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:

in the joint space (vpRobot::ARTICULAR_FRAME),
in the fixed reference frame (vpRobot::REFERENCE_FRAME),
in the camera frame (vpRobot::CAMERA_FRAME),
or in a mixed frame (vpRobot::MIXT_FRAME) where translations are expressed in the reference frame and rotations in the camera frame.

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()
{
  vpSimulatorViper850 robot;
  vpColVector q(6);
  // 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
  robot.setRobotState(vpRobot::STATE_POSITION_CONTROL);
  // Moves the robot in the joint space
  robot.setPosition(vpRobot::ARTICULAR_FRAME, q);
  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()
{
  vpSimulatorViper850 robot;
  vpColVector q(6);
  // Set q[i] with i in [0:5]
  // Initialize the controller to position control
  robot.setRobotState(vpRobot::STATE_POSITION_CONTROL);
  // Set the max velocity to 40%
  robot.setPositioningVelocity(40);
  // Moves the robot in the joint space
  robot.setPosition(vpRobot::ARTICULAR_FRAME, q);
  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()
{
  vpSimulatorViper850 robot;
  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
  robot.setRobotState(vpRobot::STATE_VELOCITY_CONTROL);
  for ( ; ; ) {
    // Apply a velocity in the joint space
    robot.setVelocity(vpRobot::ARTICULAR_FRAME, qvel);
    // Compute new velocities qvel...
  }
  // Stop the robot
  robot.setRobotState(vpRobot::STATE_STOP);
  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.

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-.

◆ 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()
{
  vpSimulatorViper850 robot;
  // Enable the position control of the robot
  robot.setRobotState(vpRobot::STATE_POSITION_CONTROL);
  // Get the current robot joint positions
  vpColVector q;        // Current joint position
  robot.getPosition(vpRobot::ARTICULAR_FRAME, q);
  // 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
}

  v[3] = vpMath::rad(10);   // wx in rad/s
  v[4] = vpMath::rad(-10);  // wy
  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);

Move to an absolute position with a given percent of max velocity. The percent of max velocity is to set with setPositioningVelocity(). The position to reach can be specified in joint coordinates, in the camera frame or in the reference frame.

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>
int main()

  // Set the max velocity to 20%
  robot.setPositioningVelocity(20);
  // Moves the robot in the camera frame
  robot.setPosition(vpRobot::CAMERA_FRAME, position);
}

To catch the exception if the position is out of range, modify the code like:

try {
  robot.setPosition(vpRobot::CAMERA_FRAME, position);
}
catch (vpRobotException &e) {
  if (e.getCode() == vpRobotException::positionOutOfRangeError) {
  std::cout << "The position is out of range" << std::endl;

◆ setPosition() [3/3]

void vpSimulatorViper850::setPosition ( const char * filename )

Move to an absolute joint position with a given percent of max velocity. The robot state is set to position control. The percent of max velocity is to set with setPositioningVelocity(). The position to reach is defined in the position file.

Parameters

filename : Name of the position file to read. The readPosFile() documentation shows a typical content of such a position file.

This method has the same behavior than the sample code given below;

#include <visp3/core/vpColVector.h>
#include <visp3/robot/vpSimulatorViper850.h>
int main()
{
  vpColVector q;
  vpSimulatorViper850 robot;
  robot.readPosFile("MyPositionFilename.pos", q);
  robot.setRobotState(vpRobot::STATE_POSITION_CONTROL);
  robot.setPosition(vpRobot::ARTICULAR_FRAME, q);
}

Exceptions

vpRobotException::lowLevelError	: vpRobot::MIXT_FRAME not implemented.
vpRobotException::positionOutOfRangeError	: The requested position is out of range.

◆ setVelocity()

void vpSimulatorViper850::setVelocity	(	const vpRobot::vpControlFrameType	frame,
		const vpColVector &	vel
	)

virtual

Apply a velocity to the robot.

Parameters

frame	: Control frame in which the velocity is expressed. Velocities could be expressed in articular, camera frame, reference frame or mixt frame.
vel	: Velocity vector. The size of this vector is always 6.

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