Engineering Department Master of Science (MSc) or Postgraduate Diploma (PgD) in Mechatronic Systems Engineering Programme Guide 

CJT 16/05/2007

 

 

Mechatronic Systems Engineering

Many modern technological products result from integrating mechanical, electrical and computer systems. This combination of technologies is known as mechatronic systems engineering. Here, the system may be related to the manufacture of consumer or domestic goods, communications, aerospace projects or from a wide range of other industries. All products that contain a mixture of technologies encounter similar problems in their design, implementation and commissioning. The technologies involved and the interfaces  between them must be well understood. However, such technologies are often the province of specialists who, while very competent within their own disciplines, lack a holistic view of the engineering involved. The problems that over-specialization causes to industry are beginning to become critical, particularly at higher levels in the organization, where an overview of technology is essential. The task of the mechatronic systems engineer is to understand how the different technologies can be linked together; and how the specialists in the fields involved can be formed into a project or product team. Lancaster University offers a Master of Science (MSc) or Postgraduate Diploma (PgD) course in Mechatronic Systems Engineering. It is for people who are in a position to undertake either a full-time one-year course or a part-time course over a longer period. The first of its kind in the UK when it was first introduced in 1984, the program was developed as a response to industry's clear need for engineers who can work confidently and in depth within such an interdisciplinary environment. Although long established, the course is continuously monitored and updated to take account of the latest developments in the subject, including reference to internationally leading research taking place in the Department. Furthermore, student feedback and the Department’s Industrial Advisors panel are used to inform development of the course on an annual basis.

Mechatronics combines the disciplines of mechanical and electronic engineering together with computer science.

The course provides knowledge and expertise across the whole field of engineering in:  

System Design   System Management   System Technologies







The emphasis is on product design and systems integration involving sensors, embedded microcontrollers, actuators and appropriate software techniques. The mechatronic solution, in which software and electronics may play an equal role with mechanical parts or even replace them, makes products cheaper, lighter, simpler and much more versatile. Engineers with this  background have a wide choice of engineering fields in which they can work. They are, therefore, protected from the cyclic recruitment requirements of particular industries. Who is it for?

To join the MSc, students should have a good honours degree in an engineering discipline or science. An ordinary degree, Higher National Certificate (HNC) or Diploma (HND), together with appropriate practical experience are also acceptable. The full-time course (12 months) is for people who wish to complete in one year. The part-time course (24 months) is designed for people who are currently employed in an engineering environment (or expecting to move into such employment within a short time of commencing the course) and who want to enhance their skills in developing, implementing and managing systems. Students utilise the work normally undertaken by systems engineers as part of the learning experience. In this way, it avoids disrupting the normal work of students, and through recognising the skills they have obtained within the workplace, builds on previous experience to make them more effective as engineers. It also enhances the  performance of students st udents within their company as the course progresses, so that the benefit to students and employers accrues as early as possible. Outline syllabus and structure

The course consists of six taught modules and an individual mechatronic systems engineering research project. The taught modules are taken in the period October to March (over two years for part-time students) and are examined in April / May. For full-time students, one of the six taught modules is called the Linking Project (see below for details). The individual research project normally runs throughout the course. However, for full-time students, the third term and summer vacation are totally dedicated to this project, which is  primarily assessed by a dissertation submitted in September. The Postgraduate Diploma comprises the same taught modules as the MSc but a less demanding project. The Diploma course is of 9 months duration. The part-time industry-based MSc / PgD course is taken over two years. The Linking Project is replaced by one module of equal weight, chosen from other available MEng or MSc taught modules, as agreed withstudent’s the Director of Studies.work. In this case, the individual research project is normally related to the industry-based

Modules

The content of the full-time and part-time industry based courses is similar – the full-time course structure is described in Section A and the part-time course in Section B. The course normally consists of the following taught modules or related equivalent modules: Design and Modelling of Systems Programming and Embedded Systems Mechanics and Actuators Interfacing and Integration Intelligent Systems Control Linking Project (for full-time students)

(ENGR.501) (ENGR.502) (ENGR.504) (ENGR.505) (ENGR.506) (ENGR.530)

Students may be able to take alternative modules (e.g. Advanced CAD/CAM) with the agreement of the Director of Studies. Part-time students have a free module chosen from another MSc course, including Mechanical Engineering, Safety Engineering, etc. For full-time students, each module is of two week duration, with the first week consisting of an intensive series of lectures and workshops. Part-time students have the option of only attending the formal classes during this first week, thereby minimizing any absences from their place of employment. For such students, the project work associated with the second week can be completed in their own time. Section A

Assessment (Exams) Individual  project Dissertation

The course begins with an introductory week, not formally assessed, during which initial skills and guidance are given to enable students to obtain maximum benefit from the course. The five taught modules take place between October and April. They are interleaved with  project work and case cas e studies to help build an understanding of the application of the theory learned.

