安装arbotix simulator仿真环境（）

先安装rbx1功能包：

cd ~/catkin_ws/src
git clone https://github.com/pirobot/rbx1.git
cd rbx1
git checkout indigo-devel
cd ~/catkin_ws
catkin_make
source ~/catkin_ws/devel/setup.bash
rospack profile 

 安装模拟器：

sudo apt-get install ros-indigo-arbotix-*

删除早期版本的arbotix堆栈

rospack profile

一切成功后，先启动roscore，然后启动arbotix堆栈

roslaunch rbx1_bringup fake_turtlebot.launch

 使用一个模型的pi机器人，运行命令：

rosrun rviz rviz -d `rospack find rbx1_nav`/sim.rviz

 

发布消息，测试模拟，使模拟机器人顺时针旋转：

rostopic pub -r 10 /cmd_vel geometry_msgs/Twist '{linear: {x: 0, y: 0.2, z: 0}, angular: {x: 0, y: 0, z: 0.5}}'

需要停止机器人 ，在同一个终端窗口式Ctrl-C，或者发布空Twist message：

rostopic pub -1 /cmd_vel geometry_msgs/Twist '{}'
