# Mounting

## Tips For Mounting

Included with Optii Odometry are 2 M4 x 16 mm bolts and 2 M4 nyloc nuts. The mounting holes of Optii Odometry fit into an 8 mm grid pattern.

{% hint style="success" %}
Make sure you tighten these M4 bolts well. Having a secure mounting for Optii Odometry allows it to be very rigid, improving the accuracy of your odometry readings. In addition, it helps to ensure that any knocks to the pod will not cause it to become misaligned.
{% endhint %}

When mounting Optii Odometry, the recommended height for mounting is 66 - 74 mm from the top of the mounting plate, to the bottom of your drive wheels. These heights ensure that even with tile sink, Optii Odometry will have room to travel freely and have proper traction with the floor.

## Mounting With Gobilda

Optii Odometry is well suited to robots that use Gobilda parts as the odometry pods fit perfectly into the U-Channel and the mounting holes line up. In addition it can be lined up such that the encoder cable can slide right through the 16mm hole in the channel.

{% hint style="success" %}
Optii Odometry can be mounted in 2 directions within the Gobilda U-Channel. A great way to include Optii Odometry in your robot is by placing each of your odometry pods in a U-Channel across your robot.

{% hint style="info" %}
Please note that the spacing of Optii Odometry shown above is for promotional purposes. It is better practice to separate the parallel wheels more.
{% endhint %}

## Custom Mounting

{% hint style="warning" %}
If the mounting of Optii Odometry is not sufficiently rigid, it may affect the accuracy of readings. Make sure you secure the mounting plate to a rigid part of your robot.
{% endhint %}

Ensure you provide a hole for cable routing. Refer to [Wiring](/odometry-v1/user-guide/wiring.md) for recommended cable routing practice.

Check that the mounting height is suitable.

Cover the top of each shoulder bolt in the mounting plate. This will help to ensure the rigidity of your mounting and protect it from damage.

## 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://docs.optii.com.au/odometry-v1/user-guide/mounting.md?ask=<question>&goal=<endgoal>
```

`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.
