Detailed Description

Control of Irisa's Viper S650 robot named Viper650.

Implementation of the vpRobot class in order to control Irisa's Viper650 robot. This robot is an ADEPT six degrees of freedom arm. A firewire camera is mounted on the end-effector to allow eye-in-hand visual servoing. The control of this camera is achieved by the vp1394TwoGrabber class.

The model of the robot is the following:

Model of the Viper 650 robot.

The non modified Denavit-Hartenberg representation of the robot is given in the table below, where $q_1^*, \ldots, q_6^*$ are the variable joint positions.

\[ \begin{tabular}{|c|c|c|c|c|} \hline Joint & $a_i$ & $d_i$ & $\alpha_i$ & $\theta_i$ \\ \hline 1 & $a_1$ & $d_1$ & $-\pi/2$ & $q_1^*$ \\ 2 & $a_2$ & 0 & 0 & $q_2^*$ \\ 3 & $a_3$ & 0 & $-\pi/2$ & $q_3^* - \pi$ \\ 4 & 0 & $d_4$ & $\pi/2$ & $q_4^*$ \\ 5 & 0 & 0 & $-\pi/2$ & $q_5^*$ \\ 6 & 0 & 0 & 0 & $q_6^*-\pi$ \\ 7 & 0 & $d_6$ & 0 & 0 \\ \hline \end{tabular} \]

In this modelization, different frames have to be considered.

  • $ {\cal F}_f $: the reference frame, also called world frame
  • $ {\cal F}_w $: the wrist frame located at the intersection of the last three rotations, with $ ^f{\bf M}_w = ^0{\bf M}_6 $
  • $ {\cal F}_e $: the end-effector frame located at the interface of the two tool changers, with $^f{\bf M}_e = 0{\bf M}_7 $
  • $ {\cal F}_c $: the camera or tool frame, with $^f{\bf M}_c = ^f{\bf M}_e \; ^e{\bf M}_c $ where $ ^e{\bf M}_c $ is the result of a calibration stage. We can also consider a custom tool vpViper650::TOOL_CUSTOM and set this during robot initialisation or using set_eMc().
  • $ {\cal F}_s $: the force/torque sensor frame, with $d7=0.0666$.

This class allows to control the Viper650 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 vpViper650 class.

Warning
A Ctrl-C, a segmentation fault or other system errors are catched by this class to stop the robot.

To communicate with the robot, you may first create an instance of this class by calling the default constructor:

#include <visp3/robot/vpRobotViper650.h>
int main()
{
#ifdef VISP_HAVE_VIPER650
#endif
}
Control of Irisa's Viper S650 robot named Viper650.

This initialize the robot kinematics with the $^e{\bf M}_c$ extrinsic camera parameters obtained with a projection model without distortion. To set the robot kinematics with the $^e{\bf M}_c$ transformation obtained with a camera perspective model including distortion you need to initialize the robot with:

#include <visp3/robot/vpRobotViper650.h>
int main()
{
#ifdef VISP_HAVE_VIPER650
// Set the extrinsic camera parameters obtained with a perpective
// projection model including a distortion parameter
#endif
}
@ perspectiveProjWithDistortion
Perspective projection with distortion model.
@ TOOL_MARLIN_F033C_CAMERA
Definition: vpViper650.h:119

You can get the intrinsic camera parameters of an image acquired by the camera attached to the robot, with:

#include <visp3/core/vpCameraParameters.h>
#include <visp3/core/vpImage.h>
#include <visp3/robot/vpRobotViper650.h>
#include <visp3/sensor/vp1394TwoGrabber.h>
int main()
{
#if defined(VISP_HAVE_VIPER650) && defined(VISP_HAVE_DC1394)
g.acquire(I);
// ...
robot.getCameraParameters(cam, I);
// In cam, you get the intrinsic parameters of the projection model
// with distortion.
#endif
}
Class for firewire ieee1394 video devices using libdc1394-2.x api.
void acquire(vpImage< unsigned char > &I)
Generic class defining intrinsic camera parameters.

