E&TC / ECE viva questions on this project
What is the aim of the Autonomous Theft Proof Delivery Robot For Food & Ecommerce project?
A delivery robot for contactless food and parcel delivery. The four-wheel-drive robot is driven remotely using a live camera feed, carries the order in a locked compartment that only the customer can open, and announces its arrival through a speaker.
Explain the working of your project in short.
12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V. The Ultrasonic sensor measures distance to an obstacle or a liquid surface using sound echoes. The Camera module captures images or video for recognition and monitoring. The Raspberry Pi 4 runs Linux and the main program, handles the camera, networking and heavier processing such as image recognition.
Why did you choose a Raspberry Pi instead of an Arduino?
The Raspberry Pi is a full computer with an operating system, so it can run Python, OpenCV and a web server. An Arduino is a microcontroller that is better for simple real-time control but cannot process images or run multiple programs.
How does the ultrasonic sensor measure distance?
It sends a 40 kHz pulse and measures the time until the echo returns. Distance = (time × speed of sound 343 m/s) ÷ 2. The HC-SR04 works from 2 cm to about 4 m.
How is the camera image processed?
Frames are captured and processed with OpenCV: converted to grayscale, filtered and passed to a detection or recognition model that labels faces, objects or number plates.
Why is a geared motor used?
The gearbox reduces speed and multiplies torque, so a small DC motor can move a vehicle or mechanism smoothly. Torque increases roughly by the gear ratio.
Why is a resistor connected in series with an LED?
It limits the current to a safe value (about 10–20 mA). Without it, the LED would draw too much current and burn out. R = (supply voltage − LED voltage) ÷ current.
Explain the block diagram of your project.
The input section senses the real-world quantity, the Raspberry Pi 4 processes it according to the program, and the output section displays the result and drives the actuators. The power supply section feeds every block.
Which communication protocols are used between the modules?
The sensors give digital or analog signals read directly by the controller's I/O and ADC pins, and outputs are driven through transistor or relay drivers.
What is the operating voltage of the circuit?
The controller and most sensors work at 5 V (ESP boards and some modules at 3.3 V). A 12 V adapter powers the board, and a regulator steps it down. Motors and relays get their own supply line so they do not reset the controller.
Is your system open-loop or closed-loop?
Closed-loop: sensors measure the actual position, distance or condition and the controller corrects the actuators until the target is reached.
