The Maqueen Plus V3 is a cutting-edge educational robot designed to transform STEM learning and robotics competitions for students in primary and secondary schools. It functions through a sophisticated integration of advanced sensors and control systems. Equipped with a high-performance matrix laser ranging sensor, it excels in environmental sensing and awareness. Precision motor encoders paired with PID control algorithms ensure highly accurate motion and maneuverability.
Additionally, the robot includes built-in algorithms capable of handling complex tasks such as line-following and intersection detection. These features empower educators and students to explore more dynamic, challenging, and interactive robotics applications in educational environments.
Features
Precise NavigationThe Maqueen Plus V3 features a high-precision matrix laser ranging sensor, a major upgrade over standard ultrasonic models. With accuracy around ±11mm for white targets at 20–200mm and speeds up to 60Hz in 4x4 mode, it scans a 60-degree field of view to detect and locate obstacles. This enables smart path planning and advanced obstacle avoidance for reliable autonomous navigation. |

Built-In AlgorithmsStreamline line-tracking and junction navigation with built-in algorithms. These onboard features make it easier to learn core robotics skills while enabling real-time recognition of crossroads and T-junctions. This supports more complex challenges and diverse competitions. Since these functions run independently, the main controller stays free for other tasks. |
Motor Encoders & PID ControlUnlike many educational robots, the Maqueen Plus V3 uses high-precision motor encoders and PID control for accurate motion. This eliminates trial-and-error tuning and ensures consistent, reliable navigation—ideal for both learning and competitions. |

Enhanced Light InteractionEnhanced interactivity is achieved through dual light intensity sensors, enabling functions such as light-following and automatic headlight activation. These are complemented by vivid, programmable RGB headlights and ambient lighting, which not only inspire creativity but also make the learning experience more immersive and enjoyable. |
Detachable Metal MotorsThe Maqueen Plus V3 uses rigorously tested, enclosed metal motors for reliable, smooth performance and protection against debris. Its detachable motor design allows quick replacement—ideal for demanding educational and competitive use. A built-in voltage regulator keeps speed consistent even as battery power drops, ensuring stable, uninterrupted operation. |
