## Description

The Maqueen Plus V3 is an advanced STEM educational robot platform designed for primary and secondary school students. Powered by a BBC micro:bit (not included), it combines a matrix laser ranging sensor, high-precision motor encoders with PID control, and built-in line-tracking algorithms to support everything from introductory coding lessons to competitive robotics challenges. The robot features an 8×8 matrix laser ranging sensor with a 60° field of view, enabling precise obstacle detection and intelligent route planning far beyond what standard ultrasonic sensors offer. Built-in intersection recognition identifies crossroads, T-junctions, and turns in real time, letting students focus on strategy rather than low-level sensor programming. Key Features Matrix Laser Ranging – 8×8 (64-point) laser sensor with 20–4000 mm range, up to 60 Hz update rate, and ±11 mm accuracy at close range Built-In Line Tracking – 5 line-tracking sensors with dedicated calibration button and 5 adjustable speed levels Intersection Recognition – Identifies 4 junction types (crossroad, T-shaped, right+straight, left+straight) in real time PID Motor Control – 2× N20 metal motors with magnetic encoders for precise distance and angle control Detachable Motors – Screw-fixed, easily replaceable motors to minimise downtime in classroom use Regulated Motor Power – Dedicated voltage-stabilising chip maintains consistent speed regardless of battery level RGB Lighting – 4× WS2812 ambient LEDs and 2× programmable RGB headlights 14 GPIO Expansion Ports – Extend functionality with additional sensors and modules Firmware Upgradeable – Dedicated interface and button for future updates Class 1 Laser Safety – Eye-safe laser ranging sensor Specifications Power Supply – 3.5–6V (4× AA batteries: 1.5V dry cells or 1.2V NiMH rechargeable) Battery Protection – Reverse connection protection Laser Sensor Range – 20–4000 mm Laser Accuracy (20–200 mm) – ±11 mm (white), ±12 mm (grey) Laser Accuracy (200–4000 mm) – ±5% (white), ±6% (grey) Detection Angle – 60° H × 60° V (90° diagonal) Laser Update Rate – 15–60 Hz Light Sensors – 2× (0–1023 range) Infrared Receiver – 1× Buzzer – 1× Bracket Adjustment – 1-axis, 270° range (M3 thumb screws) Ideal For STEM robotics education in primary and secondary schools Robotics competitions and challenges Teaching programming with BBC micro:bit Exploring autonomous navigation and obstacle avoidance Note: BBC micro:bit and batteries are not included.
