Abstract: This paper presents the design and development of a Voice Controlled Smart Robotic Vehicle integrated with obstacle detection, GPS tracking, and an emergency alert system. The system is built using an ESP microcontroller, L298N motor driver, four 100 RPM DC motors, ultrasonic sensor, Neo-6M GPS module, DF Player Mini, and an 8-ohm speaker. The vehicle operates through voice commands such as forward, backward, left, and right, enabling hands-free navigation. An ultrasonic sensor continuously monitors the surroundings and provides voice-based obstacle alerts to enhance safety. The integrated GPS module allows real-time location tracking of the vehicle. Additionally, an emergency tactical switch is incorporated to send instant notifications to the administrator during critical situations. The proposed system combines automation, safety, and intelligent control, making it suitable for smart mobility, assistive applications, and surveillance-based environments.

Keywords: Voice Control System, ESP Microcontroller, L298N Motor Driver, Ultrasonic Sensor, Neo-6M GPS Module, Emergency Alert System, Smart Robotic Vehicle.
