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.

Considering

${\bf v} = {^e}{\bf J}_e \; \left(\begin{array}{c} v_x \\ w_z \\ \dot{q_1} \\ \end{array} \right)$

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.
