The Working of the DIY Mars Rover

At the heart of this rover is the ESP32 microcontroller, which integrates all components, including motors, sensors, and the wireless camera. Let’s break it down step by step:

1. Power Supply: A 1300mAh Li-Po battery powers all the components, ensuring long-lasting operation.
2. Motor System: The rover uses four DC motors controlled via the L298N motor driver, which allows precise movements for navigating rough terrains.
3. Sensors:
   • Ultrasonic Sensor (HC-SR04): Detects obstacles and helps avoid collisions by measuring the distance to objects in front of the rover.
   • DHT11 Sensor: Monitors temperature and humidity, providing environmental data.
4. Wireless Camera: Streams live footage to a remote device via Wi-Fi, helping the operator navigate the rover and monitor its surroundings.
5. Buzzer: Provides audio alerts when the rover detects obstacles or unusual environmental conditions.

With these components working together, the rover can autonomously navigate, collect environmental data, and provide a real-time video feed.
