Motion service API
The motion service exposes the methods below for planning and executing component motion. Most methods are implemented only by module-based motion services; the builtin service supports Move, DoCommand, and GetStatus.
| Method Name | Description |
|---|---|
Move | The Move method is the primary way to move multiple components, or to move any object to any other location. |
MoveOnMap | Move a base component to a destination pose on a SLAM map. |
MoveOnGlobe | Move a base component to a destination GPS point, represented in geographic notation (latitude, longitude). |
GetPose | GetPose gets the location and orientation of a component within the frame system. |
StopPlan | Stop a base component being moved by an in progress MoveOnGlobe or MoveOnMap call. |
ListPlanStatuses | Returns the statuses of plans created by MoveOnGlobe or MoveOnMap calls that meet at least one of the following conditions since the motion service initialized: - the plan’s status is in progress - the plan’s status changed state within the last 24 hours All repeated fields are in chronological order. |
GetPlan | By default, returns the plan history of the most recent MoveOnGlobe or MoveOnMap call to move a base component. |
Reconfigure | Reconfigure this resource. |
FromRobot | Get the resource from the provided machine. |
DoCommand | Execute model-specific commands that are not otherwise defined by the service API. |
GetResourceName | Get the ResourceName for this instance of the motion service. |
Close | Safely shut down the resource and prevent further use. |
For full method signatures, parameters, and code examples, see the auto-generated motion API reference.
Method overview
Move
Plans and executes a motion to a destination pose. This is the primary method for arm and gantry planning.
Key parameters:
component_name: the arm or gantry to movedestination: aPoseInFramespecifying the target pose and reference frameworld_state: optional obstacles and transformsconstraints: optional linear, orientation, or collision constraints
MoveOnMap
Plans and executes motion on a SLAM map.
MoveOnGlobe
Plans and executes motion to a GPS coordinate. Use the navigation service for GPS-based navigation.
GetPlan
Retrieves the plan for an executing motion.
ListPlanStatuses
Lists all active and recently completed plan statuses.
StopPlan
Stops an executing plan.
GetPose (deprecated)
Returns a component’s pose. Deprecated: the robot service’s GetPose replaces it. (Python callers currently still use this motion-service method; see the frame system API reference.)
DoCommand
Sends arbitrary commands. The builtin motion service supports "plan",
"execute", and "executeCheckStart" commands.
GetStatus
Returns generic resource status for the motion service. Useful for liveness checks.
