I confirmed that als_ros works on **Ubuntu 18.04** with melodic and **Ubuntu 20.04** with noetic. 21 | 22 | als_ros can be installed with following commands. 23 | 24 | ``` 25 | $ git clone https://github.com/NaokiAkai/als_ros.git 26 | $ cd als_ros 27 | $ catkin_make 28 | $ source devel/setup.bash 29 | ``` 30 | 31 | If you do not want to make a new workspace for als_ros, please copy the als_ros package to your workspace. The cloned directory has a ROS workspace. 32 | 33 | 34 | 35 | ## How to use 36 | 37 | Following messages (topics) are needed to be published; 38 | 39 | - sensor_msgs::LaserScan (/scan) 40 | - nav_msgs::Odometry (/odom) 41 | - nav_msgs::OccupancyGrid (/map) 42 | 43 | Names inside of the brackets are default topic names. 44 | 45 | Also, static transformation between following two frames is needed to be set. 46 | 47 | - origin of a robot (base_link) 48 | - 2D LiDAR (laser) 49 | 50 | Names inside of the brackets are default frame names. 51 | 52 | There are launch files in the als_ros package. These names can be changed in **mcl.launch**. 53 | 54 | 55 | 56 | After setting the topics and transformation, the localization software can be used with mcl.launch. 57 | 58 | ``` 59 | $ roslaunch als_ros mcl.launch 60 | ``` 61 | 62 | In default, localization for pose tracking with the robust localization and reliability estimation techniques presented in [2, 3] is executed. 63 | 64 | 65 | 66 | If you want to use fusion of pose tracking and global localization, please set use_gl_pose_sampler flag to true. 67 | 68 | ``` 69 | $ roslaunch als_ros mcl.launch use_gl_pose_sampler:=true 70 | ``` 71 | 72 | In als_ros, global localization is implemented using the free-space feature presented in [6]. 73 | 74 | 75 | 76 | If you want to use estimation of localization failure probability with misalignment recognition, please set use_mrf_failure_detector flag to true. 77 | 78 | ``` 79 | $ roslaunch als_ros mcl.launch use_mrf_failure_detector:=true 80 | ``` 81 | 82 | 83 | 84 | ## Parameter descriptions 85 | 86 | Descriptions for all the parameters are written in the launch files. I am planning to make a more precise document. 87 | 88 | 89 | 90 | # Citation 91 | 92 | [arXiv preprint](https://arxiv.org/abs/2205.04769) and [journal paper](https://onlinelibrary.wiley.com/doi/abs/10.1002/rob.22149) are available.
