With the rapid growth of food delivery and e-commerce services, secure and contactless delivery systems have become essential. This project presents the design and development of an RC Delivery Robot with Theft Detection and Live Monitoring using ESP32-CAM and LoRa communication. The proposed system aims to ensure safe parcel delivery while minimizing human intervention and preventing theft. The robot section is controlled by a microcontroller interfaced with DC motors driven by an L298N motor driver for movement. An ESP32-CAM module provides real-time live video streaming, enabling remote visual monitoring through a mobile device. LoRa technology is used for long-range, low-power wireless communication between the robot unit and the remote-control section, where delivery status and alerts are displayed on an LCD. To enhance security, a vibration sensor detects unauthorized handling or theft attempts or battery voltage goes low immediately triggering a buzzer alert and sending warning messages to the remote unit. An ultrasonic sensor detects obstacles, and upon detection, the microcontroller activates blue alert lights to ensure safe navigation. Battery voltage and current are continuously monitored to provide low-battery alerts. At the destination, access to the parcel compartment is protected using a password-based locking system. A 4×4 keypad mounted on the robot allows the user to enter the password. If the correct password is entered, the solenoid lock opens for a predefined duration and closes automatically afterward. Multiple incorrect password attempts trigger an alert to prevent unauthorized access. Overall, the proposed system provides a secure, intelligent, and remotely monitored delivery solution suitable for food delivery, courier services, and e-commerce applications, combining live streaming, theft detection, obstacle avoidance, and secure access control in a single robotic platform.  

The objectives of the project include:

1. To design an RC-based delivery robot for food and e-commerce applications.
2. To enable long-range wireless control and alert communication using LoRa.
3. To provide live video monitoring using the ESP32-CAM.
4. To implement theft detection and security using sensors and alerts.
5. To ensure secure parcel delivery through a password-protected locking system.
6. To detect obstacles and provide alert indications for safe navigation.
7. To monitor battery status and display system information on an LCD.
