Detailed Description

Control of Irisa's gantry robot named Afma6.

Implementation of the vpRobot class in order to control Irisa's Afma6 robot. This robot is a gantry robot with six degrees of freedom manufactured in 1992 by the french Afma-Robots company. In 2008, the low level controller change for a more recent Adept technology based on the MotionBlox controller. 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. A ring light is attached around the camera. The control of this ring light is possible throw the vpRingLight class. A CCMOP gripper is also mounted on the end-effector. The pneumatic control of this gripper is possible throw the openGripper() or closeGripper() member functions.

This class allows to control the Afma6 gantry 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 vpAfma6 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/vpRobotAfma6.h>
#ifdef VISP_HAVE_AFMA6
int main()
{
  vpRobotAfma6 robot;
}
#else
int main() {}
#endif

This initialize the robot kinematics with the eMc extrinsic camera parameters obtained with a projection model without distortion. To set the robot kinematics with the eMc matrix obtained with a camera perspective model including distortion you need to initialize the robot with:

// Set the extrinsic camera parameters obtained with a perpective
// projection model including a distortion parameter
robot.init(vpAfma6::TOOL_CCMOP, vpCameraParameters::perspectiveProjWithDistortion);

You can get the intrinsic camera parameters of the image I acquired with the camera, with:

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

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:

vpColVector q(6);
// Set a joint position
q[0] = 0.1; // x axis, in meter
q[1] = 0.2; // y axis, in meter
q[2] = 0.3; // z axis, in meter
q[3] = M_PI/8; // rotation around A axis, in rad
q[4] = M_PI/4; // rotation around B axis, in rad
q[5] = M_PI;   // rotation around C axis, 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);

The robot moves to the specified position with the default positioning velocity vpRobotAfma6::defaultPositioningVelocity. The setPositioningVelocity() method allows to change the maximal velocity used to reach the desired position.

// Set the max velocity to 40%
robot.setPositioningVelocity(40);
// Moves the robot in the joint space
robot.setPosition(vpRobot::ARTICULAR_FRAME, q);

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:

vpColVector qvel(6);
// Set a joint velocity
qvel[0] = 0.1;    // x axis, in m/s
qvel[1] = 0.2;    // y axis, in m/s
qvel[2] = 0;      // z axis, in m/s
qvel[3] = M_PI/8; // rotation around A axis, in rad/s
qvel[4] = 0;      // rotation around B axis, in rad/s
qvel[5] = 0;      // rotation around C axis, in rad/s
// Initialize the controller to position control
robot.setRobotState(vpRobot::STATE_VELOCITY_CONTROL);
while (...) {
  // 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)

There 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 writePosFile() methods.

Constructor & Destructor Documentation

vpRobotAfma6::vpRobotAfma6 ( bool verbose = true )

explicit

The only available constructor.

This contructor calls init() to 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.

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

To set the extrinsic camera parameters related to the eMc matrix obtained with a camera perspective projection model including the distorsion, use the code below:

vpRobotAfma6 robot;
// Set the extrinsic camera parameters obtained with a perpective
// projection model including a distorsion parameter
robot.init(vpAfma6::TOOL_CCMOP,
vpCameraParameters::perspectiveProjWithDistortion); 

Now, you can get the intrinsic camera parameters of the image I acquired with the camera, with:

vpCameraParameters cam;
robot.getCameraParameters(cam, I);
// In cam, you get the intrinsic parameters of the projection model
// with distorsion.

vpHomogeneousMatrix vpAfma6::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 articular positions of all the six joints.

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

Parameters

q	: Articular position of the six joints: q[0], q[1], q[2] correspond to the first 3 translations expressed in meter, while q[3], q[4] and q[5] correspond to the 3 succesives rotations expressed in radians.

Returns: The homogeneous matrix corresponding to the direct geometric model which expresses the transformation between the base frame and the camera frame (fMc).

