POE Unit 1 • Lesson 1.14

Concept Sketching and Mechanism Planning

Focus question: How does a build plan make a mechanism easier to construct, test, and improve?

Lesson Targets

What You Will Be Able to Do

Learning Target

I can create a mechanism plan that shows parts, motion, inputs, outputs, and how the design will be tested.

Evidence

Labeled mechanism sketch and build plan

Success Looks Like

The plan communicates geometry, components, motion, interfaces, dimensions, assembly order, and how the concept will be tested.

Activity Flow

How the Lesson Moves

This page highlights the lesson elements you need for practice, evidence, and submission.

1. Sketch the motion path

Show input, transmission components, output, and direction of movement.

2. Plan interfaces

Label shafts, supports, fasteners, spacers, attachment points, and critical dimensions.

3. Plan the build and test

Identify assembly order, likely failure points, and the first verification test.

Lesson Interactive

Audit a Mechanism Build Plan

Select every item that a second team would need to build and test the concept without guessing.

Concept Package

The sketch shows the general shape and lists the motor and gears, but the team must decide what additional information is essential before building.

A useful engineering sketch communicates geometry, motion, interfaces, and verification—not just appearance.

Required Additions

Choose information needed to manufacture, assemble, move, and verify the concept.
Today’s Work

Main Deliverable

Labeled Mechanism Sketch and Build Plan

Create a build-ready concept package for the selected rover mechanism.

  • Include at least two views or one clear isometric sketch with labels and critical dimensions.
  • Add a parts list, assembly sequence, and first-test procedure.

Mission Debrief

1

One way today’s lesson connects to an aerospace mechanism or VEX rover system.

2

One type of evidence you could use to support a design decision.

3

One question you still have about mechanisms, energy, power, or the Unit 1 challenge.
