Detailed Description

Simulator of Irisa's Viper S850 robot named Viper850.

Implementation of the vpRobotWireFrameSimulator class in order to simulate Irisa's Viper850 robot. This robot is an ADEPT six degrees of freedom arm.

Warning
This class uses threading capabilities. Thus on Unix-like platforms, the libpthread third-party library need to be installed. On Windows, we use the native threading capabilities.

This class allows to control the Viper850 arm robot in position and velocity:

End-effector frame (vpRobot::END_EFFECTOR_FRAME) is not implemented.

All the translations are expressed in meters for positions and m/s for the velocities. Rotations are expressed in radians for the positions, and rad/s for the rotation velocities.

The direct and inverse kinematics models are implemented in the vpViper850 class.

To control the robot in position, you may set the controller to position control and then send the position to reach in a specific frame like here in the joint space:

#include <visp3/core/vpColVector.h>
#include <visp3/core/vpConfig.h>
#include <visp3/core/vpMath.h>
#include <visp3/robot/vpSimulatorViper850.h>
int main()
{
// Set a joint position
q[0] = vpMath::rad(10); // Joint 1 position, in rad
q[1] = 0.2; // Joint 2 position, in rad
q[2] = 0.3; // Joint 3 position, in rad
q[3] = M_PI/8; // Joint 4 position, in rad
q[4] = M_PI/4; // Joint 5 position, in rad
q[5] = M_PI; // Joint 6 position, in rad
// Initialize the controller to position control
// Moves the robot in the joint space
return 0;
}

The robot moves to the specified position with the default positioning velocity vpRobotViper850::defaultPositioningVelocity. The setPositioningVelocity() method allows to change the maximal velocity used to reach the desired position.

#include <visp3/core/vpColVector.h>
#include <visp3/core/vpMath.h>
#include <visp3/robot/vpSimulatorViper850.h>
int main()
{
// Set q[i] with i in [0:5]
// Initialize the controller to position control
// Set the max velocity to 40%
// Moves the robot in the joint space
return 0;
}

To control the robot in velocity, you may set the controller to velocity control and then send the velocities. To end the velocity control and stop the robot you have to set the controller to the stop state. Here is an example of a velocity control in the joint space:

#include <visp3/core/vpColVector.h>
#include <visp3/core/vpMath.h>
#include <visp3/robot/vpSimulatorViper850.h>
int main()
{
vpColVector qvel(6);
// Set a joint velocity
qvel[0] = 0.1; // Joint 1 velocity in rad/s
qvel[1] = vpMath::rad(15); // Joint 2 velocity in rad/s
qvel[2] = 0; // Joint 3 velocity in rad/s
qvel[3] = M_PI/8; // Joint 4 velocity in rad/s
qvel[4] = 0; // Joint 5 velocity in rad/s
qvel[5] = 0; // Joint 6 velocity in rad/s
// Initialize the controller to position control
for ( ; ; ) {
// Apply a velocity in the joint space
// Compute new velocities qvel...
}
// Stop the robot
return 0;
}

It is also possible to measure the robot current position with getPosition() method and the robot current velocities with the getVelocity() method.

For convenience, there is also the ability to read/write joint positions from a position file with readPosFile() and savePosFile() methods.

To know how this class can be used to achieve a visual servoing simulation, you can follow the Tutorial: Image-based visual servo.

Examples:
servoSimuViper850FourPoints2DCamVelocity.cpp, and tutorial-ibvs-4pts-wireframe-robot-viper.cpp.

Member Function Documentation

◆ compute_fMi()

void vpSimulatorViper850::compute_fMi ( )
protected

Compute the pose between the robot reference frame and the frames used to compute the Denavit-Hartenberg representation. The last element of the table corresponds to the pose between the reference frame and the camera frame.

To compute the different homogeneous matrices, this function needs the articular coordinates as input.

Finally the output is a table of 8 elements : $ fM1 $, $ fM2 $, $ fM3 $, $ fM4 $, $ fM5 $, $ fM6 = fMw $, $ fM7 = fMe $ and $ fMc $ - where w is for wrist and e for effector-.

