Product description: Maqueen Plus V3 - advanced educational STEM robot with matrix laser navigation for micro:bit - DFRobot MBT0050-AA
Maqueen Plus V3 is a modern educational robot compatible with micro:bit , designed for learning programming and participating in robotics competitions . Compared to simpler designs , it offers significantly greater movement precision, better environmental awareness, and broader expansion options . The use of a matrix laser sensor allows not only to measure distance but also to determine the location of obstacles, facilitating route planning and the implementation of more complex autonomous tasks. Furthermore, the robot utilizes built-in line-tracking and intersection-recognition algorithms , making it ideal for use in classrooms, workshops, and preparation for robotics competitions. It features a robust construction with fully removable N20 metal motors . Furthermore, a built-in voltage regulator ensures constant movement speed regardless of the AA battery charge level, eliminating program errors during long-term testing.
Main features of the micro:bit Maqueen Plus V3 robot
- Laser navigation : 8 x 8 matrix laser sensor enables precise obstacle detection and analysis of their location
- Advanced line tracking : 5 sensors and 4 intersection type recognition facilitate complex routes
- Accurate movement : encoders and PID control allow precise control of distance and steering angle
- Built-in algorithms : line tracking and intersection recognition at the chip level reduce the load on the micro:bit module
- Light sensors : 2 sensors with a range from 0 to 1023 allow you to create projects that respond to lighting
- Lighting effects : 4 WS2812 diodes and 2 RGB spotlights increase the attractiveness of educational projects
- Durable drive : 2 N20 metal motors with encoders ensure stable and repeatable operation
- Easy maintenance : detachable, bolt-on motors for quick replacement in case of damage
- Highly expandable : 14 extended GPIOs and I2C, UART and USB interfaces allow you to connect additional modules
- Stable drive operation : A dedicated voltage stabilization system for the motors helps maintain a constant speed despite a drop in battery voltage.
Programming the micro:bit robot for advanced STEM projects
Maqueen Plus V3 is designed for learning coding using the BBC micro:bit platform , making it suitable for both school education and more advanced hobby projects. Thanks to ready-made examples and built-in algorithms, you can quickly move from basic tasks to creating autonomous driving scenarios, avoiding obstacles, and analyzing sensor data. The robot supports the development of programming, automation, and logical thinking skills, while allowing you to focus on strategy instead of manually fine-tuning each basic function. This is an excellent solution for learning practical robotics in a modern STEM environment.
Improvements over Maqueen Plus V2 in the new V3 version
Maqueen Plus V3 introduces many significant changes compared to the previous version, Maqueen Plus V2. The most important is the use of a matrix laser sensor instead of a traditional ultrasonic sensor, which translates into greater measurement accuracy and improved environmental awareness. The new version also adds PID-controlled encoders , light sensors, built-in line tracking and intersection recognition algorithms, detachable motors, and a motor voltage stabilization system. These changes allow the robot to offer higher precision, enhanced functionality, and improved preparation for competition tasks and more complex educational projects.
