A hands-on learning kit that lets you build a wooden crocodile equipped with an ultrasonic sensor and servo, controlled by a BBC micro:bit or ESP32 Easy Coding Board. The basswood construction is environmentally friendly, and graphical block-based programming (MakeCode and KidsBlock) makes it accessible for beginners.
The kit combines hardware assembly, sensor interaction, and coding to develop logical thinking and STEM skills. Assembly is straightforward with the included components and step-by-step tutorials.
Key Features
- Basswood Construction – Eco-friendly laser-cut wooden parts
- Ultrasonic Sensor – Distance detection for interactive behaviour
- Servo Motor – Motorised jaw movement
- Block-Based Programming – MakeCode and KidsBlock support
- Dual Board Compatible – Works with micro:bit or ESP32 Easy Coding Board
Ideal For
- STEM education and coding workshops
- Hands-on robotics and maker projects
- Learning about sensors and actuators

Jargon buster
Plain-language definitions for the technical terms used above.
- ESP32
- ESP32 is a family of low-cost microcontroller chips and modules from Espressif with built-in WiFi and Bluetooth. They support programmable firmware and over-the-air updates, and are commonly programmed with toolchains such as the Arduino core and ESP-IDF.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- servo motor
- A motor module that moves to a commanded angle rather than simply spinning freely. It matters for robotics and mechanisms because it is useful for steering, arms, gates and other parts that need controlled position.
