ChatGPT and LLaMA (with smaller, distilled models). CrowPi 3 specifications: Main Board – Raspberry Pi 5 SBC Compatible MCU boards Arduino Nano boards BBC Micro:bit boards Raspberry Pi Pico boards Display – 4.3-inch IPS touchscreen display with 800×480 resolution […]

SO-ARM101 open-source dual robotic arm kit works with Hugging Face’s LeRobot

SO-ARM101 robotic arm with hugging face support

SO-ARM101 “Arm Servo Motor Kit” is an open-source dual robotic arm kit that works with Hugging Face’s LeRobot robotics framework and is designed to interface with NVIDIA Jetson AI modules and computers. It is an update to the SO-ARM100 DIY open-source robotic arm kit introduced last year with LeRobot framework support. The new SO-ARM101 is still comprised of leader and follower arms but features improved wiring to prevent disconnection issues previously seen at joint 3, motors with optimized gear ratios, and a few functionality where the leader arm can now follow the follower arm in real-time, which will be used for reinforcement learning (RL) where a human can intervene and correct the robot’s actions. SO-ARM101 specifications: Degrees of Freedom (DOF) – 6 per Arm Motor control Total servo – 12x STS3215 bus servos (6x for each Arm) Leader Arm 1x (7.4V) 1:345 gear ratio motor for No.2 joints 2x (7.4V) […]

Pico Indicator adds LEDs to GPIO and power signals of the Raspberry Pi Pico and compatible boards

Add LEDs to Raspberry Pi Pico GPIO

8086 Consultancy has designed a simple board called the Pico Indicator to add LEDs to the GPIO and power pins of the Raspberry Pi Pico and other boards with the same pinout. In the past, we’ve seen some educational boards like the Cytron Maker Uno RP2040 include LEDs for each GPIO that make it more visual for students, but can also help debug projects without having to connect a multimeter or oscilloscope. Most MCU boards only include a few LEDs, and that includes the Raspberry Pi Pico family, which only features one user LED. The Pico Indicator fixed that by adding 29 LEDs for use with the Pico, Pico W, Pico 2, Pico 2 W, and compatible boards to show which pins are logic level high. Pico Indicator highlights: Compatible with any board following the 2x 20-pin headers layout of the Raspberry Pi Pico 29x LED indicators GPIO – 26x […]
