Detailed Description

Generic functions for Pioneer mobile robots.

This class provides common features for Pioneer mobile robots. This robot has two control velocities $(v_x, w_z)$ , the translational and rotational velocities of the mobile platform 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 middle point between the two wheels.

The robot jacobian at the end effector frame, the point located at the middle between the two wheels is given by:

${^e}{\bf J}_e = \left(\begin{array}{cc} 1 & 0 \\ 0 & 0 \\ 0 & 0 \\ 0 & 0 \\ 0 & 0 \\ 0 & 1 \\ \end{array} \right)$

Considering $(v_x, w_z)$ , it is possible to compute $\bf v$ the six dimention velocity skew expressed at the end effector frame by:

${\bf v} = {^e}{\bf J}_e \; \left(\begin{array}{c} v_x \\ w_z \\ \end{array} \right)$

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, servoPioneerPoint2DDepthWithoutVpServo.cpp, tutorial-simu-pioneer-pan.cpp, and tutorial-simu-pioneer.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.

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 ${\bf v} = {^e}{\bf J}_e \; \dot{\bf q}$ with $\dot{\bf q} = (v_x, w_z)$ the robot control velocities and $\bf v$ the six dimention velocity skew.
