2012年11月5日 · The output of the EKF seems to be nice, and if it's relevant publishes the position in UTM's. The problems start when I use the AMCL for doing the localization on the map. When I run the AMCL, the particles cloud begins to diverge, and then the localization is very poor and the move_base package can't make the robot move very well.

2021年2月4日 · My next step is use amcl to locate my robot on map but Amcl Particales dose not change at all, even though i move my robot around. Any body please help me about this situation. And sorry because my English. Detail of trouble: Robot: build from my self. Lidar: RPLIDAR A1, running on jetson nano. System: Ros Noetic on Ubutu 20.04.

Hi, I have been struggling at tuning the amcl parameters. No matter how I tuned it the result is is not that ideal here. Below is my amcl config. I plotted the amcl poses into a path. Green is odom, red is amcl, blue is amcl_ekf. I understand that ekf has helped a lot in localising it but I would like to improve amcl too.

2012年12月6日 · My problem is: If i start amcl it is not publishing the transform from map->odom. I'm getting the warning "Waiting on transform from /base_link to /map to become available before running costmap, tf error:" So in my understanding amcl should provide the missing transform map->odom to finish the tf tree.

2023年6月14日 · I am using a ROS Noetic, with the ubuntu 20.0.4. I am trying to configure the navigation stack, with the amcl so that it will has a pose update as well as 2D Nav Goal.

2021年10月5日 · To launch the example above, just place all files in the same folder and run the command (make sure that you have the amcl and map_server packages installed. I am using the 1.17.1 version of the navigation stack on ROS Noetic, Ubuntu 20.04): LAUNCH_DIR=`pwd` roslaunch launch_amcl.launch

2017年7月17日 · Please turn the [ros.amcandl.message_notifier] rosconsole logger to DEBUG for more information. so I did as said and got: [DEBUG] [1500393934.597976349]: MessageFilter [target=odom ]: Removed oldest message because buffer is full, count [DEBUG] [1500393933.564483123]: MessageFilter [target=odom ]: Added message in …

I was reading up on ROS's navigation stack as well as amcl 's documentation when I realized from the stack's diagram that move_base does not subscribe to /amcl_pose , which amcl uses to publish the robot's estimated pose in the map. In that case how does move_base update the current localized pose of the robot ? Thanks

2019年11月19日 · According to rep-105, you have world -> map -> odom -> base_link, you get odom -> base_link from amcl and map -> odom from gmapping, so you cannot get rid of amcl, unless you provide some other source of odometry like robot_localization. Or use some lidar or camera Odometry method. And move_base requires odom to work in expected manner.

2020年1月15日 · Hi, i am relativly new to the whole ros and robot topic. I got a RPlidar A1 and what i want to do is to retrieve a x and y position (respectivly to the given map which i create with hector_gmapping as a yaml file). I already set up the workspace and installed the packages (navigation, hectorslam, rplidar etc).
