3 DOF Robotic Arm and Car Movement Control Using LabVIEW and NI-myRIO device (Prototype Model)

In this post I have displayed a 3 DOF robotic Arm with Car which can perform Move , pick and place objects .

If you follow my previous post i had built a RC Car controlled by TV Remote http://lookforlk.blogspot.in/2016/03/remote-controlled-car-using-arduino-uno.html

But we do not require all items just Chassis, Wheels , DC Motor(500 RPM) , L293D .

In order to control the arm and car movement I have used Labview 2015 software and myRIO kit .

Robotic Arm has 3 servo motor .Here we have used MG996R  model .

Hardware Used


  • NI-myRIO
  • 3 DOF Robotic Arm (Servos)
  • Chassis with DC Motor and Wheels (Set).
  • L293D IC or L293D Module

Software used

  • LabVIEW 2015


I hope everyone knows basic of Servo motor . Servos have 3 terminals . Vcc , Gnd and they have Pulse Width Modulation (PWM) pin to control the rotation .

L293D Module :

Basically this it used to reverse the polarity 



NI-myRIO :

NI-myRIO is used to generate and acquires signals for controlling and processing, it has an inbuilt processor and FPGA and has many re-configurable analog and digital pins.

This is the 3 Degree of Freedom Model
