I can define the functions and system architecture of a VEX ground-support system.
POE Unit 3 • Lesson 3.9
VEX Ground Support Systems
Focus question: How can a ground-support mechanism safely position, service, or release an aerospace vehicle or payload?

Lesson Targets
What You Will Be Able to Do
Ground-support system map
The architecture links operator input, controller, actuator, mechanism, safety interlock, and mission output.
Activity Flow
How the Lesson Moves
Each step builds the control-systems reasoning needed for today’s deliverable.
1. Define the support task
Identify what must be held, moved, aligned, or released.
2. Map the subsystems
Connect structure, power, controls, and mechanism.
3. Add safety logic
Define interlocks and a safe failure state.
Lesson Interactive
Ground-support system map Practice
Apply the lesson concept to an aerospace rover or VEX ground-support scenario. Use the feedback to correct reasoning before documenting the main deliverable.
Ground-Support Task
Lift a sample tray 120 mm, hold it while the rover docks, and lower it only after an operator command and a docked sensor signal.

Complete the Architecture
An interlock is logic that prevents a hazardous action unless a required safe condition is true.
Today’s Work
Main Deliverable
VEX Ground-Support Architecture
Create one focused engineering artifact that demonstrates today’s learning.
- Show the input, controller, actuator, mechanism, and supported payload or vehicle.
- Add one safety interlock and explain the system’s safe state if power or communication is lost.
