+## ✨ Features
+
+- **📱 Bluetooth Control:** Drive the robot manually using the custom Android app.
+- **🛡️ Obstacle Avoidance:** Autonomous navigation avoiding collisions using ultrasonic and IR sensors.
+- **🚶‍♂️ Human Following:** Automatically detects and follows a person or object in front of it.

+
+## 📱 Controller App
+
+The custom Android app is designed specifically for this robot but is highly versatile. 
+
+**Note: The app can be used individually for other microcontrollers!**
+- It sends simple character commands via standard Serial over Bluetooth.
+  - Examples: `M` for Manual mode, `Y` for Obstacle mode, `Z` for Follow mode.
+- You can easily pair it with any HC-05 or HC-06 Bluetooth module connected to your own custom Arduino, ESP32, STM32, or Raspberry Pi Pico projects.
