Detailed Description

Representation of a robot's state. This includes position, velocity, acceleration and effort.

At the lowest level, a state is a collection of variables. Each variable has a name and can have position, velocity, acceleration and effort associated to it. Effort and acceleration share the memory area for efficiency reasons (one should not set both acceleration and effort in the same state and expect things to work). Often variables correspond to joint names as well (joints with one degree of freedom have one variable), but joints with multiple degrees of freedom have more variables. Operations are allowed at variable level, joint level (see JointModel) and joint group level (see JointModelGroup).

For efficiency reasons a state computes forward kinematics in a lazy fashion. This can sometimes lead to problems if the update() function was not called on the state.

void moveit::core::RobotState::allocMemory ( void  ) [private]

Definition at line 78 of file robot_state.cpp.

Add an attached body to this state. Ownership of the memory for the attached body is assumed by the state.

This only adds the given body to this RobotState instance. It does not change anything about other representations of the object elsewhere in the system. So if the body represents an object in a collision_detection::World (like from a planning_scene::PlanningScene), you will likely need to remove the corresponding object from that world to avoid having collisions detected against it.

Note:
This version of the function (taking an AttachedBody pointer) does not copy the AttachedBody object, it just uses it directly. The AttachedBody object stores its position data internally. This means you should never attach a single AttachedBody instance to multiple RobotState instances, or the body positions will get corrupted. You need to make a fresh copy of the AttachedBody object for each RobotState you attach it to.

Definition at line 839 of file robot_state.cpp.

const std::string &  link_name,
const trajectory_msgs::JointTrajectory &  detach_posture = trajectory_msgs::JointTrajectory() 
)

Add an attached body to a link.

Parameters:
idThe string id associated with the attached body
shapesThe shapes that make up the attached body
attach_transThe desired transform between this link and the attached body
touch_linksThe set of links that the attached body is allowed to touch
link_nameThe link to attach to

This only adds the given body to this RobotState instance. It does not change anything about other representations of the object elsewhere in the system.

double  distance,
double  max_step,

const GroupStateValidityCallbackFn validCallback = GroupStateValidityCallbackFn(),
const kinematics::KinematicsQueryOptions options = kinematics::KinematicsQueryOptions() 
)

Compute the sequence of joint values that correspond to a straight Cartesian path for a particular group.

The Cartesian path to be followed is specified as a direction of motion (direction, unit vector) for the origin of a robot link (link). The direction is assumed to be either in a global reference frame or in the local reference frame of the link. In the latter case (global_reference_frame is false) the direction is rotated accordingly. The link needs to move in a straight line, following the specified direction, for the desired distance. The resulting joint values are stored in the vector traj, one by one. The maximum distance in Cartesian space between consecutive points on the resulting path is specified by max_step. If a validCallback is specified, this is passed to the internal call to setFromIK(). In case of IK failure, the computation of the path stops and the value returned corresponds to the distance that was computed and for which corresponding states were added to the path. At the end of the function call, the state of the group corresponds to the last attempted Cartesian pose. During the computation of the trajectory, it is sometimes preferred if consecutive joint values do not 'jump' by a large amount in joint space, even if the Cartesian distance between the corresponding points is as expected. To account for this, the jump_threshold parameter is provided. As the joint values corresponding to the Cartesian path are computed, distances in joint space between consecutive points are also computed. Once the sequence of joint values is computed, the average distance between consecutive points (in joint space) is also computed. It is then verified that none of the computed distances is above the average distance by a factor larger than jump_threshold. If a point in joint is found such that it is further away than the previous one by more than average_consecutive_distance * jump_threshold, that is considered a failure and the returned path is truncated up to just before the jump. The jump detection can be disabled by setting jump_threshold to 0.0

Compute the sequence of joint values that correspond to a straight Cartesian path, for a particular group.

The Cartesian path to be followed is specified as a target frame to be reached (target) for the origin of a robot link (link). The target frame is assumed to be either in a global reference frame or in the local reference frame of the link. In the latter case (global_reference_frame is false) the target is rotated accordingly. The link needs to move in a straight line towards the target. The resulting joint values are stored in the vector traj, one by one. The maximum distance in Cartesian space between consecutive points on the resulting path is specified by max_step. If a validCallback is specified, this is passed to the internal call to setFromIK(). In case of IK failure, the computation of the path stops and the value returned corresponds to the percentage of the path (between 0 and 1) that was completed and for which corresponding states were added to the path.

Compute the sequence of joint values that perform a general Cartesian path.

The Cartesian path to be followed is specified as a set of waypoints to be sequentially reached for the origin of a robot link (link). The waypoints are transforms given either in a global reference frame or in the local reference frame of the link at the immediately preceeding waypoint. The link needs to move in a straight line between two consecutive waypoints. The resulting joint values are stored in the vector traj, one by one. The maximum distance in Cartesian space between consecutive points on the resulting path is specified by max_step. If a validCallback is specified, this is passed to the internal call to setFromIK(). In case of IK failure, the computation of the path stops and the value returned corresponds to the percentage of the path (between 0 and 1) that was completed and for which corresponding states were added to the path.

For certain operations a state needs a random number generator. However, it may be slightly expensive to allocate the random number generator if many state instances are generated. For this reason, the generator is allocated on a need basis, by the getRandomNumberGenerator() function. Never use the rng_ member directly, but call getRandomNumberGenerator() instead.
