how get pose(x,y,z) of links and plot in rqt?
hi. I want plot position (x y z) for camera and second link for RRRBot robot.
NEngelhard told me: " you need to use a tf listener to get the pose and republish these values so that rqt_plot is able to plot them. "
but I do not know what to do. can any body write tf listener for RRRBot robot ??
