GantryClient

gRPC client for the Gantry component.
class viam.components.gantry.client.GantryClient(name: str, channel: grpclib.client.Channel)[source]

Bases: viam.components.gantry.gantry.Gantry, viam.resource.rpc_client_base.ReconfigurableResourceRPCClientBase

gRPC client for the Gantry component.

async get_position(*, extra: Optional[Dict[str, Any]] = None, timeout: Optional[float] = None) → List[float][source]

Get the position in millimeters.

Returns:

The position of the axes.

Return type:

List[float]

async move_to_position(positions: List[float], speeds: List[float], *, extra: Optional[Dict[str, Any]] = None, timeout: Optional[float] = None)[source]

Move the gantry to a new position at the requested speeds.

Parameters:

positions (List[float]) – List of positions for the axes to move to, in millimeters.

async home(*, extra: Optional[Dict[str, Any]] = None, timeout: Optional[float] = None) → bool[source]

Home the gantry to find it’s starting and ending positions

Returns:

whether the gantry has run the homing sequence successfully

Return type:

bool

async get_lengths(*, extra: Optional[Dict[str, Any]] = None, timeout: Optional[float] = None) → List[float][source]

Get the lengths of the axes of the gantry in millimeters.

Returns:

The lengths of the axes.

Return type:

List[float]

async stop(*, extra: Optional[Dict[str, Any]] = None, timeout: Optional[float] = None)[source]

Stop all motion of the gantry. It is assumed that the gantry stops immediately.

async is_moving(*, timeout: Optional[float] = None) → bool[source]

Get if the gantry is currently moving.

Returns:

Whether the gantry is moving.

Return type:

bool

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

Send/Receive arbitrary commands to the Resource

Parameters:

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

Raises:

NotImplementedError – Raised if the Resource does not support arbitrary commands

Returns:

Result of the executed command

Return type:

Mapping[str, ValueTypes]

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

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

Returns:

The geometries associated with the Component.

Return type:

List[Geometry]

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

Parameters:

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. ).

Parameters:

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

Returns:

The operation associated with this function

Return type:

viam.operations.Operation
