POE Unit 3 • Lesson 3.4

Inputs, Outputs, and Sensors

Explore rover and VEX inputs/outputs and connect each one to a mission decision.

Lesson Snapshot

Student Objective

I can identify input devices, output devices, and sensors used in control systems.

Main Activity

Explore rover and VEX inputs/outputs and connect each one to a mission decision.

Deliverable

Input-output-sensor table

Tools / Materials

Notebook, VEX rover platform, VEX controller/brain/sensors, classroom examples

1ProblemUnderstand the challenge and why it matters.

Automated systems need information before they can make useful decisions. A system that cannot sense position, distance, color, time, or contact may not know whether the mission is working.

2ConceptLearn the engineering idea or skill.

Inputs provide information to the control system, outputs perform actions, and sensors measure conditions. Sensors can be digital or analog depending on how the information is represented.

3ApplyUse the skill in a guided task.

Create a table of possible inputs and outputs for a rover mission and a VEX ground-support system.

4DocumentRecord your evidence and decisions.

Document each device, what it measures or does, and how it could affect a mission decision.

5ReviewCheck quality and identify your next step.

Your table should connect hardware choices to mission purpose.
