Iterating is a critical part of the design process. Students should make design iterations and prepare their final presentations, which will include running their biobot, with it's new legs, on the test rescue course.
Getting Started
Preparation Needed for the Activity:
Computers
Biobots
Student-designed legs/feet
Three part challenge course
Note: A checklist for students may be helpful in directing students to the proper place in the EDPL to update their data.
Understand: add requirements
Ideate: iterate new designs based on feedback/testing
Evaluate: add/revise requirements
Prototype & Test: design CAD, print, conduct trials
Communicate: concept review with teacher
Part 1 - Design Iterations: 50-150 min
Once the legs are printed, students should assemble their bots and conduct testing trials to determine how well the legs perform.
Students should note all results and issues that arise in the EDPL.
Students should begin the iteration process by determining if new requirements need to be considered and logging these requirements in the EDPL.
All students should attempt at least one design iteration. If timing allows, two or three iterations are better.
Every iteration should be included in their EDPL.
Prior to each print iteration, the group should meet with you to present their design brief, in preparation for the printing of the new part.
Part 2 - Final Presentations: 150 min
The presentations should include:
The bot leg final design, including the design and material choices and the number of iterations the team conducted.
The data that the team used to determine the design decisions.
They can share data from earlier testing of materials, and from recent testing data of the leg/foot design. Visuals are good.
Demonstration of their bots’ ability to complete the challenge course.
The class should record time and the distance the bot traveled, if it did not make it all the way to the victim. You will use this for comparisons to other groups
