Course unit details:
Data Acquisition & Experimental Methods (Aero)
|Unit level||Level 2|
|Teaching period(s)||Semester 2|
|Available as a free choice unit?||No|
The course has two distinct elements the theory of data acquisition and its experimental application utilising LabVIEW software and National Instrument’s hardware. The module will be delivered through a combination of ‘hands on’ LabVIEW programming sessions, lectures, resource based learning exercises and a small group project.
This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact. Please see Blackboard / course unit related emails for any further updates

Title: Design a LabVIEW program that autonomously controls a DANI robot to avoid an object placed in its path and navigate back to its starting position
The Aim of this project is to develop your skills in experimental methods and to apply your LabVIEW programming skills to developing a state machine architecture to control a robot. You will work in a group of 4 people to achieve this task.
