Detailed Description

This is identical to the STaskOpPos for now

Constructor & Destructor Documentation

scl::STaskOpPosNoGravity::STaskOpPosNoGravity ( )

inline

Default constructor sets stuff to S_NULL

virtual scl::STaskOpPosNoGravity::~STaskOpPosNoGravity ( )

Initialization function

NOTE : This function also activates the task.

Parameters

arg_task_dof	0 task dof means a gc task. Ie. full dofs
arg_nonstd_params	These are ignored during STaskBase initialization. However, subclasses may choose to use them and/or require various values

bool scl::STaskOpPos::initTaskParams ( )

virtualinherited

Initializes the task specific data members.

Parses non standard task parameters, which are stored in STaskBase::task_nonstd_params_. Namely: (a) parent link name (b) pos in parent.

Extract the extra params

Implements scl::STaskBase.

bool scl::STaskBase::setParentController ( const SControllerMultiTask * arg_parent )

inherited

Sets the parent controller

Member Data Documentation

scl::sUInt scl::STaskBase::dof_task_

inherited

Task space degrees of freedom

Eigen::VectorXd scl::STaskBase::force_gc_

inherited

Generalized coordinate forces (usually joint torques) : Computed by : the task-servo = J' * f Used by : the robot-servo to calculate overall generalized coordinate force

Eigen::VectorXd scl::STaskBase::force_task_

inherited

Task space forces Computed by : the task-servo Used by : the task-servo to compute the force_gc_

Eigen::MatrixXd scl::STaskBase::force_task_cc_

inherited

Task-space centrifugal/coriolis force vector Controls cc forces in a subspace of the entire gc space so that the operational point experience no cc forces. Other points, however, do.

Eigen::MatrixXd scl::STaskBase::force_task_grav_

inherited

Task-space gravity force vector. Controls gravity in a subspace of the entire gc space so that the operational point is massless. Other points experience gravity.

Eigen::VectorXd scl::STaskBase::force_task_max_

inherited

Upper and lower limits of task-space forces (Why separate : Consider muscles which can only pull, not push)

const SGcModel* scl::STaskBase::gc_model_

inherited

Robot generalized coordinate model

scl::sBool scl::STaskBase::has_been_activated_

inherited

Whether the task is active or inactive Default = false. True after init()

sBool scl::SObject::has_been_init_

inherited

Whether the object is ready for use

scl::sBool scl::STaskBase::has_control_null_space_

inherited

Is control task. This variable controls whether the controller computes remaining null spaces for lower level tasks or not. If it is true, the lower level task null spaces are not computed, potentially improving performance substantially.

Settings: True : Task dof < Robot dof [Default] False : Task dof == Robot dof [Must enable manually in init]

Eigen::MatrixXd scl::STaskBase::J_

inherited

The computed task space Jacobian matrices. Used for velocities. Note that we compute the generalized inverse (the Jacobian is usually not full rank) without inverting the jacobian itself.

Eigen::VectorXd scl::STaskBase::kp_

inherited

Gains (scalar if same for different dimensions; vector if different for different dimensions) kp = position, kv = velocity, ka = acceleration ki = integrated position error (to fix steady-state errors).

Computed by : None. These are constants. Used by : The task-servo to calculate task forces

Eigen::MatrixXd scl::STaskBase::M_task_

inherited

Task-space mass matrix

std::string scl::SObject::name_

inherited

The object's name

Eigen::MatrixXd scl::STaskBase::null_space_

inherited

The task's null space. Used to compute the range space of lower priority tasks.

const SControllerMultiTask* scl::STaskBase::parent_controller_

inherited

The parent controller

sUInt scl::STaskBase::priority_

inherited

The task's priority. Important to determine its range space. Lower is better. 0 is best. -1 is NULL.

Eigen::MatrixXd scl::STaskBase::range_space_

inherited

Range space of the task : Computed by : the robot-servo to calculate overall generalized coordinate force Used by : the robot-servo to calculate overall generalized coordinate force

const SRobotParsed* scl::STaskBase::robot_

inherited

Robot model. Not a const because it could use the branching representation's iterator

Eigen::VectorXd scl::STaskBase::shared_data_

inherited

This may be used by any shared module in scl that wants to communicate arbitrary information to a STaskBase subclass

std::vector<sString2> scl::STaskBase::task_nonstd_params_

inherited

A set of additional options that may be used by users to initialize this specific task. These typically go above and beyond the standard options.

Eg.The parent link and the pos in parent, which are required by op point tasks but not by gc tasks. These will be stored like: task_options_[0].data_[0] = "parent_link"; task_options_[0].data_[1] = "base"; task_options_[1].data_[0] = "pos_in_parent"; task_options_[1].data_[1] = "0.0 0.0 0.0"; task_options_[2].data_[0] = "my_new_arbitrary_option"; task_options_[2].data_[1] = "8080";

std::string scl::SObject::type_

protectedinherited

The object's type. Should only be set by the constructor

std::string scl::STaskBase::type_task_

inherited

The type of the task
