- What are the most significant risks that could jeopardize the success of the project? How are these risks being managed? What contingency plans are ready?
The main risk still appears to be the Bluetooth connection between each subsystem, as we are still unable to thoroughly test that. There are a few more minor issues mentioned in Jada’s status report regarding the speaker and BT module, which controls song selection and audio output; however, those will likely be solved within the upcoming week. Another risk is that the mat system has not yet been put together (physical mat, electronics, and code), so there has been no testing to see if everything works together. With time running out, we will have fewer options if we realize there is something wrong with our system and we need to change something.
No changes have been made to the system’s existing design within the past week.
Updated Schedule:
April 8 – April 15
Finish mat construction: Brooke and Jada assist when needed
Play song through lock: Jada
Order rubber covering and battery for mat for installation: Brooke
Get BT connection between app, mat, and lock: all
3D print lock housing: Jada
April 15 – April 22
Get one dance functioning on the complete system: all
Testing: all
Now that you have some portions of your project built, and entering into the verification and validation phase of your project, provide a comprehensive update on what tests you have run or are planning to run. In particular, how will you analyze the anticipated measured results to verify your contribution to the project meets the engineering design requirements or the use case requirements? Validation is usually related to your overall project and is likely to be discussed in your team reports.
Additional Discussion:
The following tests have been or will be run on the comprehensive system for validation:
- Bluetooth connection—the connections between the three subsystems will be verified by checking for a connection. This will be more rigorously tested once the system is mostly completed by checking for connection when the user with the phone app walks up to the mat and locks.
- Timing and consistency—The timing between the song and the dance detection will be tested for consistent starting. They do not need to start precisely at the same time, but they need to start consistently at the same amount of time apart. This will be done by repeatedly measuring timing.
- Backup entry – The backup entry method (keypad) will be tested for entry time (under ten seconds) using a stopwatch.
- User experience—the dance experience will be tested and reviewed by multiple third-party people to gain unbiased opinions. We have already used this type of testing to help us make decisions regarding the size of the mat, and we plan to use it to test the dance experience once we have made the mat functional.
