Résumé: The project is inspired by the Curiosity Mars rover and the growing need for remote controlled surveillance devices. From bomb disposal robots to Mars rovers, we need robots that we can send on risky missions instead of humans. A robot does not need food or sleep and it can do many things that a human cannot : it can withstand harsh conditions such as extreme temperatures or high levels of radiation.

The car is built using a robot car kit with 4 motors,4 wheels and connectors,an ESP32 cam module,a L298N motor driver module, 8×1.5V batteries and the supports for the batteries, double sided tape, jumper wires and female to male and female to female wires. After assembling everything according to the diagram below, I took the ESP32 cam module out and assembled a circuit for the code upload using a breadboard, an arduino uno and a few jumper wires, the diagram for the code upload is below, in the Hardware Design section. After reconnecting the ESP32 cam module, I connected the batteries to the car. The car captures video footage using the camera present on the car and it sends the footage to my mobile phone using WebSocket through Wi-Fi connection. The mobile application created can adjust the speed of the car and the light of the flashlight present on the cam module.
