Building a Robot Arm: Adding Control with an Arduino

This project shows you how to add control to a robot arm with an Arduino. This entire project is divided in four parts. You can read different stages on how to design the arm, the base and the mount, in the source link. The inventor has used CAD and 3D modelling. But this one here, tells you how to get the real stuff done. So, read on.

In this project, you will be controlling the stepper motors through a microcontroller. Stepper motors, in turn, are controlling the movement of the arm. You could control them using Raspberry Pi, but in this, the inventor has used, Arduino. He has his own reasons to use Arduino, you can read more about it in the source link. You also need a breadboard so that you can keep testing after every step. You can start with the H-bridge, which is a type of stepper motor driver. Then you can start wiring the breadboard and Arduino. For this, you can get the schematic diagrams, in the source link. Connect the motor and Arduino to the H-Bridge.

And then comes the coding. You can get the source code from the link below.

Have fun and do share your robot arm with us. And if you plan to use Raspberry Pi, sharing is caring!
