Unit 57:

Mechatronic Systems


Unit code:
F/601/1416

QCF level:
4


Credit value:
15






Aim

This unit will develop learners’ understanding of a range of mechatronic systems that are used in industrial and domestic environments and enable them to produce specifications for mechatronic products.

Unit abstract

The material and topics covered in this unit will be broad-based to reflect the fact that mechatronics is, by its nature, multi-disciplinary and not confined to a single specialised area. The unit will encompass small, single component systems as well as larger systems integrating components from different engineering disciplines. It will develop a methodology that will allow learners to apply mechatronic design philosophy throughout the development cycle of a systems and products. The intention is to encourage the learner to recognise a system not as an interconnection of different parts but as an integrated module.

Learners will investigate the applications of mechatronics, considering the need for integration and the nature of mechatronic systems and products. Typical mechatronics components are examined by before learners look at the design steps and processes for mechatronic systems and mechatronic products.

Learning outcomes

On successful completion of this unit a learner will:

1       Understand the applications of a range of mechatronic systems and products

2       Understand electro-mechanical models and components in mechatronic systems and products

3       Be able to produce a specification for a mechatronic system or mechatronic product

4       Be able to apply mechatronic design philosophies to carry out a design analysis.


Unit content



1      Understand the applications of a range of mechatronic systems and products

Discipline integration: need for systems to be designed in an integrated way rather than as a collection of unrelated yet interconnected constituent parts eg constraints in size and cost of components, reduction in cost of computing power, required reduction in process delays, compatibility of connection systems

Mechatronics systems: differentiate between systems that are mechatronics in nature and those that incorporate a number of different disciplines

Industrial and consumer examples of mechatronics systems: applications eg industrial robots, computer-based production and manufacture (CNC/CAM) machines, ATMs, transportation systems, ‘fly by wire’ aircraft, suspension control on road vehicles, brake- and steer-by-wire; auto-exposure, auto-focus cameras, vending machines, domestic appliances

2      Understand electro-mechanical models and components in mechatronic systems and products

Simple mathematical models: mechanical system building blocks; electrical system building blocks; electrical-mechanical analogies; fluid and thermal systems

Sensor technologies: sensor and actuator technologies for mechatronic system eg resistive, inductive, capacitive, optical/fibre-optic, wireless, ultrasonic, piezoelectric

Actuator technologies: electric motors; stepper motors; motor control; fluid power; integrated actuators and sensors; embedded systems

3      Be able to produce a specification for a mechatronic system or mechatronic product

Standards: standards eg appropriate British, European and international standards

Required sensor attributes: phenomena being sensed; interaction of variables and removal of undesired changes; proximity of sensor to measurand; invasiveness of the measurement and measurand; signal form; ergonomic and economic factors

Actuator and sensor technologies: selection of suitable sensor and actuator technologies for mechatronic systems and mechatronic products

Controllers: selection of appropriate computer control hardware for mechatronic systems and mechatronic products eg microprocessor, PLC, PC-based, PIC, embedded controllers

4      Be able to apply mechatronic design philosophies to carry out a design analysis

Designing: the steps in a design process; comparison between traditional design methods and those designs which are mechatronics driven
