4. 動作モードと機能
The LAFVIN 4WD Robot Car Kit V2.0 supports multiple operating modes and functions, enhancing its versatility for various projects and learning scenarios.
4.1. Obstacle Avoidance (Ultrasound & IR)
The robot car can detect and avoid obstacles using its Ultrasound and Infrared (IR) modules. This mode allows the car to navigate complex environments autonomously.
図4.1: The robot car actively avoiding obstacles using its front-mounted ultrasonic sensor and side-mounted infrared sensors.
4.2. Line Tracking
Utilizing its tracking module, the robot car can follow a black line on a light-colored surface. This function is ideal for learning about sensor-based navigation.
