POE Unit 3

Autonomous Rover Systems: Controls, Sensors & Fluid Power

Students explore how automated aerospace systems use logic, sensors, feedback, actuators, and fluid power to complete missions safely and reliably. VEX rover platforms and VEX ground-support systems become the platform for programming, testing, and refining open-loop and closed-loop rover behavior.

Unit Purpose

What this unit prepares you to do

Unit 3 moves from control-system logic to physical mission systems. You will plan algorithms, test rover behavior, explore feedback and sensors, use VEX or fluid power for ground support, and defend an integrated autonomous mission with evidence.

Plan control logic

Create flowcharts, mission algorithms, and decision tables that show how an automated system should behave.

Use feedback

Compare open-loop and closed-loop control by testing rover missions, sensors, thresholds, and actuator responses.

Integrate systems

Combine a VEX rover platform mission with a VEX, pneumatic, hydraulic, or physical ground-support system.

Unit Project

Rover Mission + VEX Ground Support System

Design, program, test, and demonstrate an autonomous rover mission supported by a VEX, fluid-power, or physical ground-support system. Your final design must use control logic, testing evidence, and mission performance data to justify decisions.

Possible missions

Terrain survey route, sample-site detection, payload delivery simulation, obstacle navigation, search-and-survey path, or approved custom aerospace mission task.

Support systems

VEX checkpoint gate, payload station, rotating beacon, inspection platform, signal tower, hydraulic/pneumatic door, or mission checkpoint structure.

Required evidence

Problem statement, flowchart, system architecture diagram, code screenshots, build photos, test data, iteration notes, and final design review.

Project Brief

Use this brief to guide the rover mission, control logic, VEX or fluid-power support system, testing, and final mission review.
