MiniRover Hardware

This is an open-source project for building a small rover robot similar to Mars exploration rovers. The repo contains everything you need to understand how the rover works and build your own: the circuit designs, the code that runs on the robot, and the mobile app to control it remotely.

The rover is built around a small computer chip called the ESP32, which is powerful enough to run WiFi and Bluetooth and handle real-time tasks like controlling motors and reading sensors. The robot can stream video from a camera back to your phone over WiFi, so you can see what it sees in real time. The hardware side includes motor controllers to make the wheels spin, distance sensors to detect obstacles, and carefully designed circuit boards that tie everything together. The firmware (the low-level software) handles the camera feed, serves video over the network, and interprets commands coming from your phone.

To use this project, you'd download the circuit design files and send them to a manufacturer to produce the printed circuit boards. You'd also order the electronic components listed in the bill of materials. Then you'd flash the firmware code (written for the Arduino development environment) onto the ESP32 chip that powers the rover. Finally, you'd install the Android app on your phone to drive the rover and view its camera feed over WiFi.

This would appeal to hobbyists, students, or anyone interested in robotics and electronics who wants a complete, documented example of a working rover system. The project provides schematics, code, and documentation so you're not starting from scratch—you can learn from how someone else solved these problems, or modify the design to add your own features. The README doesn't go into extensive detail about assembly or operation, but it gives you the core files and points you toward the key components you'll need to understand.
