microbit robot v3
Print Profile(1)

Description
Due to the schedule constraints of our graduation project (running until the end of the year), updates for this robot project will be released in phases on an irregular basis. We will continue our iterative development to introduce an upgraded version in the future, featuring a more high-tech aesthetic and a more streamlined, comprehensive architecture.
🤖 About the Project
This is an open-source robot project built entirely around the Micro:bit ecosystem.
🔩 Core Hardware Architecture
- Main Controller: Micro:bit
- Driver Expansion Board: Micro:bit PCA9685 Servo Driver Board
- Servo Motors: EMAX ES08A II Mini Servo Motors
📂 Open Source & 3D Models🗺️ How to Access the 3D Models
The 3D models for this project are fully open-source on the Onshape 3D CAD platform. You can access and modify them by following these steps:
Log in and navigate to the Onshape Public Documents database.
- Type ROBOT_V3 into the search bar.
- Look for the author: 瑞陞 朱.
- Click "Create a copy" to start editing online or export the files for 3D printing.


📱 Dedicated Control APP Preview
A dedicated mobile app for controlling this robot is currently under active development!
If you cannot wait to try it out, you can also use App Inventor 2 to design and build your own custom control interface. Once the official app is ready, I will open-source the complete APP source code and project files right here. Stay tuned!
💻 Software & Coding
The robot's firmware is fully compatible with the official graphical programming editor. You can head straight to the Micro:bit MakeCode Website to program the robot's control logic. It supports Block-based coding, JavaScript, and Python, making it accessible and easy to get started.
