# Limo Simulation Operation Process
## 1. Introduction of Function Package
```
├── image
├── limo_description
├── limo_gazebo_sim
```
limo_description: The file is the function package of model file
limo_gazebo_sim: The folder is gazebo simulation function package
## 2. Environment
### Development Environment
ubuntu 18.04 + [ROS Melodic desktop full](http://wiki.ros.org/melodic/Installation/Ubuntu)
### Download and install required function package
Download and install ros-control function package, ros-control is the robot control middleware provided by ROS
```
sudo apt-get install ros-melodic-ros-control
```
Download and install ros-controllers function package, ros-controllers are the kinematics plug-in of common models provided by ROS
```
sudo apt-get install ros-melodic-ros-controllers
```
Download and install gazebo-ros function package, gazebo-ros is the communication interface between gazebo and ROS, and connect the ROS and Gazebo
```
sudo apt-get install ros-melodic-gazebo-ros
```
Download and install gazebo-ros-control function package, gazebo-ros-control is the communication standard controller between ROS and Gazebo
```
sudo apt-get install ros-melodic-gazebo-ros-control
```
Download and install rqt-robot-steering plug-in, rqt_robot_steering is a ROS tool closely related to robot motion control, it can send the control command of robot linear motion and steering motion, and the robot motion can be easily controlled through the sliding bar
```
sudo apt-get install ros-melodic-rqt-robot-steering
```
Download and install teleop-twist-keyboard function package, telop-twist-keyboard is keyboard control function package, the robot can be controlled to move forward, left, right and backward through "i", "j", "l",and "," on the keyboard
```
sudo apt-get install ros-melodic-teleop-twist-keyboard
```
## 3. About Usage
### 1. Create workspace, download simulation model function package and compile
Open a new terminal and create a workspace named limo_ws, enter in the terminal:
```
mkdir limo_ws
```
Enter the limo_ws folder
```
cd limo_ws
```
Create a folder to store function package named src
```
mkdir src
```
Enter the src folder
```
cd src
```
Initialize folder
```
catkin_init_workspace
```
Download simulation model function package
```
git clone https://github.com/agilexrobotics/ugv_sim/limo.git
```
Enter the limo_ws folder
```
cd limo_ws
```
Confirm whether the dependency of the function package is installed
```
rosdep install --from-paths src --ignore-src -r -y
```
Compile
```
catkin_make
```
### 2. Run the star file of limo model and visualize the urdf file in Rviz
Enter the limo_ws folder
```
cd limo_ws
```
Declare the environment variable
```
source devel/setup.bash
```
Run the start file of limo and visualize the model in Rviz
roslaunch limo_description display_models.launch
![img](image/rviz.png)
### 3. Start the gazebo simulation environment of limo and control limo movement in the gazebo
Enter the limo_ws folder
```
cd limo_ws
```
Declare the environment variable
```
source devel/setup.bash
```
Start the simulation environment of limo, limo have two movement mode, the movement mode is Ackerman mode
```
roslaunch limo_gazebo_sim limo_ackerman.launch
```
Start rqt_robot_steering movement control plug-in, the sliding bar can control the robot motion
```
rosrun rqt_robot_steering rqt_robot_steering
```
![img](image/limo_ackerman.png)
Four-wheel differential steering movement mode
```
roslaunch limo_gazebo_sim limo_four_diff.launch
```
Control by keyboard, the robot can be controlled to move forward, left, right and backward through "i", "j", "l",and "," on the keyboard
```
rosrun teleop_twist_keyboard teleop_twist_keyboard.py
```

