1. DIY design helps cultivate logical thinking and practical abilities;
2. Support your own programming and learn from it
3. Support IOS/Android App control, easy to operate
4. Use MakeCode graphical Python programming to support dual-system gyroscope calibration equipped with Super:bit
5. Tumble: The Drill Building Kit contains 315 bricks and two building motors for building balance bikes and unicycles. It is equipped with a super:bit expansion board, uses BBC micro:bit as the core controller, and uses MakeCode Editor graphics and Python programming to realize game play such as colorful lights and music whistles. Using physical self-balancing method, the gyroscope calibrates the movement posture in real time, which can keep the car balanced and walk on various terrains. Compared with other building block carts, its biggest difference is that it adopts a rubber band fixed structure, which has the characteristics of shock absorption, anti-fall, and easy buffering. In addition, it also supports Android/iOS dual system Bluetooth APP control, as well as remote control using a micro:bit handle. We will provide detailed installation tutorials and it only takes 30 minutes to complete the assembly.
