WHEELTEC Obstacle-Avoidance Line-Following Lidar Robot Car

The WHEELTEC Obstacle-Avoidance Line-Following Lidar Robot Car is an advanced development platform designed for students, educators, and robotics hobbyists. Available in L150 and L150 Pro configurations, this versatile robot supports secondary development and is ideal for hands-on learning in autonomous navigation. It provides a robust foundation for mastering lidar-based obstacle avoidance, tracking, and line-following algorithms.

Patented obstacle avoidance technology

This platform features a patented core technology for lidar-based obstacle avoidance and tracking under Chinese utility patent number 2022210702569.9. It comes with original video tutorials to support secondary development, making it highly accessible for educational and research purposes.

Multiple physical chassis options

The robot is available in several physical configurations to suit different terrain and motion requirements, including tracked, Ackermann steering, differential, and Mecanum wheel designs. These robust mechanical bases allow developers to test different kinematic models on a single unified platform.

Powerful STM32 core controllers

The L150 series uses the STM32F103RCT6 (C10B) mainboard, while the L150 Pro upgrades to the STM32F407VET6 (C30D) with an onboard MPU6050 IMU and integrated CAN chip. The Pro version supports up to four encoder motors and six PWM servos, expanding compatibility to Mecanum, omnidirectional, and four-wheel-drive chassis.

Comprehensive interfaces and control

The mainboard measures 85.5mm by 57.5mm, weighs 36g, and includes built-in over-temperature, short-circuit, and over-current protection. It supports ROS low-level interfaces, linear CCD or electromagnetic line tracking, and can be controlled via a dedicated mobile app or a PS2 controller.
