So you suggest the tf config like this: /map /map/wheel_odometry (just for show) /map/odom /map/odom/base /map/odom/base/laser So "map" contains the current (relative) drift of odom to compensate slip ? Ah ok... By the way, how do i read out the current angular/translative velocities ? There are only tutorials how to publish them, but not how to read them out ! thanks://Sven -- View this message in context: http://ros-users.122217.n3.nabble.com/tf-Node-paradox-amcl-tp994748p996527.html Sent from the ROS-Users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ The Palm PDK Hot Apps Program offers developers who use the Plug-In Development Kit to bring their C/C++ apps to Palm for a share of $1 Million in cash or HP Products.
