安装arbotix simulator仿真环境--9

原创博客：转载请表明出处：http://www.cnblogs.com/zxouxuewei/  周学伟

安装之前：首先确保已经正常制作了ros工作空间并且安装了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 

1.安装simulator

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

注意：一定要删除任何早期版本的arbotix依赖。

rospack profile

2. 为了确保一切工作，确保roscore运行，然后启动模拟turtlebot如下

roslaunch rbx1_bringup fake_turtlebot.launch
输出信息如下：

4.接下来，把rviz所以我们可以观察模拟机器人在行动：

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

5.发布消息，使机器人移动。要测试模拟，打开另一个终端窗口，并运行以下要使模拟机器人在逆时针方向移动：

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

6.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 - /cmd_vel geometry_msgs/Twist '{}'
