autonomous_chair

Overview

localization of a autonomous chair with cartographer

Keywords: localization, cartographer

The autonomous_chair package has been tested under ROS Kinetic and Ubuntu 16.04. This is research code, expect that it changes often and any fitness for a particular purpose is disclaimed.

Installation

Installation from Packages

Building

To build from source, clone the latest version from this repository into your catkin workspace and compile the package using

cd catkin_workspace/src
git clone https://github.com/manuelilg/autonomous_chair.git
cd ../
rosdep update
rosdep install --from-paths src --ignore-src -r -y
catkin build

Usage

####How to create a map:

1. Record data while driving in the environment:

    roslaunch autonomous_chair_cartographer record.launch
   

2. Run offline cartographer node (creates .pbstream-file):

    roslaunch autonomous_chair_cartographer offline_chair.launch
   

3. Create map:

    roslaunch autonomous_chair_cartographer offline_map_creation.launch
   

####Run localisation on a given map:

roslaunch autonomous_chair_cartographer localisation.launch

####Run a simple simulation of the chair:

roslaunch roslaunch autonomous_chair_gazebo chair_world.launch

####Visualize the chair and the laser-scan data (real or simulated chair):

roslaunch autonomous_chair_description rviz.launch

Launch files

• record.launch: Starts rosbag record

  Note:

  • bag-file will be saved in the directory from where the launch-file have been started

• offline_chair.launch: start offline slam

  Argument set 1

  • bag_filenames Absolute path to bag-file
  • no_rviz Set to false to see the progress of the SLAM-Prozess. Default: true.

  Note:

  • pbstream-file will be in the same directory as the bag-file

• offline_map_creation.launch: start offline slam

  Argument set 1

  • bag_filenames Absolute path to bag-file

  Note:

  • the map-files will will be in the same directory as the bag-file/pbstream-file

• localisation.launch: start localisation

  Argument set 1

  • pbstream_file Absolute path to pbstream-file
  • map_file Absolute path to map-file (yaml)
  • initial_pose initial-pose in the given map.
    Default: translation={0.0, 0.0, 0.0}, rotation={0.0, 0.0, 0.0}

• chair_world.launch: start localisation

  Argument set 1

  • pbstream_file Absolute path to pbstream-file
  • map_file Absolute path to map-file (yaml)
  • initial_pose initial-pose in the given map.
    Default: translation={0.0, 0.0, 0.0}, rotation={0.0, 0.0, 0.0}

Config files

Config file in dir: autonomous_chair_description/configuration_files

• chair.lua cartographer configuration-file for SLAM (settings maybe need to be tuned)
• chair_localisation.lua.lua cartographer configuration-file for localisation (settings maybe need to be tuned)
