I want to know How can I use ROS Rviz to visualize a robot's movement; like drawing lines to show the distance moved by the robot. and shapes like squares to show the place of detected objects?

Hey, You can use [RViz Markers] (http://wiki.ros.org/rviz/DisplayTypes...) (for both C++ and Python). There are many types that you could use to describe the shape of the object detected as well. You just have to subscribe to the detected object's state (position, orientation or velocity...) and then publish an RViz marker (arrow, cube, point...) at that state.

thank you, what about drawing the route the robot walked. and I found only C++ code, how can I do it with python?
