LESSON 10

ITERATE TO INNOVATE

WOULD YOU RATHER?

I’m going to read two choices.

• The goal is for you to pick one.

​

• Move to the side of the room that best aligns to your choice.

​

Sample Choice:

Fly a magic carpet OR own a personal robot?

WINDOW WASHING

Businesses everywhere are using drone-based cleaning and maintenance robotics.

WINDOW WASHING

Design Challenge: Create a lightweight attachment that lets Hopper “wash” 4-8 windows by marking a 2-inch line on each.

Think Like an Engineer:

• How can you safely attach a tool to Hopper?

​

• What materials will be light, balanced, and secure?

​

• How will you make it easy to test and modify?

​

Tip: Check that sensors and propellers are clear before flying!

WINDOW WASHING

Think Like an Engineer:

• Define safe zones.

​

• Gather approved classroom materials.

​

• Decide as a class: one large course or multiple mini-courses.

​

• Brainstorm obstacle ideas that test turns, altitude, and precision.

​

• Write out fly directions or a program in FTW Code to complete the course using loops, turns, and pauses.

​

OBSTACLE ARCHITECTS

Design Challenge: Design and code a creative obstacle course for Hopper to navigate.

• Which attachment method worked best for your washing device?

​

• What flight adjustments were necessary to hover close enough without bumping the window?

​

• What design choices made your obstacle course challenging but fair?

​

• How similar were your brainstormed designs/codes to the final versions?
