5DOF Robot Arm 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. I will show you the entire process of building it, starting from designing and 3D printing the robot parts, connecting the electronic components and programming the Arduino, to developing our own Android application for controlling the Robot Arm.
Using the sliders in the app we can manually control the movement of each servo or axis of the robot arm. Also using the “Save” button we can record each position or step and then the robot arm can automatically run and repeat these steps. With the same button we can pause the automatic operation as well as reset or delete all steps so that we can record new ones.
To begin with, I designed the Robot Arm using Solidworks 3D modeling software. The arm has 5 degrees of freedom
For the first 3 axis, the waist, the shoulder and the elbow, I used the MG996R servos, and for the other 2 axis, the wrist roll and wrist pitch, as well as the gripper I used the smaller SG90 micro servos.
