The Solar Power IoT and Autonomous Delivery Robot is designed for smart and secure material delivery using solar energy, GPS, GSM, IoT, and autonomous navigation. The robot operates in Automatic and Manual modes. In Automatic Mode, GPS-based navigation and an ultrasonic sensor help the robot reach the required destination while avoiding obstacles. In Manual Mode, the user can remotely control the robot through the web interface using ESP32 CAM by using Mobile.     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. A vibration sensor detects unauthorized movement or theft and immediately activates the buzzer.            

The main objectives of the project are:  

• Design a solar power IOT delivery robot.
• Robot that delivers food via IOT and by itself.
• GPS and GSM based self-navigation.
• Web browser-based control of a robot, a headlight, and a door lock
• ESP32-based surveillance system with cameras.
• System for typing passwords based on a keypad.
• Detecting obstacles and turning on the blue lights.
• Buzzer-based theft detection and alerting.
• LCD display notifications that can be seen.
• Using a PIC Microcontroller, this task will be accomplished.
