Module information on this degree can be found below, separated by year of study.

The module information below applies for the current academic year. The academic year runs from August to July; the 'current year' switches over at the end of July.

Students select optional courses subject to rules specified in the Mechanical Engineering Student Handbook,  for example at most three Design and Business courses. Please note that numbers are limited on some optional courses and selection criteria will apply.

Mechatronics 2

Module aims

This module will demystify electronics and control through hands-on experience of building electronic systems and of using the instrumentation needed to see how they behave. It will develop understanding of, and an ability to use, some of the analogue electronic stages used in instrumentation and control systems - in particular: 'front ends' which generate voltage signals from changes detected by sensors, stages for processing (e.g. adding, differentiating or filtering) these signals and circuits for amplifying signals to drive output devices (e.g. a meter, motor or switch).

ECTS units: 5

Learning outcomes

Recall the principal terminology, concepts and circuit symbols of simple analogue electronic instrumentation and actuator-drive systems;

Translate simple problems involving mechatronic control systems into a form which can be solved using standard mathematical methods;

Describe the operation and limitations of a digital control system with analogue inputs and outputs;

Solve problems involving current and voltages in basic semiconductor networks;

Manipulate problems of system response using the language of block diagrams, transfer functions and Bode plots;

Measure the behaviour of simple analogue and digital electronic systems and systematically debug them;

Design simple controllers to regulate the behaviour (e.g. motor speed and motor position) of a mechatronic system;

Work effectively in a small group to construct, test and program a simple mechatronic control system.
