MoveItPlanner.plan_motion
- MoveItPlanner.plan_motion(robot, target, start_configuration=None, group=None, options=None)[source]
Calculates a motion path.
- Parameters:
- robot
compas_fab.robots.Robot
The robot instance for which the motion plan is being calculated.
- target: list of :class:`compas_fab.robots.Target`
The target for the robot to reach.
- start_configuration: :class:`compas_fab.robots.Configuration`, optional
The robot’s full configuration, i.e. values for all configurable joints of the entire robot, at the starting position. Defaults to the all-zero configuration.
- group: str, optional
The name of the group to plan for. Defaults to the robot’s main planning group.
- optionsdict, optional
Dictionary containing the following key-value pairs:
"base_link"
: (str
) Name of the base link."path_constraints"
: (list
ofcompas_fab.robots.Constraint
, optional) Optional constraints that can be imposed along the solution path. Note that path calculation won’t work if the start_configuration violates these constraints. Defaults toNone
."planner_id"
: (str
) The name of the algorithm used for path planning. Defaults to'RRTConnect'
."num_planning_attempts"
: (int
, optional) Normally, if one motion plan is needed, one motion plan is computed. However, for algorithms that use randomization in their execution (like ‘RRT’), it is likely that different planner executions will produce different solutions. Setting this parameter to a value above1
will run many additional motion plans, and will report the shortest solution as the final result. Defaults to1
.'allowed_planning_time'
: (float
) The number of seconds allowed to perform the planning. Defaults to2
."max_velocity_scaling_factor"
: (float
) Defaults to1
."max_acceleration_scaling_factor"
: (float
) Defaults to1
."attached_collision_meshes"
: (list
ofcompas_fab.robots.AttachedCollisionMesh
) Defaults toNone
.
- robot
- Returns:
compas_fab.robots.JointTrajectory
The calculated trajectory.
