Use this video to:
Design, build, and program a robot that can move itself:
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.
Make It Move Discussion
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, Distance Moved, and Observations.
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.
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 Walker Bot Solution is one example of many possible solutions for the Make It Move Without Wheels project.
Sample Solution Building Ideas
The Walker Bot Example Solution combines these Building Ideas: EV3 Frames, Leg 1 and a mirror-image of Leg 1 for a set of right and left legs.
Leg 1 Building Ideas shows how to change the rotary motion of a motor to reciprocating motion.
Sample Solution Program
The motors are set for the reverse direction because the motors are actually mounted upside down in this model.
• Understand that engineers design to satisfy a need
• Put into practice teamwork and communication skills such as listening to others and justifying decisions based on evidence
• Build their own robot that can move forward using some mechanism other than wheels
• Write a program that makes their robot move at least 30cm
• Become familiar with the importance of balance (center of mass) in a structure