Warning
This method needs XML library to parse the file defined in vpViper850::CONST_CAMERA_FILENAME and containing the camera parameters. If XML is detected by ViSP, VISP_HAVE_PUGIXML macro is defined in include/visp3/core/vpConfig.h file.
Thid method needs also an access to the files containing the camera parameters in XML format. This access is available if VISP_HAVE_VIPER850_DATA macro is defined in include/visp3/core/vpConfig.h file.
  • If VISP_HAVE_VIPER850_DATA and VISP_HAVE_PUGIXML macros are defined, this method gets the camera parameters from const_camera_Viper850.xml config file.

◆ readPosFile()

bool vpSimulatorViper850::readPosFile ( const std::string &  filename,
vpColVector q 
)
static

Read joint positions in a specific Viper850 position file.

This position file has to start with a header. The six joint positions are given after the "R:" keyword. The first 3 values correspond to the joint translations X,Y,Z expressed in meters. The 3 last values correspond to the joint rotations A,B,C 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:

#Viper - Position - Version 1.0
# file: "myposition.pos "
#
# R: A B C D E F
# Joint position in degrees
#
R: 0.1 0.3 -0.25 -80.5 80 0
Parameters
filename: Name of the position file to read.
q: The six joint positions. Values are expressed in radians.
Returns
true if the positions were successfully readen in the file. false, if an error occurs.

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

#include <visp3/core/vpColVector.h>
#include <visp3/robot/vpSimulatorViper850.h>
int main()
{
// Enable the position control of the robot
// Get the current robot joint positions
vpColVector q; // Current joint position
// Save this position in a file named "current.pos"
robot.savePosFile("current.pos", q);
// Get the position from a file and move to the registered position
robot.readPosFile("current.pos", q); // Set the joint position from the file
robot.setPositioningVelocity(5); // Positioning velocity set to 5%
robot.setPosition(vpRobot::ARTICULAR_FRAME, q); // Move to the joint position
}

const vpColVector v_max,
bool  verbose = false 
)
staticinherited

Saturate velocities.

Parameters
v_in: Vector of input velocities to saturate. Translation velocities should be expressed in m/s while rotation velocities in rad/s.
v_max: Vector of maximal allowed velocities. Maximal translation velocities should be expressed in m/s while maximal rotation velocities in rad/s.
verbose: Print a message indicating which axis causes the saturation.
Returns

v[5] = vpMath::rad(20); // wz
// Set the maximal allowed velocities
vpColVector v_max(6);
for (int i=0; i<3; i++)
v_max[i] = 0.3; // in translation (m/s)
for (int i=3; i<6; i++)
v_max[i] = vpMath::rad(10); // in rotation (rad/s)
// Compute the saturated velocity skew vector
vpColVector v_sat = vpRobot::saturateVelocities(v, v_max, true);
std::cout << "v : " << v.t() << std::endl;

Warning
This method is blocking. It returns only when the position is reached by the robot.
Parameters
q: A six dimension vector corresponding to the position to reach. All the positions are expressed in meters for the translations and radians for the rotations. If the position is out of range, an exception is provided.
frame: Frame in which the position is expressed.
  • In the joint space, positions are respectively X, Y, Z, A, B, C, with X,Y,Z the translations, and A,B,C the rotations of the end-effector.
  • In the camera and the reference frame, rotations are represented by a vpRxyzVector.
  • Mixt frame is not implemented. By mixt frame we mean, translations expressed in the reference frame, and rotations in the camera frame.
Exceptions
vpRobotException::lowLevelError: vpRobot::MIXT_FRAME not implemented.
vpRobotException::positionOutOfRangeError: The requested position is out of range.
#include <visp3/core/vpColVector.h>
#include <visp3/robot/vpSimulatorViper850.h>

  • In articular, $ 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.
  • In camera frame, $ 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 expressed in the camera 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.
  • In reference frame, $ vel = [^{r} v_x, ^{r} v_y, ^{r} v_z, ^{r} \omega_x, ^{r} \omega_y, ^{r} \omega_z]^t $ is a velocity twist vector expressed in the reference 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.
  • In mixt frame, $ vel = [^{r} v_x, ^{r} v_y, ^{r} v_z, ^{c} \omega_x, ^{c} \omega_y, ^{c} \omega_z]^t $ is a velocity twist vector where, translations $ ^{r} v_x, ^{r} v_y, ^{r} v_z $ are expressed in the reference frame in m/s and rotations $ ^{c} \omega_x, ^{c} \omega_y, ^{c} \omega_z $ in the camera frame in rad/s.
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
