DFRobot MBT0050x Maqueen Plus V3 micro:bit Robots
DFRobot MBT0050x Maqueen Plus V3 micro:bit Robots are advanced STEM‑focused educational platforms designed to elevate robotics learning and competition performance for primary and secondary school students. Equipped with a cutting‑edge matrix laser ranging sensor, the Maqueen Plus V3 robots offer high‑precision environmental perception with accuracy as fine as ±11mm at 20mm to 200 mm and up to 60Hz refresh rates, enabling intelligent obstacle detection, spatial mapping, and route planning far beyond the capabilities of standard ultrasonic systems. High‑precision motor encoders with PID control provide remarkably accurate movement, allowing precise steering, consistent travel distances, and reliable navigation without time‑consuming trial‑and‑error calibration (making the robots competition‑ready out of the box).
A standout feature of the Maqueen Plus V3 is the suite of built‑in intelligent algorithms, including integrated line‑tracking and real‑time intersection recognition for crossroads, T‑junctions, and more. These algorithms run independently of the micro:bit controller, freeing students to focus on higher‑level programming and strategy while the robot handles complex path‑following and decision‑making tasks automatically. With expanded hardware features such as configurable RGB lighting, light sensors, an infrared receiver, a buzzer, and multiple expansion interfaces, the platform supports diverse classroom activities. These activities include autonomous navigation to interactive, sensor‑driven projects.
Available in both AA battery and 18650 lithium battery versions, the DFRobot MBT0050x Maqueen Plus V3 micro:bit Robots provide flexible power options suitable for different teaching environments and runtime needs. A durable construction, replaceable motors, and compatibility with the micro:bit ecosystem make these robots a powerful, long‑lasting tool for hands‑on robotics education. Overall, the Maqueen Plus V3 stands out as versatile, competition‑grade learning robots that empower students to explore advanced robotics concepts with professional‑level precision and ease.
