Make It Move With Wheels

Design Brief
Design, build and program a robot that can move itself a distance of 1m, using at least one motor, wusing wheels for locomotion, and can display the distance moved.

Brainstorm
Discuss different solutions to the design brief.

How will you create motion using the LEGO elements? For example, how will you:
• Connect the motor(s) to the wheels to make the robot move?
• Attach the motor to the EV3 Brick?

How will you program the robot to move the correct distance? For example, which programming blocks will you use to:
• Turn on and turn off the motor or motors?
• Display the distance it moved?

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.

Build and Program
Now you are ready to start building and programming your solution!

As you work on your solution:

1. Describe one part of your design that worked especially well.
2. Describe one design change that you had to make.
3. What will you try next?

As you test your design solution, use the table for recording your findings.

Test and Analyze
How well does your solution satisfy the design brief? Record your data. Name the columns and rows, such as Trial Number, Distance Moved, and Observations.

Review and Revise
Take a moment to reflect on your robot solution.

Think about:
• Does the robot calculate the distance accurately?
• How do you know?
• What are some ways that others have solved the problem?

Describe two ways you could improve your robot.

Communicate
Here are some ideas:
• Create a video of your project, especially your final presentation and your robot’s performance.
• Explain some important features of your software program.
• Produce a building guide for your model by taking a series of photographs as you deconstruct it.
• Include an image of your program with comments.
• Add a team photograph!

Congratulations! What will you design next?
