Module summary

In our everyday life we interact with mechanisms, actuators and sensors and in many instances all three elements must come together to create an interactive control system. From the simple automated door at a local supermarket or the home shower unit, through to complex systems such as ABS in your car or the flight control systems od a modern aircraft. Lives may depend on the decisions our engineers make when creating such systems and therefore an understanding of the types, characteristics and integration of such devices is paramount to the suite of engineering skills that our students should be armed with when they enter the professional world of engineering. This course attempts to broaden their knowledge and their practical experience of the most commonly used devices so that they have the foundations from which to grow from and to enable our students to communicate knowledgeably and intelligently about this significant aspect of Engineering.

Objectives

To raise the students awareness, knowledge and practical experience of mechanisms, actuators and sensors. Students will be exposed to these industrial elements via a series of lectures, workshops and labs.
In Mechanisms students will learn to critically assess mechanisms and then apply this learning to solve practical mechanical problems which require the making of functional mechanisms which will challenge and develop their problem solving, material analysis, material application and manipulation, building skills, time management and communication skills.
In Actuators students will learn about hydraulic, pneumatic and electrical actuation. Students will learn the industrial symbology of actuator elements and their associated functionality within an integrated system. The students will be able to explore, create, solve and analyse process oriented problems using one, some or all of the actuator forms learned in the teaching sessions. Students will also experience a broad range of mechanical switch technologies from a physical and practical perspective.
In Sensors students will learn about devices associated with temperature, light, proximity (infrared, ultrasonic and magnetic) and specialist semiconductor sensors associated with audio, vibration acceleration and gyros. Students will learn the basic theory and transfer characteristics of these devices and the signal conditioning required to interface such devices to microcontrollers. The students will be introduced to, and develop, the C code required to extract meaningful data from such devices.

Learning outcomes
After successful completion of the course, students will be able to:
1. Apply the knowledge learned to identify a series of practical solutions to a given mechanical problem. (EP4i) (G1)
2. Critically assess a mechanical solution from the perspective of functionality, performance, materials selection, longevity, cost and practicality. (EA2i)
3. Apply their enhanced construction and communication skills. (EP2i)
4. Analyse a simple industrial process control flow diagram and identify many of the component parts from which they could assess its functionality. (EA2i)
5. Apply practical knowledge on the use of industrial automation simulation software. (EP5i)
6. Select appropriate switching devices for a multitude of applications with a complete understanding of their operation, connectivity and characteristics. (EP4i) (G1)
7. Critically evaluate a sensor problem and determine the type of sensor or sensors required. (EP2i)
8. Perform an internet search to source multiple devices for given actuator/sensor types and determine their interface requirements and critically evaluate the sourced parts for suitability to the application from the perspective of functionality, precision, limitations, cost, environmental conditions and system integration. (EP4i) (G1)
9. Suggest and implement forms of signal conditioning, when required, on the selected parts (EA4i)
10. Interface the devices with a microcontroller and either activate or extract their fundamental data (EA4i)
11. Suggest/develop test environments to perform component analysis, calibration and testing. (EA2i)
12. Exercise personal responsibility, which may be as a team member. (G4i)

Skills outcomes
The creative use of limited material resources to solve mechanical problems based on the understanding of materials, mechanisms and components.
Knowledge and practical experience in the theory, industrial symbology, simulation, application and stimulation methods for a diverse range of actuation devices based on hydraulics, pneumatics and electrical systems.
