Picture of Arduino Robotic Arm
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


 
Enjoy;)

Step 1: Materials & Software

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

Parts:
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)

Software: 

Arduino software 0023
               NOTE: I rather use this version because the newer one gives me a lot of headaches and issues.
 
 

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..

first I would calibrate each servo.

second double check the connections

thrird it could be a faulty servo specially if is from ebay... It has happend to me before.

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?

isn't running 4/5 servos from the arduino 5v to much? shouldn't a external 5v source be used?

Thank uuuu! for solving my problem

This is great! One thing: you have servo 4 on pin 4, but the code indicates pin 5.

Cool, I'm gonna use plywood and if you want it to be more reliable, put some oogoo diy rubber, recipe at http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/
Thanks looks like a fun project.

I love the cardboard. Just for hilariousness sake, please watch this: Xbox 720

You would get a good laugh out of it. This was made without servos, so there was not really a way to gauge. 
That is cool!!!!!!!!
