![]() We do that using the write() function which simply moves the servo to any position from 0 to 180 degrees. Browse thousands of projects created by the Arduino community. In the setup section we need to initialize the servos and the Bluetooth module and move the robot arm to its initial position. String dataIn = "" Code language: Arduino ( arduino ) SoftwareSerial Bluetooth ( 3, 4) // Arduino(RX, TX) - HC-05 Bluetooth (TX, RX) int servo1Pos, servo2Pos, servo3Pos, servo4Pos, servo5Pos, servo6Pos // current position int servo1PPos, servo2PPos, servo3PPos, servo4PPos, servo5PPos, servo6PPos // previous position int servo01SP, servo02SP, servo03SP, servo04SP, servo05SP, servo06SP // for storing positions/steps int speedDelay = 20 In this tutorial we will learn how to make an Arduino Robot Arm which can be wirelessly controlled and programmed using a custom-build Android application. Then we need to define the six servos, the HC-05 Bluetooth module and some variables for storing the current and previous position of the servos, as well as arrays for storing the positions or the steps for the automatic mode. While doing this, robot control is provided by. Both of these libraries are included with the Arduino IDE so you don’t have to install them externally. Thanks to the holder, you can take the desired material from one place and carry it to another place, and also mix it with the material it receives. ![]() We shall learn how to construct and control a 6 axis robot arm via a control interface from a computer, and write pre-determined instructions for it to follow and repeat. So first we need to include the SoftwareSerial library for the serial communication of the Bluetooth module as well as the servo library. In this project we will build the basis for an automated programmable robotic arm. And at the end of this article I will post the complete source code. Arduino Robot Arm CodeĪs the code is a bit longer, for better understanding, I will post the source code of the program in sections with description for each section.

HC-05 Bluetooth Module ………………….… Amazon / Banggood / AliExpress. ![]() You can get the components needed for this example from the links below: So once we have connected everything together we can move on to programing the Arduino and make the Android app. Whichever the case, it will still work with the circuits on this project as long as the arm has four hobby servo motors. The power source must be able to handle at least 2A of current. If you have a 3D printer available, you can build your own using these designs or you can buy robot arm kits. For powering the servos we need 5V, but this must come from an external power source because the Arduino is not able to handle the amount of current that all of them can draw. ![]()
