Table of Contents

Your website should document your journey through MSD, so include work-in-progress as well as latest results. Use pdf's for display whenever possible so that information is easily viewable without the need to download files and open applications. (Your EDGE file repository should still contain original editable files).

Team Vision for Integrated System Build & Test Phase

Summarize:

Test Results Summary

Summary can be found here. Due to sensor error in the attachment accelerometer testing there was an offset inherit to the data. The final average and Standard deviation do not have this, but the graphs include the offset for legibility.
