# Combat Robot Weight Classes

In Combat Robotics, like wrestling, there are weight classes.

## Combat Robot Classes

Combat Robots compete against other robots of the same class. Classes are categories for different weights, weapon types, and materials.

### Maximum weight per class

<table data-full-width="false"><thead><tr><th>Class</th><th>Weight</th><th data-hidden></th></tr></thead><tbody><tr><td>Fairyweight</td><td>150 grams (0.33lbs)</td><td></td></tr><tr><td><strong>Antweight</strong></td><td>1lb (455 grams)</td><td></td></tr><tr><td>Beetleweight</td><td>3lb (1361 grams)</td><td></td></tr><tr><td>Hobbyweight</td><td>12lbs / 15lb</td><td></td></tr><tr><td>Featherweight</td><td>30lb</td><td></td></tr><tr><td>Lightweight</td><td>60lb</td><td></td></tr><tr><td>Middleweight</td><td>120lb</td><td></td></tr><tr><td>Heavyweight</td><td>220lb / 250lb</td><td></td></tr></tbody></table>

{% hint style="info" %}
The Battlebots you see on TV are 250lb robots!
{% endhint %}

### Class modifiers

Robots can further be broken down into these categories:

* Full Combat
* Sportsman
* **Plastic**

For the purposes of our Plant series, we'll focus on the Antweight and Plastic classes. Antweights are 1lb combat robots. Plastics allow only certain 3D printed materials, usually PLA, ABS, and PETG. We'll dive deeper into 3D printing later, but for now just know that your robot will be 1lb and mostly 3D printed.

{% hint style="info" %}
Plant comes from Plastic and Antweight
{% endhint %}

# 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 dynamically by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://plants.cometrobotics.org/combat-robotics/combat-robot-weight-classes.md?ask=<question>&goal=<user_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 `build a script that syncs our docs to a CMS` 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.
