How the Waterproof Action Camera Drone 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.
- Motion is transmitted through camera module, which set the speed, torque and direction at the working end.
- The Camera module captures images or video for recognition and monitoring.
- The PIR motion sensor detects human movement from the change in infrared heat.
- The Real-time clock keeps the date and time, even when power is off, for scheduling.

Mechanical viva questions on this project
What is the aim of the Waterproof Action Camera Drone project?
A waterproof drone for filming in rain and over water. Its sealed body protects the electronics, and an action camera mount captures footage in wet conditions.
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. Motion is transmitted through camera module, which set the speed, torque and direction at the working end. The Camera module captures images or video for recognition and monitoring. The PIR motion sensor detects human movement from the change in infrared heat.
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.
How does a PIR sensor detect motion?
It has two pyroelectric elements that see infrared from different zones. When a warm body moves across them, the difference changes and the sensor gives a HIGH output.
Why use an RTC instead of the controller's timer?
The RTC keeps time on its own coin cell when the main power is off and is far more accurate (DS3231 drifts about 2 ppm), so schedules stay correct.
Why is mild steel used for the frame?
It is cheap, strong, easy to cut and weld and widely available. A frame of 25 mm square pipe is enough for most student models.
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 ₹22,700 to ₹33,400, 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.
