◆ readPosFile()

bool vpRobotUniversalRobots::readPosFile	(	const std::string &	filename,

Read joint positions in a specific Franka position file.

This position file has to start with a header. The seven joint positions are given after the "R:" keyword and are expressed in degres to be more representative for the user. Theses values are then converted in radians in q. The character "#" starting a line indicates a comment.

A typical content of such a file is given below:

#UR - Joint position file
#
# R: q1 q2 q3 q4 q5 q6
# with joint positions q1 to q6 expressed in degrees
#
R: 0.1 0.3 -0.25 -80.5 80 0

Parameters

[in]	filename	: Name of the position file to read.
[out]	q	: 6-dim joint positions: q1 q2 q3 q4 q5 q6 with values expressed in radians.

Returns: true if the positions were successfully read from the file, false otherwise.

The code below shows how to read a position from a file and move the robot to this position.

vpRobotUniversalRobots robot;
vpColVector q;        // Joint position
robot.readPosFile("myposition.pos", q); // Set the joint position from the file
robot.setRobotState(vpRobot::STATE_POSITION_CONTROL);
 
robot.setPositioningVelocity(5); // Positioning velocity set to 5%
robot.setPosition(vpRobot::JOINT_STATE, q); // Move to the joint position

[in]	frame	: Control frame in which the velocity is expressed. Velocities could be expressed in joint state, robot base frame, end-effector frame or camera frame.
[in]	vel	: Velocity vector. Translation velocities are expressed in m/s while rotation velocities in rad/s. The size of this vector is always 6.

In joint state, $vel = [\dot{q}_1, \dot{q}_2, \dot{q}_3, \dot{q}_4, \dot{q}_5, \dot{q}_6]^t$ correspond to joint velocities in rad/s.
When cartesian velocities have to be applied in the reference frame corresponding to the robot base frame, frame should be set to vpRobot::REFERENCE_FRAME, $vel = [^{f} v_x, ^{f} v_y, ^{f} v_z, ^{f} \omega_x, ^{f} \omega_y, ^{f} \omega_z]^T$ is a velocity twist vector corresponding to the velocity of the origin of the end-effector frame expressed in the reference frame, with translations velocities $^{f} v_x, ^{f} v_y, ^{f} v_z$ in m/s and rotation velocities $^{f}\omega_x, ^{f} \omega_y, ^{f} \omega_z$ in rad/s.
When cartesian velocities have to be applied in the end-effector frame, frame should be set to vpRobot::END_EFFECTOR_FRAME, $vel = [^{e} v_x, ^{e} v_y, ^{e} v_z, ^{e} \omega_x, ^{e} \omega_y, ^{e} \omega_z]^T$ is a velocity twist vector corresponding to the velocity of the origin of the end-effector frame expressed in the end-effector frame, with translations velocities $^{e} v_x, ^{e} v_y, ^{e} v_z$ in m/s and rotation velocities $^{e}\omega_x, ^{e} \omega_y, ^{e} \omega_z$ in rad/s.
When cartesian velocities have to be applied in the camera frame or more generally in a tool frame, frame should be set to vpRobot::CAMERA_FRAME or vpRobot::TOOL_FRAME (which are equivalent in ViSP), $vel = [^{c} v_x, ^{c} v_y, ^{c} v_z, ^{c} \omega_x, ^{c} \omega_y, ^{c} \omega_z]^T$ is a velocity twist vector corresponding to the velocity of the origin of the camera (or tool frame) frame expressed in the camera (or tool frame), with translations velocities $^{c} v_x, ^{c} v_y, ^{c} v_z$ in m/s and rotation velocities $^{c}\omega_x, ^{c} \omega_y, ^{c} \omega_z$ in rad/s. The position of the camera frame could be set using set_eMc().

Exceptions

vpRobotException::wrongStateError : If a the robot is not configured to handle a velocity. The robot can handle a velocity only if the velocity control mode is set. For that, call setRobotState( vpRobot::STATE_VELOCITY_CONTROL) before setVelocity().

Warning: Velocities could be saturated if one of them exceed the maximal authorized speed (see vpRobot::maxTranslationVelocity and vpRobot::maxRotationVelocity). To change these values use setMaxTranslationVelocity() and setMaxRotationVelocity().
