In this instructurable I will show you how to make a simple robotic arm controlled by 4 servos , 2 analog joysticks, and an Arduino UNO. It is very similar to my "2 Servos + Thumbstick" instructurable. This tutorial is in particular to help out another Arduino user;  "RobotZee".
I will guide you step by step using simple construction parts. Remember this tutorial is to help you out and for you to have an idea on how to make your own robotic arm, using this one as an example. And like my other Arduinos Instructurables all the electronic parts were bought @ RADIOSHACK, except for the micro servos. They were bought @ Ebay. 

NOTE: The construction of this robotic arm is for examples purposes only. I have use simple and cheap materials for this project.
And this tutorial is to help out other Arduino users on their personal projects. No criticism will be taken personal nor because the construction and materials used for the robotic arm. In other words use this tutorial to built you own and better robotic arm. Thank to all of you...BI()ME(H75


Step 1: Materials & Software

Here is the list in no particular order of the parts, tools and software  needed for this project.

1.  Arduino UNO REV3
2.  (2) Bread Boards
3.  (2) Parallax servos
4.  (2) Ebay micro servos
5.  (2) Parllax analog joysticks
6.  Breadboard jumper cables
7.  Masking Tape
8.  Foam board
9.  Utility knife, scissors.
10. PATIENCE (a lot)


Arduino software 0023
               NOTE: I rather use this version because the newer one gives me a lot of headaches and issues.
<p>This has been a very fun and informative project, a great prototyping exercise. Materials: 4 x Tower Pro SG90 servos($2 each), 2 x thumbsticks ($1.80 each), electrical tape and paint sticks (call it $2). Most expensive part was the base($5)</p>
<p>hello,</p><p>I want to use this project for precision picking. Please suggest is you took any trial whith this on precised picking. I am talking about movement in mm.</p>
<p>i am using 2 micro serov with arduino controlled by joystick, but servo vibrate when i stop joytick at mid servo stop but still vibrating and vibrate at angle 0, plz help me.. </p>
<p>first I would calibrate each servo.</p><p>second double check the connections </p><p>thrird it could be a faulty servo specially if is from ebay... It has happend to me before.</p>
<p>Hi! I'm doing this for a physics fair at school, so would you mind replying with an email where i can contact you in case we face difficulties?</p>
isn't running 4/5 servos from the arduino 5v to much? shouldn't a external 5v source be used?
<p>Cool project! I'm trying to do the same...all the steps are very clear ..good job.</p>
Nice project
<p>Thank uuuu! for solving my problem</p>
<p>This is great! One thing: you have servo 4 on pin 4, but the code indicates pin 5.</p>
Keep developing pal! Great job. :)
Cool, I'm gonna use plywood and if you want it to be more reliable, put some oogoo diy rubber, recipe at&nbsp;<a href="https://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/" rel="nofollow">https://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/</a>
Thanks looks like a fun project.
Jaja nice... good one TS ;)
I love the cardboard. Just for hilariousness sake, please watch this: <a href="https://www.youtube.com/watch?v=IAFBdyKfml0" rel="nofollow">Xbox 720</a><br> <br> You would get a good laugh out of it. This was made without servos, so there was not really a way to gauge.&nbsp;
That is cool!!!!!!!!
