Work toward the lesson goal: Predictive Maintenance & Motor Health. Use the directions and success criteria in the activity below.
Materials
For the online work: a browser and your engineering notebook. Follow the activity’s materials list for any physical build, and get teacher approval before using equipment.
Plan your time
Suggested work block: 45–60 minutes. Physical builds and projects may span several classes; follow your teacher’s schedule.
Learning Targets
By the end of this lesson
Differentiate reactive, preventive, and predictive maintenance.
Interpret motor temperature, velocity, and current data.
Identify combinations of measurements that may indicate developing faults.
Use a manufacturing data set to look for failure patterns.
Equipment & Systems
What you will use
VEX CTE Workcell
VEXcode EXP Console
Motor-data program
Wafer-transfer-robot data set
Spreadsheet software
Student Workflow
What You Will Do
Run the provided motor-data program and establish normal workcell behavior.
Interpret changes in temperature, current, and velocity under different conditions.
Identify combinations of signals that deserve operator attention.
Analyze the wafer-transfer-robot data set for patterns associated with reduced reliability or missed pickups.
Propose a simple predictive-maintenance rule based on evidence.
Programming Focus
How coding supports the lesson
Use the VEXcode Console as a data source. Programming supports data collection; the primary skill is diagnosing patterns rather than writing new control structures.
