Final Presentation

For [five] weeks you have followed the Engineering Design Process: Ask, Define, Ideate, Prototype, Test. You found your user in week one and designed toward a solution for them. This presentation is the last step, Reflect. It is where you pull the whole project together and show what you made and what you learned.

This is your record of the journey. Walk through it in order. Who is your user, and what problem did they face? What did your interview and research tell you (Ask)? What criteria did your design have to meet (Define)? How did you sketch and model the motion (Ideate)? How does the math prove the arm reaches its target (Prototype)? What did testing and feedback change (Test)? What do you know now that you didn't in week one (Reflect)?

Three things separate strong presentations from weak ones.

Be specific about the motion. Your arm solves one movement for your user. "Helps with daily tasks" is a wish. "Moves the gripper from (0, 0) to (25, 15) cm to raise a cup to mouth height" is the work you actually did. Name it that clearly.

Show your criteria as measurable targets. Every design goal needs a number and a yes/no test. Not "lightweight" but "under 500 grams." Not "fast" but "finishes the move in under 3 seconds." Not "accurate" but "lands within 1 cm of the target." If you wrote vague criteria back in Define, sharpen them now.

Put real numbers in your math. Don't just show the formulas. Use your actual link lengths and target point, solve for θ1 and θ2, and show every step. If you used the Rev arm, that's L1 = 18 cm and L2 = 22 cm. Which angles put the tip on your target? What triangles are you applying the Law of Cosines to? Make sketches to show your motion path.

Use the guide below as your checklist. All eight sections are scored. Back every claim with a sketch, a number, or a calculation.

Your Final Presentation

This guide is your roadmap for the final project presentation. It's not just a list of things to do, but a way to make sure your project tells a complete story, from your first interview to your final calculations. 

You’ll choose your presentation format (slides, poster, video, infographic, or another approved format), but whatever you choose, your work should tell a complete story:

• Who you designed for

• What problem they faced

• How you used the Engineering Design Process to create a solution

• How trigonometry powered your design decisions

• How feedback helped you improve

• What you learned along the way

The checklist is your to-do list — follow it to make sure every critical piece of your project is represented. The rubric is your scorecard — it shows how your work will be evaluated, from your design solution to your math to your reflection.

Your goal: How did my work make my user’s life easier, safer, or better?

If your presentation answers that question clearly, with strong evidence, engaging visuals, and accurate math, you’ll not only meet the expectations — you’ll inspire your audience and leave them impressed with what you accomplished.
