async do_command(command: Mapping[str, viam.utils.ValueTypes], *, timeout: float | None = None, **__) Mapping[str, viam.utils.ValueTypes][source]

Send/Receive arbitrary commands to the Resource

command = {"cmd": "test", "data1": 500}

Return type:

Mapping[str, ValueTypes]

async get_geometries(*, extra: Dict[str, Any] | None = None, timeout: float | None = None) List[viam.proto.common.Geometry][source]

Get all geometries associated with the component, in their current configuration, in the frame of the component.

geometries = await component.get_geometries()

if geometries:
    # Get the center of the first geometry
    print(f"Pose of the first geometry's centerpoint: {geometries[0].center}")
Returns:

classmethod from_robot(robot: viam.robot.client.RobotClient, name: str) typing_extensions.Self

Get the component named name from the provided robot.

Parameters:
  • robot (RobotClient) – The robot

  • name (str) – The name of the component

Returns:

The component, if it exists on the robot

Return type:

Self

classmethod get_resource_name(name: str) viam.proto.common.ResourceName

Get the ResourceName for this Resource with the given name

# Can be used with any resource, using an arm as an example
my_arm_name = my_arm.get_resource_name("my_arm")
Parameters:

name (str) – The name of the Resource

Returns:

The ResourceName of this Resource

Return type:

ResourceName

get_operation(kwargs: Mapping[str, Any]) viam.operations.Operation

Get the Operation associated with the currently running function.

When writing custom resources, you should get the Operation by calling this function and check to see if it’s cancelled. If the Operation is cancelled, then you can perform any necessary (terminating long running tasks, cleaning up connections, etc. ).

Parameters:

kwargs (Mapping[str, Any]) – The kwargs object containing the operation

Returns:

The operation associated with this function

Return type:

viam.operations.Operation

async close()

Safely shut down the resource and prevent further use.

Close must be idempotent. Later configuration may allow a resource to be “open” again. If a resource does not want or need a close function, it is assumed that the resource does not need to return errors when future non-Close methods are called.

await component.close()