## Declare ROS messages, services and actions ##
################################################
## To declare and build messages, services or actions from within this
## package, follow these steps:
## * Let MSG_DEP_SET be the set of packages whose message types you use in
## your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
## * In the file package.xml:
## * add a build_depend tag for "message_generation"
## * add a build_depend and a exec_depend tag for each package in MSG_DEP_SET
## * If MSG_DEP_SET isn't empty the following dependency has been pulled in
## but can be declared for certainty nonetheless:
## * add a exec_depend tag for "message_runtime"
## * In this file (CMakeLists.txt):
## * add "message_generation" and every package in MSG_DEP_SET to
## find_package(catkin REQUIRED COMPONENTS ...)
## * add "message_runtime" and every package in MSG_DEP_SET to
## catkin_package(CATKIN_DEPENDS ...)
## * uncomment the add_*_files sections below as needed
## and list every .msg/.srv/.action file to be processed
## * uncomment the generate_messages entry below
## * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)
## Generate messages in the 'msg' folder
# add_message_files(
# FILES
# Message1.msg
# Message2.msg

## Declare ROS dynamic reconfigure parameters ##
################################################
## To declare and build dynamic reconfigure parameters within this
## package, follow these steps:
## * In the file package.xml:
## * add a build_depend and a exec_depend tag for "dynamic_reconfigure"
## * In this file (CMakeLists.txt):
## * add "dynamic_reconfigure" to
## find_package(catkin REQUIRED COMPONENTS ...)
## * uncomment the "generate_dynamic_reconfigure_options" section below
## and list every .cfg file to be processed
## Generate dynamic reconfigure parameters in the 'cfg' folder
# generate_dynamic_reconfigure_options(
# cfg/DynReconf1.cfg
# cfg/DynReconf2.cfg
# )
###################################
## catkin specific configuration ##
###################################
## The catkin_package macro generates cmake config files for your package
## Declare things to be passed to dependent projects
## INCLUDE_DIRS: uncomment this if your package contains header files
## LIBRARIES: libraries you create in this project that dependent projects also need
## CATKIN_DEPENDS: catkin_packages dependent projects also need
## DEPENDS: system dependencies of this project that dependent projects also need
catkin_package(
# INCLUDE_DIRS include
# LIBRARIES mycobot_description
# CATKIN_DEPENDS other_catkin_pkg
# DEPENDS system_lib
)
###########
## Build ##
###########
## Specify additional locations of header files
## Your package locations should be listed before other locations
include_directories(
# include
# ${catkin_INCLUDE_DIRS}
)
## Declare a C++ library
# add_library(${PROJECT_NAME}
# src/${PROJECT_NAME}/mycobot_description.cpp
# )
## Add cmake target dependencies of the library
## as an example, code may need to be generated before libraries
## either from message generation or dynamic reconfigure
# add_dependencies(${PROJECT_NAME} ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
## Declare a C++ executable
## With catkin_make all packages are built within a single CMake context
## The recommended prefix ensures that target names across packages don't collide
# add_executable(${PROJECT_NAME}_node src/mycobot_description_node.cpp)
## Rename C++ executable without prefix
## The above recommended prefix causes long target names, the following renames the
## target back to the shorter version for ease of user use
## e.g. "rosrun someones_pkg node" instead of "rosrun someones_pkg someones_pkg_node"
# set_target_properties(${PROJECT_NAME}_node PROPERTIES OUTPUT_NAME node PREFIX "")
## Add cmake target dependencies of the executable
## same as for the library above
# add_dependencies(${PROJECT_NAME}_node ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
## Specify libraries to link a library or executable target against
# target_link_libraries(${PROJECT_NAME}_node
# ${catkin_LIBRARIES}
# )
#############
## Install ##
#############
# all install targets should use catkin DESTINATION variables
# See http://ros.org/doc/api/catkin/html/adv_user_guide/variables.html
## Mark executable scripts (Python etc.) for installation
## in contrast to setup.py, you can choose the destination
# catkin_install_python(PROGRAMS
# scripts/my_python_script
# DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
# )
## Mark executables for installation
## See http://docs.ros.org/melodic/api/catkin/html/howto/format1/building_executables.html
# install(TARGETS ${PROJECT_NAME}_node
# RUNTIME DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
# )
## Mark libraries for installation
## See http://docs.ros.org/melodic/api/catkin/html/howto/format1/building_libraries.html
# install(TARGETS ${PROJECT_NAME}
# ARCHIVE DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
# LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
# RUNTIME DESTINATION ${CATKIN_GLOBAL_BIN_DESTINATION}
# )
## Mark cpp header files for installation
# install(DIRECTORY include/${PROJECT_NAME}/
# DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}
# FILES_MATCHING PATTERN "*.h"
# PATTERN ".svn" EXCLUDE
# )
## Mark other files for installation (e.g. launch and bag files, etc.)
# install(FILES
# # myfile1
# # myfile2
# DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION}
# )
#############
## Testing ##
#############
## Add gtest based cpp test target and link libraries
# catkin_add_gtest(${PROJECT_NAME}-test test/test_mycobot_description.cpp)
# if(TARGET ${PROJECT_NAME}-test)
# target_link_libraries(${PROJECT_NAME}-test ${PROJECT_NAME})
# endif()
## Add folders to be run by python nosetests
# catkin_add_nosetests(test)
