# Challenges Challenges are optional or required tracks that include specific criteria or resources for eligibility. They help guide participants toward specific technologies or applications. ### Hardware Challenge Examples * Wearable Tech - textiles, health monitoring * Assistive Devices - smart devices, accessible living, fall detection * IoT and Automation - smart automation * Efficient fabrication/design - minimal material use, compact housings * Using specialized hardware - integrating sponsored components, using new/recent hardware When defining challenges, encourage teams to use modular mounting solutions to keep components secure and organized. It may help improve the durability of a project, which is often tested when projects need to be moved for judging/expo. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://guide.mlh.io/hardware-hackathon-guide/challenges.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
