Description

This robot is designed using an Arduino Nano as the main controller to operate 2 continuous rotation (360°) servo motors and 2 standard (180°) servo motors. The system also supports an LED Dot Matrix, which functions as the robot’s mouth display.

The robot’s body consists of 5 main modular parts, along with additional components such as a weapon attachment. In its development, the robot is controlled using an ESP32 connected to a PS3 controller.
