# Crafting Rules
**\[Judge Ethan]** There is no official RoboBattles kit to buy. In the spirit of sustainability, the crafting rules are designed to allow players to get creative with any LEGO® parts they already have. If your robot looks like a tornado dropped a LEGO® Store onto a petting zoo, you're on the right track. 🐇🧱🐐
1. Robots must include original, unmodified LEGO® parts.
1. No tapes, glues, or other non-LEGO® materials are allowed, except for batteries.
2. Every robot must include 1 [Technic™ Hub](https://click.linksynergy.com/deeplink?id=ijmwixbQ9tg\&mid=13923\&murl=https%3A%2F%2Fwww.lego.com%2Fen-us%2Fproduct%2Ftechnic-hub-88012\&u1=guide).

## 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, and the optional `goal` query parameter:
```
GET https://play.robobattles.com/battle/rules/crafting-rules.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
