{"title":"Maqueen Plus V3 - Matrix Laser Navigation STEM Robot for micro:bit","handle":"maqueen-plus-v3","url":"/products/maqueen-plus-v3","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.\n\nThe 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.\n\nKey Features\n\n\nMatrix 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\n\nBuilt-In Line Tracking – 5 line-tracking sensors with dedicated calibration button and 5 adjustable speed levels\n\nIntersection Recognition – Identifies 4 junction types (crossroad, T-shaped, right+straight, left+straight) in real time\n\nPID Motor Control – 2× N20 metal motors with magnetic encoders for precise distance and angle control\n\nDetachable Motors – Screw-fixed, easily replaceable motors to minimise downtime in classroom use\n\nRegulated Motor Power – Dedicated voltage-stabilising chip maintains consistent speed regardless of battery level\n\nRGB Lighting – 4× WS2812 ambient LEDs and 2× programmable RGB headlights\n\n14 GPIO Expansion Ports – Extend functionality with additional sensors and modules\n\nFirmware Upgradeable – Dedicated interface and button for future updates\n\nClass 1 Laser Safety – Eye-safe laser ranging sensor\n\n\nSpecifications\n\n\nPower Supply – 3.5–6V (4× AA batteries: 1.5V dry cells or 1.2V NiMH rechargeable)\n\nBattery Protection – Reverse connection protection\n\nLaser Sensor Range – 20–4000 mm\n\nLaser Accuracy (20–200 mm) – ±11 mm (white), ±12 mm (grey)\n\nLaser Accuracy (200–4000 mm) – ±5% (white), ±6% (grey)\n\nDetection Angle – 60° H × 60° V (90° diagonal)\n\nLaser Update Rate – 15–60 Hz\n\nLight Sensors – 2× (0–1023 range)\n\nInfrared Receiver – 1×\n\nBuzzer – 1×\n\nBracket Adjustment – 1-axis, 270° range (M3 thumb screws)\n\n\nIdeal For\n\nSTEM robotics education in primary and secondary schools\nRobotics competitions and challenges\nTeaching programming with BBC micro:bit\nExploring autonomous navigation and obstacle avoidance\n\n\n\nNote: BBC micro:bit and batteries are not included.
