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.
The model of the robot is the following:
The non modified Denavit-Hartenberg representation of the robot is given in the table below, where 
are the variable joint positions.
![\[\begin{tabular}{|c|c|c|c|c|}

In this modelization, different frames have to be considered.
: the reference frame, also called world frame
: the wrist frame located at the intersection of the last three rotations, with 
: the end-effector frame located at the interface of the two tool changers, with 
: the camera or tool frame, with 
where 
is the result of a calibration stage. We can also consider a custom tool vpViper850::TOOL_CUSTOM and set this during robot initialisation or using set_eMc().
: the force/torque sensor frame, with 
.This class allows to control the Viper650 arm robot in position and velocity:
(vpRobot::REFERENCE_FRAME), (vpRobot::CAMERA_FRAME), and rotations in the camera or tool 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 communicate with the robot, you may first create an instance of this class by calling the default constructor:
This initialize the robot kinematics with the 
extrinsic camera parameters obtained with a projection model without distortion. To set the robot kinematics with the transformation obtained with a camera perspective model including distortion you need to initialize the robot with:
You can get the intrinsic camera parameters of an image acquired by the camera attached to the robot, with:
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:
The robot moves to the specified position with the default positioning velocity vpRobotViper850::m_defaultPositioningVelocity. The setPositioningVelocity() method allows to change the maximal velocity used to reach the desired position.
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:
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 
transformation. This could be done by initializing the robot thanks to init(vpViper850::vpToolType, const vpHomogeneousMatrix &) or init(vpViper850::vpToolType, const std::string &) or using set_eMc(). The following example illustrates this usecase:
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.

The only available constructor.
This constructor calls init() to initialise the connection with the MotionBox or low level controller, send the default 
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 matrix obtained with a camera perspective projection model including the distortion, use the code below:

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:
