Detailed Description

Modelisation of the ADEPT Viper 850 robot.

The model of the robot is the following:

model-viper.png
Model of the Viper 850 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 modelisation, 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 TOOL_CUSTOM and set this during robot initialisation or using set_eMc().
  • $ {\cal F}_s $: the force/torque sensor frame, with $d7=0.0666$.

void vpViper850::getCameraParameters ( vpCameraParameters &  cam,

Get the current intrinsic camera parameters obtained by calibration.

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_XML2 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_XML2 macros are defined, this method gets the camera parameters from const_camera_Viper850.xml config file.
  • If these two macros are not defined, this method set the camera parameters to default one.
Parameters
cam: In output, camera parameters to fill.
image_width: Image width used to compute camera calibration.
image_height: Image height used to compute camera calibration.

The code below shows how to get the camera parameters of the camera attached to the robot.

void vpViper850::getCameraParameters ( vpCameraParameters &  cam,
const vpImage< unsigned char > &  I 
) const

Get the current intrinsic camera parameters obtained by calibration.

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_XML2 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_XML2 macros are defined, this method gets the camera parameters from const_camera_Viper850.xml config file.
  • If these two macros are not defined, this method set the camera parameters to default one.
Parameters
cam: In output, camera parameters to fill.
I: A B&W image send by the current camera in use.

Return the coupling factor between join 5 and joint 6.

This factor should be only useful when motor positions are considered. Since the positions returned by the robot are joint positions which takes into account the coupling factor, it has not to be considered in the modelization of the robot.

vpHomogeneousMatrix vpViper::getForwardKinematics ( const vpColVector &  q) const
inherited

Compute the forward kinematics (direct geometric model) as an homogeneous matrix.

By forward kinematics we mean here the position and the orientation of the camera relative to the base frame given the six joint positions.

This method is the same than get_fMc(const vpColVector & q).

Parameters
q: A six dimension vector corresponding to the robot joint positions expressed in radians.
Returns
The homogeneous matrix $^f{\bf M}_c $ corresponding to the direct geometric model which expresses the transformation between the base frame and the camera frame.

By inverse kinematics we mean here the six joint values given the position and the orientation of the camera frame relative to the base frame.

Parameters

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}_c $.
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);
vpHomogeneousMatrix fMc;
vpViper robot;
// Get the current joint position of the robot
robot.getPosition(vpRobot::ARTICULAR_FRAME, q1);
// Compute the pose of the camera in the reference frame using the

fMc = robot.getForwardKinematics(q1);
// this is similar to fMc = robot.get_fMc(q1);
// or robot.get_fMc(q1, fMc);
// 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.getInverseKinematics(fMc, q1);