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

Parameters

fMc	: Homogeneous matrix describing the transformation from base frame to the camera frame.
q	: In input, the current articular joint position of the robot. In output, the solution of the inverse kinematics. Articular position of the six joints: q[0], q[1], q[2] correspond to the first 3 translations expressed in meter, while q[3], q[4] and q[5] correspond to the 3 succesives rotations expressed in radians.
nearest	: true to return the nearest solution to q. false to return the farest.
verbose	: Activates printings when no solution is found.

Returns: The number of solutions (1 or 2) of the inverse geometric model. O, if no solution can be found.

void vpRobotAfma6::init	(	vpAfma6::vpAfma6ToolType	tool,
		const std::string &	filename
	)

Initialize the robot kinematics (set the eMc homogeneous parameters in the low level controller) from a file and also get the joint limits from the low-level controller.

Parameters

tool	: Tool to use.
filename	: Path of the configuration file containing the transformation between the end-effector frame and the tool frame.

To set the transformation parameters related to the $^e{\bf M}_c$ matrix, use the code below:

#include <visp3/robot/vpRobotAfma6.h>
int main()
{
#ifdef VISP_HAVE_AFMA6
  vpRobotAfma6 robot;
  // Set the transformation between the end-effector frame
  // and the tool frame from a file
  std::string filename("./EffectorToolTransformation.cnf");
  robot.init(vpAfma6::TOOL_CUSTOM, filename);
#endif
}

The configuration file should have the form below:

# Start with any number of consecutive lines
# beginning with the symbol '#'
#
# The 3 following lines contain the name of the camera,
# the rotation parameters of the geometric transformation
# using the Euler angles in degrees with convention XYZ and
# the translation parameters expressed in meters

void vpRobotAfma6::init	(	vpAfma6::vpAfma6ToolType	tool,
		vpCameraParameters::vpCameraParametersProjType	projModel = `vpCameraParameters::perspectiveProjWithoutDistortion`
	)

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 eMc matrix obtained with a camera perspective projection model including the distorsion, use the code below:

vpRobotAfma6 robot;
// Set the extrinsic camera parameters obtained with a perpective
// projection model including a distorsion parameter
robot.init(vpAfma6::TOOL_CCMOP,
vpCameraParameters::perspectiveProjWithDistortion); 

Now, you can get the intrinsic camera parameters of the image I acquired with the camera, with:

vpCameraParameters cam;
robot.getCameraParameters(cam, I);
// In cam, you get the intrinsic parameters of the projection model
// with distorsion.

bool vpRobotAfma6::readPosFile	(	const std::string &	filename,
		vpColVector &	q
	)

static

Read joint positions in a specific Afma6 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:

#AFMA6 - Position - Version 2.01
# file: "myposition.pos "
#
# R: X Y Z A B C
# Joint position: X, Y, Z: translations in meters
#                 A, B, C: rotations in degrees
#
R: 0.1 0.3 -0.25 -80.5 80 0

Parameters

filename	: Name of the position file to read.
q	: Joint positions: X,Y,Z,A,B,C. Translations X,Y,Z are expressed in meters, while joint rotations A,B,C 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.

vpRobotAfma6 robot;
vpColVector q;        // Joint position
robot.readPosFile("myposition.pos", q); // Set the joint position from the file
robot.setRobotState(vpRobot::STATE_POSITION_CONTROL);
robot.setPositioningVelocity(5); // Positioning velocity set to 5%
robot.setPosition(vpRobot::ARTICULAR_FRAME, q); // Move to the joint position

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().

// Set joint velocities
vpColVector q_dot(6);
q_dot[0] = 0.1;    // X axis, in meter/s
q_dot[1] = 0.2;    // Y axis, in meter/s
q_dot[2] = 0.3;    // Z axis, in meter/s
q_dot[3] = M_PI/8; // A axis, in rad/s
q_dot[4] = M_PI/4; // B axis, in rad/s
q_dot[5] = M_PI/16;// C axis, in rad/s
vpRobotAfma6 robot;
robot.setRobotState(vpRobot::STATE_VELOCITY_CONTROL);
// Moves the joint in velocity
robot.setVelocity(vpRobot::ARTICULAR_FRAME, q_dot);
