2014-05-25 10:18:30 -0500 | commented answer | Global path not changing despite newly discovered obstacle hi dear Ernest , i have exactly the same problem . is your problem solved ? , if yes , how can i force the trajectory planner to generate dynamic paths when an obstacle comes in front of robot ... ?! if any body have any idea its my pleasure to hear them . |
2014-05-24 07:15:45 -0500 | answered a question | Does the navigation stack require a map you can use the navigation stack without any static map , just with set static map for both global and local false and windowing true , then you can get /map data from hector_slam and use it for your navigation . |

2014-05-24 06:40:21 -0500 | commented question | move_base and hector_slam hi David , i am using hydro , i solved my problem by publishing a fake optometry data using hector_slam position . only the speed of robot is computed from robot encoders . now my robot can navigate and follow the trajectory path to rich the goal . i don't use static map ( map server and amcl ) so for both local and global parameters , i set the static parameter false and windowing is true . |
2014-05-18 22:45:09 -0500 | asked a question | move_base and hector_slam hi , i am working on a mobile robot with ROS , and i want to have navigation ability without any odometry data from my motors . hector_slam is run very good and i have no problem with it , i can get pos and yaw of my robot with a hokuyo laser sensor . the map is published to /map topic . for navigation and planning i want to use the move_base without map_server and AMCL . i dont have any odom topic . what is the launch file for do this exactly? what is the param config for move_base , because there is no update for costmaps from rviz ?! ... i seems its not get my /map topic for calculations... ? ( global_cost_map is STATIC , local_cost_map is not STATIC and windowing is enabled !? . 1 ) how can i send /map to move_base ? 2 ) why we need odom tf ( odom => base_link ) ? 3 ) is odom topic necessary for move_base? 4 ) what is paramers config for move_base for dynamic SLAM navigation ? 5 ) what is a launch file for this to get worked ? thx for any reply :) .... i just confused a bit :( . |
