The MiniQ 4WD Cross Country is a compact, fully assembled Arduino-compatible mobile robot designed for education and learning. Built around an ATmega32U4 (Arduino Leonardo) controller, it features 4-wheel drive with higher ground clearance (25 mm) for improved off-road capability on uneven terrain.
The robot integrates WS2812 RGB LEDs, infrared transmitters and receiver for obstacle detection, light sensors, a buzzer, and soft-touch buttons. It comes with an IR remote control and can be programmed via Micro-USB using the Arduino IDE. Eight beginner-friendly lessons are available for free download, covering topics from basic buzzer control to obstacle avoidance and encoder use.

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- An encoder is a sensor that converts the rotation or position of a shaft, knob or dial into electrical signals, reporting movement as incremental steps and direction, or as an absolute position. It is used to track how far something has turned, which matters for precise positioning, speed control, repeatable movement, or using a rotary knob as an input.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
