Control Robotic Module using LIFA

Abstract

For years, LabVIEW has enabled engineers and scientists to develop sophisticated autonomous systems. At
its core, Lab VIEW is widely used for sensor and actuator connectivity and currently offers more than 8000 drivers for
measurement devices. Furthermore, with new libraries for autonomy and an entirely new suite of robotics-specific sensor
and actuator drivers, LabVIEW provides all of the necessary tools for robotics development. The DC Motor is an
attractive piece of equipment in many industrial applications requiring variable speed and load characteristics due to its
ease of controllability. Speed of a DC motor varies proportional to the input voltage. With a fixed supply voltage the
speed of the motor can be changed. This paper focuses on controlling the speed and direction of a Robot using PWM
technique (varying duty cycle of a square wave) and Arduino. The four different keys are assigned for the forward,
backward, left and right movement and it is controlled by using LabVIEW interface Arduino (LIFA).
