How the Thermal Vision RC Robotic Tank With Motion Detection works
- The mild steel frame and fabrication forms the base that carries every other part, so it is designed first from the load and size of the machine.
- The DC geared motor provides the driving motion.
- The Motor driver lets the low-current controller run the motors forward, reverse and at variable speed.
- Motion is transmitted through camera module and DC geared motor, which set the speed, torque and direction at the working end.
- The Wheels / castor wheels allow the machine or vehicle to move.
- The Raspberry Pi 4 runs Linux and the main program, handles the camera, networking and heavier processing such as image recognition.
- The Camera module captures images or video for recognition and monitoring.

Mechanical viva questions on this project
What is the aim of the Thermal Vision RC Robotic Tank With Motion Detection project?
A tracked RC robot with thermal and night-vision cameras. It patrols rough terrain over 100 metres of range, detects motion and spots heat leaks and faults.
Explain the working of your project in short.
The mild steel frame and fabrication forms the base that carries every other part, so it is designed first from the load and size of the machine. The DC geared motor provides the driving motion. The Motor driver lets the low-current controller run the motors forward, reverse and at variable speed. Motion is transmitted through camera module and DC geared motor, which set the speed, torque and direction at the working end.
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 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 can't the motor be connected directly to the microcontroller?
A motor needs far more current (hundreds of mA to amps) than a controller pin can supply (about 20–40 mA). The H-bridge driver switches the motor current and allows direction control.
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.
Which material did you select for the main parts and why?
Mild steel (MS) is used for the frame because it is strong, cheap, easy to cut and weld and available everywhere. Shafts are made of EN8 or bright mild steel for strength, and parts that do not carry load can be aluminium or acrylic to reduce weight.
What factor of safety did you take in your design?
A factor of safety of 2 to 3 is taken for static parts and 3 to 5 for parts under shock or fatigue loading. Allowable stress = yield strength ÷ factor of safety, and each part is checked against it.
How did you estimate the cost of the project?
The cost is the sum of raw material, bought-out parts, machining or fabrication and overheads. Our estimate for this model is about ₹13,800 to ₹20,300, depending on size, material and the workshop rates in your city.
Which manufacturing processes were used?
Cutting and grinding of sections, arc or MIG welding of the frame, drilling for mounting holes, turning of the shafts and fitting of bearings and the drive, followed by assembly, alignment and painting.
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.
