  \class vpRobotViper850

  \ingroup Viper RobotDriver

  \brief Control of Irisa's Viper S850 robot named Viper850.

  Implementation of the vpRobot class in order to control Irisa's
  Viper850 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.

  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.

  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.

  \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:

  \code
#include <visp/vpConfig.h>
#include <visp/vpRobotViper850.h>

int main()
{
#ifdef VISP_HAVE_VIPER850
  vpRobotViper850 robot;
#endif
}
  \endcode

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

  \code
#include <visp/vpConfig.h>
#include <visp/vpRobotViper850.h>

int main()
{
#ifdef VISP_HAVE_VIPER850
  vpRobotViper850 robot;

  // Set the extrinsic camera parameters obtained with a perpective 
  // projection model including a distortion parameter
  robot.init(vpViper850::TOOL_MARLIN_F033C_CAMERA,
	     vpCameraParameters::perspectiveProjWithDistortion);
#endif
}
  \endcode

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

  \code
#include <visp/vpConfig.h>
#include <visp/vpRobotViper850.h>
#include <visp/vpImage.h>
#include <visp/vp1394TwoGrabber.h>
#include <visp/vpCameraParameters.h>

int main()
{
#if defined(VISP_HAVE_VIPER850) && defined(VISP_HAVE_DC1394_2)
  vpImage<unsigned char> I;
  vp1394TwoGrabber g;
  g.acquire(I);

  vpRobotViper850 robot;

  // ...

  vpCameraParameters cam;
  robot.getCameraParameters(cam, I);
  // In cam, you get the intrinsic parameters of the projection model 
  // with distortion.
#endif
}
  \endcode

  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:

  \code
#include <visp/vpConfig.h>
#include <visp/vpRobotViper850.h>
#include <visp/vpColVector.h>
#include <visp/vpMath.h>

int main()
{
#ifdef VISP_HAVE_VIPER850
  vpRobotViper850 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);
#endif
}
  \endcode

  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.

  \code
#include <visp/vpConfig.h>
#include <visp/vpRobotViper850.h>
#include <visp/vpColVector.h>
#include <visp/vpMath.h>

int main()
{
#ifdef VISP_HAVE_VIPER850
  vpRobotViper850 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);
#endif
}
  \endcode

  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:

  \code
#include <visp/vpConfig.h>
#include <visp/vpRobotViper850.h>
#include <visp/vpColVector.h>
#include <visp/vpMath.h>

int main()
{
#ifdef VISP_HAVE_VIPER850
  vpRobotViper850 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);
#endif
}
  \endcode

  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.
