Working Principle of Pragyan Rover Lite:

The "Pragyan Rover Lite" operates on a sophisticated yet user-friendly system designed to replicate key features of a lunar rover, in tribute to the Chandrayaan 3 mission. Here is a breakdown of its working principle:

1. Obstacle Avoidance using Ultrasonic Sensor:
   - The ultrasonic sensor emits high-frequency sound waves, which bounce off objects and return as echoes.
   - By measuring the time taken for the echo to return, the rover calculates distances to obstacles in its path.
   - Based on this data, the Arduino UNO processes commands to maneuver the rover, ensuring safe navigation by avoiding obstacles.

2. Environmental Monitoring with DHT11 Sensor:
   - The DHT11 sensor continuously senses ambient temperature and humidity.
   - The collected data is displayed in real-time on the rover's interface, mirroring the Pragyan rover's ability to monitor lunar environmental conditions.

3. Moisture Detection with Soil Moisture Sensor:
   - The soil moisture sensor is embedded in the lunar soil simulation.
   - It measures soil moisture levels and visually indicates the presence of water, simulating the Pragyan rover's search for water ice on the Moon.

4. Solar Tracking System for Energy Optimization:
   - The solar tracking system consists of servo motors and solar panels.
   - The system constantly adjusts the solar panels' orientation to follow the sun's path, ensuring optimal exposure and energy generation, much like the Pragyan rover's reliance on solar power.

5. Control and Programming via Android Mobile:
   - The Arduino UNO is programmed to accept control commands via an Android mobile device.
   - The mobile device communicates with the rover through the data cable, allowing users to direct its movements and receive real-time data updates.

6. Structural Components and Materials:
   - The rover's structural components are made from cardboard, wood frames, and other materials, creating a durable and lightweight chassis.
   - Components are secured using a combination of glue, super glue, nails, and double-sided tape.

The working principle of "Pragyan Rover Lite" encompasses the integration of sensors, control systems, and structural elements, with a focus on emulating key features of the Pragyan rover in a scaled-down model.
