The mechanical part of the robot arm is designed by combining the pre-selected parts appropriately. In doing so, servo motor inputs, Arduino pin inputs, and communication circuit elements are used. Any other help or issues you have feel free to let me know and I will be glad to help all of you. Robot Arm Control The connection box is made to distribute the 5V voltage from the supply source to the servo motors. They are good for testing purposes though. The micro servos used in here are the cheap ones from Ebay.

(I did this project with 4 Parallax standard servos with no vibration issues at all). This happens because of the combination of micro servos and standard servos. There is a vibration from one of the servos. Connections have to be tight from the joystick to the bread board. Take out the joystick and reconnect it again in the bread board by pressing it down to make sure it is connected. I double check the connections and the servos wont move. You have to disconnect the usb from the board to verify connections try to review the connections on the steps 5 -8. It means that either U/D+ or L/R+ are not properly connected.

When I upload the code to the board the servos, they start vibrating. Check the connections, remember in this tutorial we use PWM pins for the servos and the Analog pins for the joysticks. THE CODE: (ALWAYS TEST THE CODE BEFORE UPLOADING TO THE ARDUINO) #include const int servo1 = 3 // first servo const int servo2 = 10 // second servo const int servo3 = 5 // third servo const int servo4 = 11 // fourth servo const int joyH = 2 // L/R Parallax Thumbstick const int joyV = 3 // U/D Parallax Thumbstick const int joyX = 4 // L/R Parallax Thumbstick const int joyP = 5 // U/D Parallax Thumbstick int servoVal // variable to read the value from the analog pin Servo myservo1 // create servo object to control a servo Servo myservo2 // create servo object to control a servo Servo myservo3 // create servo object to control a servo Servo myservo4 // create servo object to control a servo void setup() ġ. In other words use this tutorial to built you own and better robotic arm. No criticism will be taken personal nor because the construction and materials used for the robotic arm. And this tutorial is to help out other Arduino users on their personal projects. I have use simple and cheap materials for this project.

NOTE: The construction of this robotic arm is for examples purposes only. And like my other Arduinos Instructurables all the electronic parts were bought RADIOSHACK, except for the micro servos.

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. I will guide you step by step using simple construction parts. This tutorial is in particular to help out another Arduino user 'RobotZee'. It is very similar to my '2 Servos + Thumbstick' instructurable. 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.
