Judging criteria

Your project is judged on a 100-point scale using the following criteria.

Judges may conduct unit tests and code review. In some cases, field tests may be performed. Completeness of documentation requirements is also expected.

Documentation [25 POINTS]

How well do you describe your project in the project title, one-sentence elevator pitch, and its full story? Are the relevant resources, including code included? Documentation should include detailed instructions for your project. Can someone replicate the demo given the instructions you provide?

Video and Photos [20 POINTS]
Photographs, videos, and screenshots are worth a thousand words. How well does the video capture and demonstrate your solution? Does the video showcase what the demonstration does? Does the video show the steps needed in order to replicate the demo?

Code & Contributions [30 POINTS]

At judges’ discretion, any or all of the following will be checked: Code will be checked for meaningfulness, readability, performance, cleanness (“clang-tidy”), fake check, resource consumption and global usage possibilities. The more i.MX RT1010 peripherals that are enabled by the code, the more points that will be awarded.

Inventiveness [10 POINTS]

Does your project demonstrate innovative thinking, does it bring new solutions to an existing problem, or apply existing solutions to a novel problem?

Technical Depth [15 POINTS]

How sophisticated is the code or solution? It’s worth extra points! The more i.MX RT1010 peripherals that are enabled by the code, the more points that will be awarded.
