Education Nano 01 - Modular Wheel-Leg Robot for STEM

It details how I designed and assembled the entire bicycled robot
Supplies


I am Frank Fu, an engineer specializing in the development of artificial intelligence and robotic education with many years of development experience. I have created a series of open-source DIY projects, such as the ES02 series of robots, which comprehensively cover the entire process from structural design, circuit wiring to programming control. My YouTube channel focuses on content like "DIY Education Nano 01" and "Open Source ESP32 DIY Robot ES02", which have attracted over 100, 000 views so far. Through these projects, I continuously validate and practice the belief that educational robots should not just be toys for display but should become real learning tools.
1. Background Introduction
Recently, I launched a new educational robot module on Kickstarter called Education Nano 01 (EN01).

This robot features an innovative modular "wheel-leg" structure that can both roll and walk, powered by a robust ESP32 microcontroller. Designed specifically for STEM (Science, Technology, Engineering, Mathematics) learners, whether you are a student, maker, or home educator, you can assemble it, and program the controls yourself, making robot education truly fun, practical, and sustainable.
2. Quick Overview of Education Nano 01: a Modular Robot Suitable for Teaching and Innovation
EN01 is a fully-featured open-source robot platform that integrates structural design, electronic control, interaction, and extensibility. It is not only suitable for classroom teaching but also can meet the needs of personal project development or robotics competitions.
You can:
▪️ Freely assemble and disassemble various modules to understand mechanical structures and electronic connections.
▪️ Use a web page or mobile phone to remotely control the robot's movement and steering.
▪️ Program to achieve complex motion logic, even endowing the robot with "emotional" expressions.
▪️ Expand sensors or other peripherals to explore advanced functions.
▪️ Access complete educational materials and open-source resources for curriculum design or independent development.
Whether you are a beginner or a developer with an engineering background, EN01 provides you with a platform truly capable of in-depth learning and repeated practice.Here is the demonstration of the EN01 robot:
3. How We Build:

A Trusted Manufacturing Partner for Quality and Speed
Bringing open-source robots to life requires not only excellent design but also reliable, scalable, and affordable manufacturing processes. That's why I've partnered with two industry-leading service companies that share our commitment to open innovation:
Affordable for small batches — perfect for educational kits
JLCPCB – High-quality, low-cost PCBs for everyone
The EN01's control board is made from ESP32-WROOM-32 module custom PCB. To ensure consistent quality and fast lead times, we use JLCPCB for the production of prototypes and low-volume PCBs.
Why Choose JLCPCB?
4-layer gold-plated circuit board ensures stable signal integrity
PCBA service (pick-and-place + soldering) reduces assembly errors
Fast 3-5 day delivery, essential for rapid iteration
The first free assembly (some components) – a great help for crowdfunding projects
JLCPCB allows us to deliver professional-grade electronics at manufacturer-friendly prices, ensuring reliable operation of every EN01.
JLCCNC – Precision mechanical parts, ready to assemble
The wheel leg structure, motor mounts, and chassis components are made of aluminum alloy and engineering plastics, which are precision machined for durability and smooth movement.
For these mechanical parts, I rely on JLCCNC, a trusted provider of CNC machining, sheet metal, and 3D printing services.
Why JLCCNC?
High-precision CNC milling ensures tight tolerances for moving parts
Anodized aluminum, high strength and beautiful appearance
One-stop ordering: Upload CAD, get a quote instantly, and receive parts within days
Using JLCCNC allows us to maintain high structural integrity while keeping costs low – and all design files (STL, STEP) will be shared so that users can order or modify parts themselves.
