Made for many purposes. We show the entire building process in the second episode of our [Mine Exploration YouTube series](https://youtube.com/playlist?list=PLaeYMXxaz50m38ARcgHVo31uzsZWwj21I\&si=rmQ1LfKtyheaQD_C). {% embed url="" %} **Purpose of Trevor:** > 1. To get to the bottom of a flooded uranium mine > 2. For other explorations & filming purposes, even in strong currents At the time, we called it the "ultimate submarine", because it was the best RC submarine we could build. The requirements were: > 1. Long battery life > 2. Large thrust > 3. Good lighting > 4. Capable platform for attaching anything we want [^1]: It's very unofficial, because it means a "fat guy" in polish. Stems from the fact that it's large, heavy and akward to carry. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://repo.cpsdrone.com/trevor/introduction.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
