practical example for plot position(x y z) of fixed frames(end-effector) in rqt [closed]
hi . i searched and searched but couldn't find any example for plot position(x y z) of fixed frames(end-effector) in rqt .
@gvdhorn told you that plotting tf-frames as it is not possible to access your end-effector pose with rqt as it's not published. Write a node that uses tf to get the pose and publish it on a topic that you then visualize in rqt_plot.
but i need practical example
start with a tf client http://wiki.ros.org/tf/TfUsingPython and publish your coordinates
thanks a lot
