执行 roslaunch smart_car myrobot.launch
出现:
RLException: [/home/milk/DEMO05_WS/src/smart_car/launch/myrobot.launch]
The traceback for the exception was written to the log file
model是什么,为什么网上搜不到这个错误
.launch:
<?xml version="1.0"?>
<launch>
<arg name="model"/>
<arg name="gui" default="False"/>
<param name="robot_description" textfile="$(arg model)"/>
<para name="use_gui" value="$(arg gui)"/>
<node name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher"/>
<node name="robot_state_publisher" pkg="robot_state_publisher" type="robot_state_publisher"/>
</launch>
我改成 roslaunch smart_car myrobot.launch model:="../urdf/myrobot.urdf"
现在又显示出IOError: [Errno 2] No such file or directory: u'../urdf/myrobot.urdf'
明明有那个文件,怎么找不到呢
