Send/Receive arbitrary commands to the Resource


command (Mapping[str, ValueTypes]) – The command to execute


NotImplementedError – Raised if the Resource does not support arbitrary commands


Result of the executed command

Return type:

Mapping[str, ValueTypes]

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

Get the service named name from the provided robot.

  • robot (RobotClient) – The robot

  • name (str) – The name of the service


The service, if it exists on the robot

Return type:


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

Get the ResourceName for this Resource with the given name


name (str) – The name of the Resource

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. ).


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


The operation associated with this function

Return type:


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 retun errors when future non-Close methods are called.
