Use this video to:
Make a System Discussion
Design, build and program a robotic system that follows a path and communicates its position at least twice along the way.
Encourage an active brainstorming process so that students develop their conceptual understanding. For example, encourage them to:
Select the Best Solution
Describe the solution that you have agreed to build and program.
Think about examples from your brainstorming discussion. Then explain why you chose this solution for the design brief. Encourage students to describe why they have chosen this solution. That way, when students are reviewing and revising, they will have specific information to use to evaluate their solution and decide whether or not it was effective.
Build and Program
Start building and programming your solution!
As you work on your solution, make sure students keep track of:
Students can use images, video, text, sound, or weblinks to document their work.
Test and Analyze
How well does your solution satisfy the design brief?
Use a table to record data. Name the columns and rows, such as Trial Number, Expected Behavior, Actual Behavior and Changes?
Review and Revise
Take a moment to reflect on your robot solution.
Encourage students to look back at the design brief and at their own brainstorming notes and test data. Encourage a peer-review process so that each group is responsible for evaluating their own and others’ projects. This review process can help students develop skills in giving constructive feedback as well as sharpening analysis skills and the use of objective data to support an argument.
You may wish to provide students with the specific precision level to aim for (e.g., within 0.5 cm).
Here are some ideas to suggest to students:
Evaluate Design and NGSS Goals
You can use the included rubrics to evaluate skills progression of Design Engineering Projects.
The Track Rover Solution is one example of many possible solutions for the Make a System That Communicates project.
Sample Solution Building Ideas
The Track Rover combines these Building Ideas: EV3 Frames, Tracks, Color Sensor 2.
Two copies of the Tracks are built: one for the right side and a mirror image for the left side.
Sample Solution Program
• Understand that larger systems can be made from smaller systems or subsystems
• Understand that sensor feedback can be used to control systems
• Understand that robots that navigate a path represent transportation technology
• Understand that robots that communicate their position represent communication technology
Students should know how to create and download a program, and how to program a motor. Students should also know how to use sensors for feedback.
