✓Lesson Snapshot
Student Objective
I can describe the difference between open-loop and closed-loop control in an aerospace mission.
Main Activity
Compare timed commands with sensor-based decisions using classroom mission examples.
Deliverable
Open-loop vs closed-loop comparison chart
Tools / Materials
Notebook, projector, rover examples, VEX examples
1ProblemUnderstand the challenge and why it matters.
A mission can fail when a system follows commands without checking whether the environment changed. Timed commands are useful, but feedback can make a system more reliable.
2ConceptLearn the engineering idea or skill.
Open-loop systems run commands without using feedback to adjust behavior. Closed-loop systems use sensor feedback to compare actual behavior to a goal and make corrections.
3ApplyUse the skill in a guided task.
Sort example systems into open-loop and closed-loop categories, then explain which type would be safer or more reliable for a mission task.
4DocumentRecord your evidence and decisions.
Complete a comparison chart with examples, advantages, limitations, and one aerospace application for each control type.
5ReviewCheck quality and identify your next step.
Your chart should explain when open-loop control is acceptable and when feedback is needed.
