Type

float

property planner_id

The planner id to use.

Type

str

property planning_attempts

The number of planning attempts to make.

Type

int

property planning_pipeline

The planning pipeline to use.

Type

str

property planning_time

Type

float

class moveit.planning.PlanningComponent

Represents a joint model group and motion plans corresponding to this joint model group.

get_named_target_state_values()

dict: The joint values for targets specified by name.

get_start_state()

Returns the current start state for the planning component.

property named_target_states

The names of the named robot states available as targets.

Type

list of str

plan()

Plan a motion plan using the current start and goal states.

Parameters

plan_parameters (moveit_py.core.PlanParameters) – The parameters to use for planning.

property planning_group_name

The name of the planning group to plan for.

Type

str

set_goal_state()

Set the goal state for the planning component.

Parameters

• configuration_name (str) – The name of the configuration to set the goal to.

• robot_state (moveit_py.core.RobotState) – The state to set the goal to.

• pose_stamped_msg (geometry_msgs.msg.PoseStamped) – A PoseStamped ros message.

• pose_link (str) – The name of the link for which the pose constraint is specified.

• motion_plan_constraints (list) – The motion plan constraints to set the goal to.

set_path_constraints()

Set the path constraints generated from a moveit msg Constraints.

Parameters

path_constraints (moveit_msgs.msg.Constraints) – The path constraints.

set_start_state()

Set the start state of the plan to the given robot state.

Parameters

• configuration_name (str) – The name of the configuration to use as the start state.

• robot_state (moveit_msgs.msg.RobotState) – The robot state to use as the start state.

set_start_state_to_current_state()

Set the start state of the plan to the current state of the robot.

set_workspace()

Specify the workspace bounding box. The box is specified in the planning frame (i.e. relative to the robot root link start position). The workspace applies only to the root joint of a mobile robot (driving base, quadrotor) and does not limit the workspace of a robot arm.

Parameters

• min_x (float) – The minimum x value of the workspace.

• min_y (float) – The minimum y value of the workspace.

• min_z (float) – The minimum z value of the workspace.

• max_x (float) – The maximum x value of the workspace.

• max_y (float) – The maximum y value of the workspace.

• max_z (float) – The maximum z value of the workspace.

unset_workspace()

Remove the workspace bounding box from planning.

class moveit.planning.PlanningSceneMonitor

Maintains the internal state of the planning scene.

clear_octomap()

read_write()

Returns a read-write context manager for the planning scene.

start_scene_monitor()

Starts the scene monitor.

start_state_monitor()

Starts the state monitor.

stop_scene_monitor()

Stops the scene monitor.

stop_state_monitor()
