Robot Arm

Introduction: Robot Arm

About: Think, make, test, write, repeat

Recently we got hold on bunch of Arduino compatible parts. Micro servos were one of those. Micro servos are very cheap, and you can easely control their position with Arduino board. After discussion what we should make with them, we agreed on simple and small robot arm, that is:

  • cheap to make,
  • quick and easy to assemble only with basic tools,
  • great for learning and experimentign with robotics.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: What You'll Need?

You'll need following parts:

  • 4 pcs. Micro servo motor
  • 5 pcs. M6x30mm screw
  • 5 pcs. M6 nut 8 pcs. M3x10mm screw
  • 2 pcs. M3 nut
  • 4 pcs. zip tie
  • Arduino microcontroller
  • Connection wires
  • 3D Printed parts

Step 2: Assembly

We have made a video of assembly so it should be very easy for you to assemble robot arm yourself. If you hit any snags, let us know in the comments bellow.

Step 3: Wiring

We are using PWM ports on Arduino Uno (same ports can be used with Nano, Pro Mini and Mega 2560). If you'd like to use our example code, please connect the motors as on wiring diagram above.

Step 4: Arduino Sketch

We made simple demo sketch for controlling our robot arm. We are using small 3D printed pallet for this demo.

Let us know what you think in the comments bellow.

    Hi,

    Thank you for sharing your work. I would like to ask what "Kaseta" is for as I

    don´t see you using it in the code. Did you have any plans for it?

    Thank you again!

    Thank you for your comment. "Kaseta" was used before other parts were developed.
