想使用arbotix节点时（代码如下）  

  <node name="arbotix" pkg="arbotix_python" type="arbotix_driver" output="screen">
        <rosparam file="$(find vehicle_description)/config/vehicle_control.yaml" command="load" />
        <param name="sim" value="true"/>
    </node>

出现如下错误：

[arbotix-4] process has died [pid 6242, exit code 1, cmd /home/sx/catkin_ws/src/arbotix_ros/arbotix_python/bin/arbotix_driver __name:=arbotix __log:=/home/sx/.ros/log/c4052c8a-6095-11ec-919e-000c292ea602/arbotix-4.log].
