Introduction
During rainfall, clothes left to dry on rooftops often get wet, causing inconvenience and extra effort. To solve this problem, this project demonstrates a Rain Cloth Collector Working Model that automatically moves a shade or roof panel to protect the cloth using blades as sensors and robo motors for movement. This model is innovative, low-cost, and ideal for science exhibitions and Inspire Award projects.
Objective
- To automatically detect rainfall and prevent clothes from getting wet.
- To demonstrate mechanical and electrical automation using simple materials.
- To create an interactive and practical DIY model for science exhibitions.
Materials Required
- Cardboard or thermocol sheet – base and roof/shade.
- Small robo motors (2) – to rotate or move the roof/shade.
- Plastic or cardboard blades – to act as rain sensors.
- Miniature cloth piece – to simulate drying clothes.
- 9V battery with connector – to power motors.
- Wires, tape, glue, scissors – for assembly.
- Paints or markers – for decoration.
Video Construction Steps
- Base and Shade Setup
- Prepare a sturdy cardboard base representing the rooftop.
- Construct a movable shade or roof panel above the cloth area.
- Attach the robo motors to the sides of the shade for rotational movement.
- Blade Sensor Mechanism
- Fix plastic or cardboard blades on top of the cloth area.
- These blades act as rain sensors: when rain hits the blade, it tilts or presses down.
- The tilt completes an electrical circuit, sending power to the motors.
- Motor Connection
- Connect the robo motors to a 9V battery through the blade switch.
- Ensure that the motor moves the shade smoothly over the cloth when the circuit is activated.
- Demonstration Setup
- Place a small cloth on the base to simulate drying clothes.
- Use a spray bottle or water drops to simulate rain.
- When the blade detects rain, the shade moves automatically, covering the cloth to prevent wetting.
Working Principle
- Blades act as rain detectors.
- Motor activation moves the shade to protect the cloth.
- Circuit control ensures the motor operates only when rain is detected.
- This simulates real-life automated rooftop protection systems.
Conclusion
This Rain Cloth Collector Working Model demonstrates how simple automation and mechanical design can solve everyday problems. Using blades as sensors and robo motors, it provides an interactive and visual demonstration of protecting clothes from rain, making it an excellent project for science exhibitions and Inspire Award submissions.
