An Arduino-based maze-solving robot using 3 ultrasonic sensors, an L293D motor driver, and 2 DC motors. The robot detects obstacles, makes navigation decisions, and autonomously traverses mazes.

Abstract: In this study, we propose an ultrasonic tactile sensor for real time ... generate pulses of ultrasound waves that travel upwards through the sensor components to the contact interface while ...

The system supports both autonomous and manual control via a Wi-Fi interface and includes onboard sensing, communication, and navigation capabilities. The project integrates an STM32 microcontroller ...
