![]() ![]() ![]() We do that using the write() function which simply moves the servo to any position from 0 to 180 degrees. 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 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. The one used in this project is the Arduino Uno R3 board. Both of these libraries are included with the Arduino IDE so you don’t have to install them externally. Consider your own arm while bearing in mind industrial robot arms. So first we need to include the SoftwareSerial library for the serial communication of the Bluetooth module as well as the servo library. And at the end of this article I will post the complete source code. 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. 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. As an Amazon Associate I earn from qualifying purchases. It can be controlled by multiple people to try and achieve a common objective. Thus, 'Muscles' the quirky robotic arm came into being. Amazon / Banggood / AliExpressĭisclosure: These are affiliate links. The project started with an idea for a series of videos that would help enthusiasts build their first robot, which then developed into, building an interactive robot with the objective of community bonding in mind. HC-05 Bluetooth Module ………………….… Amazon / Banggood / AliExpress.You can get the components needed for this example from the links below: Public repository for all resources related to the OxRAM Robot Arm project. arduino robot matlab robotic-arm Updated MATLAB OxRAMSociety / RobotArm Star 10. So once we have connected everything together we can move on to programing the Arduino and make the Android app. Robotic Arm controled by Arduino with 2 Degrees of freedom. The power source must be able to handle at least 2A of current. 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. ![]()
