# 6.4 Docking

The second category is docking. The vessel must start off by safely docking in a berth with minimal impact, both by normal docking and parallel docking. A GPS-point will be given as location of the berth. To clarify, AR-tags are not included in this year's competition.

### Task 2.1

**OBJECTIVE**

The ASV will start at GPS point 5, approx 5m from the dock. The ASV shall then move towards GPS-point 6, located inside the berth, and dock (stay stationary) for 5 sec.

**ELEMENTS**

| Element           | Description                                       | Dimensions      |
| ----------------- | ------------------------------------------------- | --------------- |
| Berth             | Grey                                              | 2m x 2m (L x W) |
| 2 GPS-coordinates | <p>GPS-point 5 and 6<br>Provided before start</p> | N/A             |

**TASK GUIDELINE**

Step 1:

You are at the dock and it is your turn.

Step 2:

You are given the clear signal from the Chief Marshall to steer your vessel to GPS-point 5 of Task 2.1. This shall be done through Remote Control.

Step 3:

Once given the go-ahead from the Chief Marhsall, you must switch to Autonomous Mode, and your ASV may start its attempt at Task 2.1. Your turn starts when given the go-ahead.

Step 4:

Once reached GPS-point 6 inside the berth, your ASV shall stay stationary for 5 seconds, before it again exits the berth and returns towards GPS-point 5.

Step 6:

Once reached GPS-point 5 again, your attempt finishes. Then the ASV shall stay stationary there, waiting for the go-ahead to proceed. You may switch to Remote Control if needed.

### Task 2.2

**OBJECTIVE:**

The ASV will start at GPS point 5, approx 5m from the barge. The ASV shall then move towards GPS-point 7, located inside the barge, and parallell dock (stay stationary) for 5 sec.

**ELEMENTS:**

| Element           | Description                                       | Dimensions      |
| ----------------- | ------------------------------------------------- | --------------- |
| Berth             | Grey                                              | 2m x 4m (L x W) |
| 2 GPS-coordinates | <p>GPS-point 5 and 7<br>Provided before start</p> | N/A             |

**TASK GUIDELINE**

Step 1:

Once given the go-ahead from the Chief Marhsall, you must switch to Autonomous Mode, and your ASV may start its attempt at Task 2.2. Your turn starts when given the go-ahead.

Step 2:

Once reached GPS-point 7 inside the berth, your ASV shall stay stationary for 5 seconds, before it again exits the berth and returns towards GPS-point 5.

Step 3:

Once reached GPS-point 5 again, your attempt finishes. Then the ASV shall stay stationary there, waiting for the go-ahead to proceed. You may switch to Remote Control if needed.

Step 4:

When the Chief Marshall gives the go-ahead, you may steer the ASV safely back to the dock in Remote Control.

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 current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://njord.gitbook.io/physical-competition-2023/6-task-descriptions/6.4-docking.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.
