Wigl Kit: Create your own music-loving robot (including schematics, source code, etc.)

Wigl can hear the notes of any instrument and respond with movements, lights and special dances! Wigl helps motivate children and adults to practice their instruments. By sequencing the notes, you can program special dance moves for your Wigl. This combination of right-brain creativity and left-brain logic makes it a unique robot for any home. How does WIG work? Wigl has a microphone, a microcontroller (brain) and some motors for movement. Wigl is always listening for notes, and through some complex math it can hear individual notes.

Tarocco: Open source closed-loop motor controller for non-small machines (including firmware, PCB, etc.)

Desktop CNC machines often use stepper motors, often because they do not require position feedback sensors, thus reducing system cost. But there are situations where a position feedback sensor is needed or necessary, and the power output of a stepper motor, especially at high speeds, becomes a bottleneck for those who want a better performing machine.

Robo HAT MM1: Open Source Robotics and Automation Controller for Raspberry Pi

obotics Masters Robo HAT MM1 is an open source robot controller board for the Raspberry Pi. It has an education focus but is suitable for many applications. Robo HAT provides all the hardware you need in one easy-to-use form factor. It removes the initial barriers to starting any robotics project. With support for Adafruit CircuitPython, the Arduino IDE, and other libraries, Robo HAT serves as a single solution for all projects, big or small. The Robo HAT MM1 eliminates the need to purchase a large number of individual components by including them on the board. It can act as a PWM driver, provide onboard power via a voltage regulator, and measure motion using an onboard IMU - all at the same time. Broad compatibility with many open source software platforms such as CircuitPython, SeeSaw and the Arduino IDE means you can use all existing sensor software while creating your project in a way that works best for you. The hardware schematics and software are completely open source.

STEP400: 4-axis stepper motor driver for creative encoders (schematic, PCB, source code, etc.)

STEP400 is a stepper motor driver board that can control up to 4 axes. STEP400 elegantly combines all necessary functions, from communication to motor control, into a simple and complete package. STEP400 uses Open Sound Control (OSC) based on standard Ethernet rather than specialized industrial protocols to achieve ease of use while ensuring it is reliable enough for use in art, design or any other creative application. STEP400 can be easily controlled through creative coding environments such as openFrameworks, Processing, Max, Unity or Touch Designer. STEP400 is Arduino compatible, so you can drive the motors with your own code too.

Unicycle self-balancing robot produced by Zhihuijun

This little robot is called ONE, which is actually a work UP made when he was in school five years ago. After finishing it that year, I never had time to sort out the materials. During this period, many classmates came to ask me questions related to this project. This time, I simply uploaded the materials to Github and made them open source. Open source information includes the source code of the STM32 main control and the 3D model files of the mechanical structure. The circuit source files can no longer be found due to their age. Students with basic knowledge can study it by themselves~
