[ros-users] Rviz and URDF split

Hi All
I'm running c turtle on ubuntu 10.4 i have a URDF with 4 parts and 3
joints which displays fine in rviz
my problem starts when i use tele_op to move the robot the base link
stays fixed on the map / grid and the upper_base
head and base_laser move in sync with the tele_op commands. The upper
body assy flashes between the base link and where it stopped
or it just drifts between the 2

rosrun tf tf_echo /map /base_link gives the following result

the robot has not move at all but Rviz was drifring

rviz fixed frame is /map
and target frame is <fixed frame>

I have change the reference frames but no improvment
