Detailed Description

Generic functions for Pioneer mobile robots equiped with a pan head.

This class provides common features for Pioneer mobile robots equiped with a pan head.

This robot has three control velocities $(v_x, w_z, \dot{q_1})$ , the translational and rotational velocities of the mobile platform, the pan head velocity respectively.

The figure below shows the position of the frames that are used to model the robot. The end effector frame is here located at the pan axis.

Member Function Documentation

vpHomogeneousMatrix vpUnicycle::get_cMe ( ) const

inlineinherited

Return the tranformation ${^c}{\bf M}_e$ between the camera frame and the mobile robot end effector frame.

Definition at line 78 of file vpUnicycle.h.

vpVelocityTwistMatrix vpUnicycle::get_cVe ( ) const

inlineinherited

Return the twist transformation from camera frame to the mobile robot end effector frame. This transformation allows to compute a velocity expressed in the end effector frame into the camera frame.

Examples:: servoPioneerPanSegment3D.cpp, servoPioneerPoint2DDepth.cpp, and servoPioneerPoint2DDepthWithoutVpServo.cpp.

void vpUnicycle::get_cVe ( vpVelocityTwistMatrix & cVe ) const

inlineinherited

Return the twist transformation from camera frame to the mobile robot end effector frame. This transformation allows to compute a velocity expressed in the end effector frame into the camera frame.

References vpUnicycle::get_cVe().

vpMatrix vpUnicycle::get_eJe ( ) const

inlineinherited

Return the robot jacobian ${^e}{\bf J}_e$ expressed in the end effector frame.

Returns: The robot jacobian such as ${\bf v} = {^e}{\bf J}_e \; \dot{q}$ with ${\bf q}$ the robot control velocities and $\bf v$ the six dimention velocity skew.

void vpUnicycle::set_cMe ( const vpHomogeneousMatrix & cMe )

inlineinherited

Set the transformation between the camera frame and the end effector frame.

void vpPioneerPan::set_eJe ( double q_pan )

inline

Set the robot jacobian expressed at point E the end effector frame located on the pan head.

Considering ${\bf v} = {^e}{\bf J}_e \; [v_x, w_z, \dot{q_1}]$ with $(v_x, w_z)$ respectively the translational and rotational control velocities of the mobile platform, $\dot{q_1}$ the joint velocity of the pan head and $\bf v$ the six dimention velocity skew expressed at point E in frame E, the robot jacobian is given by:

${^e}{\bf J}_e = \left(\begin{array}{ccc} c_1 & -c_1*p_y - s_1*p_x & 0 \\ 0 & 0 & 0 \\ s_1 & -s_1*p_y + c_1*p_x & 0 \\ 0 & 0 & 0 \\ 0 & -1 & 1 \\ 0 & 0 & 0 \\ \end{array} \right)$

with $p_x, p_y$ the position of the head base frame in the mobile platform frame located at the middle point between the two weels.

Examples:: servoPioneerPanSegment3D.cpp.

Definition at line 112 of file vpPioneerPan.h.

void vpUnicycle::set_eJe ( const vpMatrix & eJe )

inlineinherited

Set the robot jacobian ${^e}{\bf J}_e$ expressed in the end effector frame.

Parameters

eJe	: The robot jacobian to set such as ${\bf v} = {^e}{\bf J}_e \; \dot{q}$ with ${\bf q}$ the robot control velocities and $\bf v$ the six dimention velocity skew.
