✓Lesson Snapshot
Student Objective
I can build the first prototype of a VEX mechanism and identify early stability, alignment, or motion issues.
Main Activity
Construct the mechanism frame and core motion system, then perform a low-risk hand test before powered or loaded testing.
Deliverable
Prototype progress evidence and issue log
Tools / Materials
VEX kit, hand tools, notebook, safety glasses if required, build plan
1ProblemUnderstand the challenge and why it matters.
The first prototype rarely works perfectly. The goal is to create a testable version quickly, then identify the most important issues before adding complexity.
2ConceptLearn the engineering idea or skill.
Prototype building should move from structure to motion to load. Teams should test often, keep moving parts visible, and record changes as they happen.
3ApplyUse the skill in a guided task.
Build the main frame and motion system. Check alignment, wobble, binding, spacing, and safe movement before adding full load or motor power.
4DocumentRecord your evidence and decisions.
Record what was built, what changed from the plan, what worked, what failed, and the next build priority. Include at least one photo or sketch.
5ReviewCheck quality and identify your next step.
A successful build day produces usable evidence even if the mechanism is not complete. Your issue log should guide the next work session.
