+### DoCommand
+
+Execute model-specific commands that are not otherwise defined by the service API.
+For built-in service models, any model-specific commands available are covered with each model's documentation.
+If you are implementing your own navigation service and add features that have no built-in API method, you can access them with `DoCommand`.

+
+**Parameters:**
+
+- `ctx` [(Context)](https://pkg.go.dev/context): A Context carries a deadline, a cancellation signal, and other values across API boundaries.
+- `cmd` [(map\[string\]interface{})](https://go.dev/blog/maps): The command to execute.
+
+**Returns:**
+
+- [(map\[string\]interface{})](https://go.dev/blog/maps): Result of the executed command.
+- [(error)](https://pkg.go.dev/builtin#error): An error, if one occurred.
+
+```go {class="line-numbers linkable-line-numbers"}
+myNav, err := navigation.FromRobot(robot, "my_nav_service")
+
+resp, err := myNav.DoCommand(ctx, map[string]interface{}{"command": "dosomething", "someparameter": 52})
+```

+- [(Mapping[str, ValueTypes])](https://docs.python.org/3/library/stdtypes.html#typesmapping): Result of the executed command.

 ## Control Tab Usage
 
 After configuring the navigation service for your robot, navigate to the **Control** tab of the robot's page in the [Viam app](https://app.viam.com) and expand the card matching the name of your service to use an interface for rover navigation.