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

#include <visp3/core/vpColVector.h>
#include <visp3/core/vpMath.h>
#include <visp3/robot/vpRobotViper650.h>
int main()
{
#ifdef VISP_HAVE_VIPER650
// 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
robot.setPosition(vpRobot::ARTICULAR_FRAME, q);
#endif
}
Implementation of column vector and the associated operations.
Definition: vpColVector.h:163
static double rad(double deg)
Definition: vpMath.h:127
@ ARTICULAR_FRAME
Definition: vpRobot.h:78
@ STATE_POSITION_CONTROL
Initialize the position controller.
Definition: vpRobot.h:66
virtual vpRobotStateType setRobotState(const vpRobot::vpRobotStateType newState)
Definition: vpRobot.cpp:198

The robot moves to the specified position with the default positioning velocity vpRobotViper650::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/vpRobotViper650.h>
int main()
{
#ifdef VISP_HAVE_VIPER650
// Set q[i] with i in [0:5]
// Initialize the controller to position control
// Set the max velocity to 40%
robot.setPositioningVelocity(40);
// Moves the robot in the joint space
robot.setPosition(vpRobot::ARTICULAR_FRAME, q);
#endif
}

To control the robot in velocity, you may set the controller to velocity control and than 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/vpRobotViper650.h>
int main()
{
#ifdef VISP_HAVE_VIPER650
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
#endif
}
void setVelocity(const vpRobot::vpControlFrameType frame, const vpColVector &vel) vp_override
@ STATE_VELOCITY_CONTROL
Initialize the velocity controller.
Definition: vpRobot.h:65
@ STATE_STOP
Stops robot motion especially in velocity and acceleration control.
Definition: vpRobot.h:64

It is also possible to specify the position of a custom tool cartesian frame. To this end this frame is to specify with respect of the end effector frame in $^e {\bf M}_c$ transformation. This could be done by initializing the robot thanks to init(vpViper650::vpToolType, const vpHomogeneousMatrix &) or init(vpViper650::vpToolType, const std::string &) or using set_eMc(). The following example illustrates this usecase:

#include <visp3/core/vpHomogeneousMatrix.h>
#include <visp3/robot/vpRobotViper650.h>
int main()
{
#ifdef VISP_HAVE_VIPER650
// Set the transformation between the end-effector frame
// and the tool frame.
vpHomogeneousMatrix eMc(0.001, 0.0, 0.1, 0.0, 0.0, M_PI/2);
#endif
}
Implementation of an homogeneous matrix and operations on such kind of matrices.
vpHomogeneousMatrix eMc
End effector to camera transformation.
Definition: vpViper.h:154

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.

Constructor & Destructor Documentation

◆ vpRobotViper650()

vpRobotViper650::vpRobotViper650 ( bool  verbose = true)
explicit

The only available constructor.

This constructor calls init() to initialise the connection with the MotionBox or low level controller, send the default $^e{\bf M}_c$ homogeneous matrix and power on the robot.

It also set the robot state to vpRobot::STATE_STOP.

To set the extrinsic camera parameters related to the $^e{\bf M}_c$ matrix obtained with a camera perspective projection model including the distortion, use the code below:

#include <visp3/core/vpCameraParameters.h>
#include <visp3/core/vpImage.h>
#include <visp3/robot/vpRobotViper650.h>
#include <visp3/sensor/vp1394TwoGrabber.h>
int main()
{
#ifdef VISP_HAVE_VIPER650
// Set the extrinsic camera parameters obtained with a perpective
// projection model including a distortion parameter

Now, you can get the intrinsic camera parameters associated to an image acquired by the camera attached to the robot, with:

// Get an image from the camera attached to the robot
#ifdef VISP_HAVE_DC1394
g.acquire(I);
#endif
robot.getCameraParameters(cam, I);
// In cam, you get the intrinsic parameters of the projection model
// with distortion.
#endif
}

q: In input, a six dimension vector corresponding to the current joint positions expressed in radians. In output, the solution of the inverse kinematics, ie. the joint positions corresponding to $^f{\bf M}_w $.
verbose: Add extra printings.
Returns
Add printings if no solution was found.
The number of solutions (1 to 8) of the inverse geometric model. O, if no solution can be found.

