The Audio-Controlled Robotic Arm is an innovative project that allows users to control the movements of a robotic arm using voice commands. It uses a microcontroller with a speech recognition module or smartphone app to interpret audio inputs and convert them into mechanical actions.

This system can perform tasks like picking, placing, rotating, and gripping objects, making it useful for automation, assistive devices, and industrial applications.

Parts Used:

1. Microcontroller (Arduino / ESP32 / Raspberry Pi) – Controls the arm
2. Speech Recognition Module (e.g., Elechouse VR3 / Smartphone App with Bluetooth/Wi-Fi) – Processes voice commands
3. Servo Motors / Stepper Motors – Control the arm’s movement (base, elbow, wrist, gripper)
4. Robotic Arm Structure (Acrylic/Metal/3D Printed) – Mechanical frame
5. Motor Driver / PWM Controller – Drives multiple motors
6. Bluetooth/Wi-Fi Module (HC-05 / ESP8266) – Wireless command interface (if using phone)
7. Power Supply (Battery/Adapter) – Runs the system
