Customers order through a website or an app, picking from a list of select suppliers and provide their location. The delivery robot will then go fetch the items at the supplier and deliver them to the customer. The project aims in designing an IOT based food delivery robot which is operated wirelessly through smart phone using IOT technology. This is the internet of things (IOT) based project, where we are particularly uses the Esp32 camera, head light and two DC motor along with l293d motor driver. The ESP32 cam will capture live data with regards to its surroundings and then send it to a particular IP address through internet. User can access this device using mobile phone and while seeing the video user will control the robotic vehicle along with headlight and door lock from webpage. This robot consists of ultrasonic sensor which uses to detect the obstacles in its path and switches ON the blue lights for alerts. This robot consists of one more feature is used to detect the theft and alerts through buzzer. After reaches the destination robot will ask the password. Use need to enter the correct password though keypad. If it is correct the door will open to collect the food after some time the door will close automatically. The status of the project will display on LCD. The main controlling device of the project is PIC microcontroller which loaded program written in embedded C language.    

The objectives of the project include:

• IOT based food delivery robot.
• Controlling robot, head light and door lock from web browser
• ESP32 camera-based surveillance system.
• Keypad based password entering system.
• Obstacle detection and switching ON the blue lights.
• Theft detection and Alerting through Buzzer.
• Visible alerts using LCD display.
• To achieve this task using PIC Microcontroller.

  The major building blocks of this project are:

• Rechargeable battery.
• ESP32 Camera.
• DC Motor with L293D driver.
• Blue light.
• Head light.
• Ultrasonic sensor.
• DC motor with l298 driver.
• Buzzer.
• Keypad.
• PIC Microcontroller.
• LCD display.

  Software’s used:  

1. Arduino IDE for compiling and dumping code into ESP32 Camera.
2. PIC-C compiler for Embedded C programming.
3. PIC kit 2 programmer for dumping code into Micro controller.
4. Express SCH for Circuit design.
