5.Why Must We Create EN01?
The Education Nano 01 (EN01) wasn’t created just to be “a moving robot.” It is a response to the current state of educational technology and an exploration of future learning methods. It integrates a deep understanding of market pain points, practical teaching considerations, and my personal long-term belief as a researcher and educational promoter. We believe that EN01 is a truly necessary robotic tool, and the reasons can be summarized in five key aspects:
5.1 In-depth Insight into Educational Reality: Existing Robotics Products Are “Not Enough”
Through continuous communication with frontline teachers, maker communities, and home educators, we’ve identified the following pain points in existing educational robots:
▪️ Limited functionality, only suitable for basic demonstrations, unable to support in-depth teaching
▪️ High cost, making it difficult to enter ordinary schools or homes
▪️ Closed systems, not supporting DIY expansion, teaching customization, or cross-platform development
Meanwhile, the actual educational demand is continuously rising: Teachers need reusable teaching tools, students need a truly hands-on project platform, and makers want a “detachable, modifiable, and controllable” robotic system. EN01 is a systematic response to these issues.
5.2 Balance of Structure and Interaction: Wheel-Legs Are Not a Gimmick, They Are an Educational Design
The “wheel-leg structure” of EN01 is not just an innovative shape but an educationally oriented engineering choice. We hope it can display the “fun” of bionics while possessing the “operational efficiency” of wheeled robots.
This hybrid design brings two core advantages:
▪️ Lively appearance, easy to attract student attention and spark interest
▪️ Precise driving, sensitive control, suitable for programming experiments and structural teaching
We not only hope children can see an interesting robot but also understand how it operates and try to modify it themselves.
5.3 High Adaptability to Teaching Scenarios: From Classroom to Home, From Demonstration to Development
EN01 is not designed for a single use case but is instead functionally laid out from the “places where education truly occurs”. We position it as a “desktop learning platform“, allowing it to deliver value in various settings:
▪️ In school classrooms, it can undertake assembly, control, programming, and other teaching tasks
▪️ In maker spaces, it is an ideal project for training and competition platforms
▪️ In home education, it is lightweight and easy to control, supporting remote learning and parent-child co-creation
Whether you are a teacher, parent, or student, EN01 can adapt to your learning environment.
5.4 Real Operability + Open Design: Building the Gateway to Continuous Learning
One of the most important features of EN01 is that its “openness” is not just a slogan but practically usable:
▪️ Firmware code is open source
▪️ Structural drawings are open source (CAD/STL)
▪️ Circuit diagrams and BOM lists are open source
▪️ Teaching documents and control examples are fully open
Through such open design, we hope:
▪️ Students can not only “use” the robot but also understand its underlying operating mechanism
▪️ Teachers can integrate it into custom courses, expanding teaching possibilities
▪️ Makers can develop it further to build their own versions
EN01 serves as a bridge—from “product user” to “system creator.”
5.5 Future of Education: True Learning Is Practice-Driven
The design philosophy of EN01 stems from a core understanding I developed over years in robotics development and teaching work: the most profound learning comes from the process of hands-on construction and debugging.
Unlike the passive approach of “watching videos and doing exercises,” EN01 encourages users to solve problems, construct understanding, and stimulate creativity through hands-on practice. This “practice-driven” learning experience not only imparts skills but also cultivates crucial future-oriented abilities: modeling, logic, collaboration, and systematic thinking.
I always believe the mission of education is not to indoctrinate but to empower. What EN01 offers is not to replace teachers or books but to provide every learner with an approachable, graspable, and continuously deepening practice gateway.
