Control Robotic Arm with Zio Modules (Part 4)

This blog post is part of the Zio Robotics Series.

Introduction

This is the Final installment of ‘Control a Robotic Arm with Zio’ post. In this tutorial, we will add another part to our Robotic Arm. Previous tutorials do not include a base for the arm to rotate. 

You can check other series of the Tutorial below:

• Control Robotic Arm with Zio Part 1
• Control Robotic Arm with Zio Part 2
• Control Robotic Arm with Zio Part 3

1. Project Overview

Difficulty Level:

Zio Padawan

Helpful resources:

You should have a basic understanding of how to install Zio development boards. In this tutorial, we assume that your development board is already configured and is ready to be set up. If you haven’t configured your board yet check out our Zio Qwiic Start Guide tutorial below to get started:

• Zio Zuino M UNO Qwiic Start Guide

Hardware:

• Zio Zuino M UNO
• Zio 16 Servo Controller
• Zio DC/DC Booster
• 3.7V 2000mAh Battery
• Robotic Arm

Software:

• Arduino IDE
• Adafruit PWM Servo Driver Library
• PS2 Arduino Library

Cables & Wires:

• 200mm Qwiic cable
• Male to Female Jumper Wires

2. Schematics

Below is the Wiring Schematics of the Robotic Arm Part 4 Project

3. Robotic Arm Code

We will be using the PS2 Arduino Library to code our PS2 Wireless Controller to work with our Robotic Arm. You can find and download the source code for this Robotic Arm Part 2 project on our Github page.

Installing Library

Download and install the following libraries and save it on your local Arduino IDE libraries folder:

• Adafruit PWM Servo Driver Library
• PS2 Arduino Library

To install the libraries open your Arduino IDE, go to Sketch tab, select Include Library -> Add.Zip Library. Select the above libraries to be included on your IDE.

Arduino has a handy guide on how to install libraries to your Arduino IDE. Check them out here!

Download Source Code

Open Arduino IDE

Download the Code for this project here.

Run your code.

4. Control Settings of the Robotic Arm

Note: Before you can control your Robotic arm with the PS2 Controller check the following steps:

• Switch on your PS2 Controller. Check that the Mode LED lights up. If it doesn’t, press the Mode button on your controller.
• After doing the above, you need to press the reset button on your Zuino M Uno for it to read your controller settings.

That’s it! You now can control the Robotic Arm with your PS2 Controller using Zio Modules.