The sixth module, the Linking Project, is a distinctive feature of the Lancaster MSc / PgD. Its  purpose is to allow students to demonstrate the understanding and skills acquired from the formal taught elements in a controlled fashion, so that they are prepared to undertake the individual research project. Students work in small groups on a realistic project brief that is arranged to take them through the design and evaluation of a mechatronic product or process, often in conjunction with an industrial company. Finally, each student undertakes a major individual research project. In some cases, this  project may be associated with an industrial company and it is possible that following graduation employment will be found within this company. Students are expected to use the free time between each taught module to complete a feasibility study for their project, including development of the project objectives, literature review and the preparation of a  preliminary report. However, most of the practical work takes place from April to September, starting after the examination period. Assessment

The assessment is based 50% on the six taught modules (including Linking Project) and 50% on the individual project. Most of the taught modules are assessed by 75% exam and 25% coursework, with the main exception being the Linking Project (100% coursework). The assessment for the individual project is largely based on the dissertation (80%), but also includes a feasibility study (10%), technical paper (5%) and poster (5%). The requirements for a pass are: MSc / PgD:

Aggregate mark of 50% with at least 50% in the individual individual project.

Distinction is awarded (MSc) for an aggregate mark of 70% with 70% in the project. Credit is awarded (PgD) for an aggregate mark of 60% with 60% in the project. Section B

Part Time

The first five modules (each of one or two week duration) are the same as for the full-time course, except that their delivery takes place over two years. For this reason, it is possible to make an October or January start. The Linking Project (ENGR.530) is exchanged for an option taken from other modules taught in the Department (e.g. Advanced CAD/CAM). It may be possible to exchange a further module subject to the agreement of the Director of Studies, e.g. in the area of Safety Engineering or Nuclear Decommissioning. There are examinations in April / May each year. Thus, the total time spent at the university is for up to 6 weeks in each of the 2 years, plus occasional days for research and tutorials. During the course students undertake an individual project (or a series of projects) within their companies. It is helpful if an industrial advisor can be appointed to ensure the brief is agreed and issues such as confidentiality are properly addressed. However, an academic supervisor from the Department will also be chosen. In a similar manner to the full-time course, the first stage of the project is to complete a substantial feasibility study, including

development of the project objectives, literature review and the preparation of a preliminary report. This allows for feedback to be given to the student before starting the main part of the work. The final dissertation should be submitted by the end of the two year course. Assessment

The assessment is based 50% on the six taught modules and 50% on the individual project. Most of individual the taught modules assessed by 75% exam and 25% coursework. The assessment for the project isarelargely based on the dissertation (80%), but also includes a feasibility study (10%), technical paper (5%) and poster (5%). The requirements for a pass are: MSc / PgD:

Aggregate mark of 50% with at least 50% in the individual individual project.

Distinction is awarded (MSc) for an aggregate mark of 70% with 70% in the project. Credit is awarded (PgD) for an aggregate mark of 60% with 60% in the project. Section C

Short Courses

The modules listed above are offered as stand alone short courses. courses. In general, the modules are two weeks long. The first week is usually class based consisting of lectures, tutorials and workshops. The second week of most modules is typically laboratory or computer based. In some cases the second week is in the form of a mini-project.

Sample Timetable

Most modules include a mixture of lectures, workshops (the opportunity for students to solve example problems), computer and other laboratories, mini-projects and seminars by external speakers (e.g. industrial visitors). The illustrative timetable below is included to give an idea about the structure of a taught module. However, timetables may vary considerably between modules. Note that the second week of each module is usually optional for part-time students (for whom additional problem sheets and examples can be provided). Module:  ENGR. 506 Intelligent Systems Control
