The DFRobot Maqueen Plus V3 (Sensor Edition) is an advanced BBC micro:bit-compatible STEM robot chassis that adds an onboard color sensor to the standard Maqueen feature set — enabling color-triggered robot behaviors, color-coded sorting tasks, and richer sensor-driven programming exercises. Like the Ranging Edition, it features encoder motors, 4-channel IR line following, programmable RGB LEDs, and Gravity I2C expansion ports, all controlled by a plug-in micro:bit without soldering. MakeCode and MicroPython are both fully supported. Specifications Compatible Controller: BBC micro:bit V1 / V2 Motors: 2x DC gear motors with encoder feedback Sensor Suite: Color sensor, ambient light sensor, IR line sensors (4x) RGB LEDs: Programmable RGB LEDs (headlights and underbody) Buzzer: Onboard buzzer Communication: I2C (Gravity expansion) Power: 3.7V LiPo battery (included or sold separately) Programming: MakeCode (block), MicroPython, Arduino Chassis: Acrylic / ABS two-wheel drive platform Key Features Advanced sensor edition with onboard color sensor for color-based robot behaviors Color detection enables programming responses to different floor or object colors 4-channel IR line following for multi-lane track navigation Encoder motors enable precise distance and speed control Plug-in micro:bit — insert the controller and begin programming immediately Gravity expansion for adding additional sensors to the robot MakeCode visual block editor for beginners; full MicroPython for advanced use Richer sensor set compared to standard Maqueen models — suitable for advanced lessons Applications STEM color detection and sorting robot Line-following robot with color-triggered stop/start Advanced classroom robotics with sensor integration Color-coded warehouse simulation robots Creative art projects with programmable color-reactive LEDs Science fair robotics demonstrations Introduction to sensor-driven decision programming Maker and hackathon robot base platform Package Includes 1x DFRobot Maqueen Plus V3 Sensor Edition Robot Chassis 1x Color Sensor Module Note: BBC micro:bit controller sold separately. Battery may vary by order. FAQ Q: How does the color sensor work? A: The I2C color sensor detects RGB values from the surface below or in front. Use MakeCode to read color values and program conditional behaviors. Q: Is the micro:bit included? A: No — BBC micro:bit V1 or V2 is sold separately. Q: How is this different from the Ranging Edition? A: The Sensor Edition includes a color sensor instead of ultrasonic. Choose Ranging for obstacle avoidance; choose Sensor for color-based tasks. Q: Can I add an ultrasonic sensor later? A: Yes — connect an ultrasonic sensor to the Gravity I2C or GPIO expansion ports. Q: What age is this designed for? A: Recommended for ages 10+ in STEM education, suitable up to adult maker projects.
