Arduino UNO R4 WiFi 4WD 2D SLAM Radar Robot
A four-wheel-drive autonomous exploration robot based on the Arduino UNO R4 WiFi that can navigate paths and mazes and detect surrounding obstacles. It uses a servo-mounted ultrasonic sensor to perform 180° radar scanning and transmits real-time telemetry over Wi-Fi to an interactive web dashboard, which reconstructs a 2D vector map of the surrounding walls.