The code below shows how to compute the inverse geometric model:

vpColVector q1(6), q2(6);
vpViper robot;
// Get the current joint position of the robot
robot.getPosition(vpRobot::ARTICULAR_FRAME, q1);
// Compute the pose of the wrist in the reference frame using the
// direct geometric model
robot.get_fMw(q1, fMw);
// Compute the inverse geometric model
int nbsol; // number of solutions (0, 1 to 8) of the inverse geometric model
// get the nearest solution to the current joint position
nbsol = robot.getInverseKinematicsWrist(fMw, q1);
if (nbsol == 0)
std::cout << "No solution of the inverse geometric model " << std::endl;
else if (nbsol >= 1)
std::cout << "Nearest solution: " << q1 << std::endl;

◆ init() [2/5]

void vpRobotViper650::init ( void  )
virtual

Initialise the connection with the MotionBox or low level controller, send the default eMc homogeneous matrix, power on the robot and wait 1 sec before returning to be sure the initialisation is done.

Warning
This method sets the camera extrinsic parameters (matrix eMc) to the one obtained by calibration with a camera projection model without distortion by calling init(vpViper650::defaultCameraRobot). If you want to set the extrinsic camera parameters to those obtained with a camera perspective model including the distortion you have to call the init(vpViper650::vpToolType, vpCameraParameters::vpCameraParametersProjType) method. If you want to set custom extrinsic camera parameters you have to call the init(vpViper650::vpToolType, const vpHomogeneousMatrix&) method.

◆ init() [5/5]

Initialize the robot kinematics with the extrinsic calibration parameters associated to a specific camera (set the eMc homogeneous parameters in the low level controller) and also get the joint limits from the low-level controller.

The eMc parameters depend on the camera and the projection model in use.

Parameters
tool: Tool to use.
projModel: Projection model associated to the camera.

To set the extrinsic camera parameters related to the $^e{\bf M}_c$ matrix obtained with a camera perspective projection model including the distortion, use the code below:

int main()
{
#ifdef VISP_HAVE_VIPER650
// Set the extrinsic camera parameters obtained with a perpective
// projection model including a distortion parameter

Now, you can get the intrinsic camera parameters associated to an image acquired by the camera attached to the robot, with:

// Get an image from the camera attached to the robot
#ifdef VISP_HAVE_DC1394
g.acquire(I);
#endif
robot.getCameraParameters(cam, I);

◆ readPosFile()

bool vpRobotViper650::readPosFile ( const std::string &  filename,
vpColVector q 
)
static

Read joint positions in a specific Viper650 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/vpRobotViper650.h>
int main()
{
#ifdef VISP_HAVE_VIPER650
// Enable the position control of the robot
// 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

◆ savePosFile()

bool vpRobotViper650::savePosFile ( const std::string &  filename,
const vpColVector q 
)
static

Save joint (articular) positions in a specific Viper650 position file.

This position file starts with a header on the first line. After convertion of the rotations in degrees, the joint position q is written on a line starting with the keyword "R: ". See readPosFile() documentation for an example of such a file.

Parameters
filename: Name of the position file to create.
q: The six joint positions to save in the filename. Values are expressed in radians.
Warning
All the six joint rotations written in the file are converted in degrees to be more representative for the user.
Returns
true if the positions were successfully saved in the file. false, if an error occurs.

◆ setVelocity()

void vpRobotViper650::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. Translation velocities are expressed in m/s while rotation velocities in rad/s. 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 authorized speed (see vpRobot::maxTranslationVelocity and vpRobot::maxRotationVelocity). To change these values use setMaxTranslationVelocity() and setMaxRotationVelocity().
