Detailed Description

ImitateCtrl copies the trajectory's velocities.

As velocities are directly copied, any error in the beginning will gets bigger and bigger.

Since: 0.3.1

Constructor & Destructor Documentation

ImitateCtrl::ImitateCtrl	(	const MotionModel &	model,
		const double &	ts,
		const char *	input_file_name,
		const iSeeML::rob::OrPtConfig &	init_config
	)

inline

The constructor needs a motion model, a file name giving the path to track and an initial configuration.

States from the path are projected into the initial configuration's frame.

Parameters

model	the motion model,
ts	the time step of the controller,
input_file_name	the input file name of the path,
init_config	the initial configuration.

virtual ImitateCtrl::~ImitateCtrl ( )

inlinevirtual

The destructor needs to be explicitely redefined.

Member Function Documentation

void ImitateCtrl::chooseVelocities	(	double &	trans_vel,
		double &	rot_vel,
		std::ostream &	log_str
	)

virtual

Computes new velocities for ROS node.

This method has to be defined by inheritors. It should use updateVelocities.

Parameters

trans_vel	the translation velocity, sent by the ROS node to ROS,
rot_vel	the rotation velocity, sent to ROS,
log_str	the log stream, allowing to log debug data.

Reimplemented from FileCtrl.
