MODULE DETAILS

Module 4: Actuators DMCACT604

Nominal duration: 5 weeks (60 hours total time commitment)

This time commitment includes the structured activities, preparation reading, and attendance at each webinar, completing exercises, practical assessments and proctored assessments.

It is also expected that students spend additional time on readings, personal study, independent research and learning, practicing on remote labs and required software and working on any projects and assignments.


This module covers a wide spectrum of actuators (primarily electric), including both linear and rotary actuators, and includes construction, attributes and applications. It also addresses the electronic drive systems for these actuators.

MODULE PURPOSE

The purpose of this module is for the participants to develop fundamental knowledge about the construction, attributes and applications of various types of actuators used in robotics.

MODIFICATION HISTORY Version 2.0

ASSESSMENT STRATEGY

METHODS OF ASSESSMENT

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, structured assessments, samples and questioning. This will include short answer questions on the knowledge content, the use of remote and virtual labs, and writing tasks to apply the learning to academic tasks.

CONDITIONS OF ASSESSMENT

 Assessors must:

  • hold the appropriate assessor competency standards as outlined in regulations; and
  • be able to demonstrate vocational competencies at least to the level being assessed; and
  • be able to demonstrate how they are continuing to develop their VET knowledge and skills as well as maintaining their industry currency and assessor competence.

Questioning techniques should not require language, literacy and numeracy skills beyond those required in this module. The candidate must have access to all tools, equipment, materials and documentation required.

The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Assessments will be open book assessment and may be completed off-campus. Invigilation software will be used for some assessments to ensure authenticity of work completed.

Model answers must be provided for all knowledge-based assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.
