Arduino & Bluetooth Controlled Robotic Arm
this project is built using Arduino & Bluetooth module. Android application is used to control the robot wirelessly. This Robotic Arm can be operated in either manual mode or can be programmable to be operated in Fully Automatic Mode.

Proper power supply for Arduino and 4 Servo Motors
Connecting Wires
Android Phone with custom application installed
3D Printed Robotic Arm
One of the important feature of any Robotic Arm project is the aesthetics. So, we decided to go for 3D Printed Parts for the Robotic Arm. daGHIZmo designed a 3D Robotic Arm called EEZYbotARM and uploaded the files in Thingiverse website.
Working of the Arduino & Bluetooth Controlled Robotic Arm
Install the Application in your Android Phone and provide necessary permissions to access the device’s Bluetooth. If the Bluetooth Module (HC-05) is not paired with the mobile, pair it using the Bluetooth Settings of the Phone.
Once the device is paired, open the App and it will automatically list out the paired Bluetooth devices. Select the correct Bluetooth Module and if everything goes well, you will enter into the main control panel.
Here, you can see controls for the four servo motors of the Robotic Arm i.e. Base, Shoulder, Elbow and Grip. Use the arrow keys of the respective Servo motor and control the robotic arm. This part of the working is the Manual Operation of the Robotic Arm, where every movement must be manually adjusted.
Highlights of Arduino & Bluetooth Controlled Robotic Arm Project
· This Robotic Arm can be controlled using any Android based Smart Phone with Bluetooth.
· Dedicated App for Android Phone to control the Robotic Arm.
· There are two modes of operation: Manual Mode and Automatic Mode.
· For regular or manual operation, you can control the Robotic Arm by manipulating the values of individual servo motors of the Robotic Arm.
· When Programming Mode is enabled, you can program your Robotic Arm for fully automatic operation.
· The Robotic Arm contains four Metal Gear Servos and 3D Printed Parts for the structure.
