SHS1 Robotics · Semester 1 Week 8: Robot Control Principles

Lesson notes

Learning Objectives

Indicator: 1.1.2.LI.1 - Contrast non-feedback loop systems and feedback loop systems.

By the end of the lesson, learners can:

Define a control loop and distinguish between an open loop (non-feedback) and a closed loop (feedback) system.
Identify and label the components of both non-feedback and feedback loop systems, including input, process, output, sensor, and comparator.
Compare at least three contrasting features of feedback and non-feedback systems, using everyday examples.
Classify given real-world scenarios correctly as either feedback or non-feedback loop systems, justifying their reasoning.
Work collaboratively in mixed groups to research, present, and respectfully discuss findings on one type of loop system.

Curriculum details

Strand: Principles of Robotic Systems (Strand 1)
Sub-strand: Robot Control Principles (1.2)
Content standard: 1.1.2.CS.2 - 1.1.2.CS.2 Demonstrate knowledge of fundamental control principles in automation and robotics. 1.1.2.LO.2 Classify feedback and non-feedback loop systems and demonstrate the use of logic and loop diagrams in control systems design.
Indicator: 1.1.2.LI.1 - Contrast non-feedback loop systems and feedback loop systems.
Suggested placement: Semester 1, Week 8 (Week 8 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.
Source document note: The official curriculum document has a fault in this entry, so the curriculum text above is transcribed exactly as printed:

content standard text - the page prints the content standard code as 1.1.2.CS.1, a code this sub-strand already uses for a different standard; filed as 1.1.2.CS.2

Exemplars (from the NaCCA curriculum)

Problem-Based Learning: Work in balanced mixed-abilities groups to research and present on either non-feedback loop or feedback loop systems.

Managing Talk for Learning: In a moderated discussion, learners draw out contrasting differences from their research findings and share them with the class for feedback. Encourage learners to tolerate feedback and comment on others respectfully.

Assessment (1.1.2.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 1 Recall; Level 4 Extended critical thinking and reasoning.
