SHS3 Robotics · Semester 1 Week 18: Robot Control Principles

Lesson notes

Learning Objectives

Indicator: 3.1.2.LI.1 - Test operational robots for specified tasks and observe/document identified flaws.

By the end of the lesson, learners can:

Define a test plan and state at least three key components of a functional test plan for a robotic system.
Run a specified-task test on an operational robot (or robot simulation) and record observed performance using quantitative metrics (time taken, distance covered, success count) and qualitative observations (smoothness, stability, accuracy).
Document identified flaws in a structured flaw report that states the task, the expected performance, the observed performance, and the probable cause of the flaw.
Compare test results from simulation and real-world operation and explain at least one reason why results may differ between the two environments.
Present test findings to peers in a clear oral or written summary, listening to and respecting the observations of other group members.

Curriculum details

Strand: Principles of Robotic Systems (Strand 1)
Sub-strand: Robot Control Principles (1.2)
Content standard: 3.1.2.CS.3 - 3.1.2.CS.3 Demonstrate practical skills in evaluating and improving existing robotic systems. 3.1.2.LO.3 Create test plans for testing robotic systems to uncover faults and go through an iterative fault detection and correction process to fix the defect.
Indicator: 3.1.2.LI.1 - Test operational robots for specified tasks and observe/document identified flaws.
Suggested placement: Semester 1, Week 18 (Week 18 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Talk for Learning: Through questioning, discuss test methods and metrics to assess industrial robot system agility in both simulation and in reality. Discuss test methods and associated quantitative and qualitative metrics for assessing robot system efficiency and effectiveness.
