+## Description
+This project achieves the mechatronic conversion of a conventional excavator into an active robotic system with 4 degrees of freedom, electronically controlled via a joystick interface. The system processes analog signals on the OX/OY axes and digital inputs to coordinate four servomotors dedicated to base rotation, main arm lifting, stick movement, and bucket actuation. The control logic integrates signal mapping algorithms and software travel limits, eliminating the risk of mechanical overstressing of the joints. The final result is a machine capable of smooth and precise movements, optimized for object manipulation in the workspace by faithfully replicating joystick commands.
+
+## Motivation
+
+I chose this project because it offers a really cool practical challenge: how to adapt electronics onto an object that wasn’t designed for it. I want to learn how to manage multiple motors simultaneously in Rust and how to accurately read signals from a joystick to control a physical mechanism.
