前言

在ROS学习与开发中，难免遇到各种各样的问题，除了一些可以解决问题（语法问题）外，其他一些问题有时很难发现并解决，在这里，总结下在开发中遇到的各种问题，不定期更新中。。。

为了方便和管理，每一个标题都是一些问题模块，现在有catkin_make编译模块。

catkin_make问题

问题1：在使用catkin_make过程中，明明有需要编译的包，但是系统提示找不到该路径，具体输出如下：

Traceback (most recent call last):
  File "/opt/ros/indigo/share/genjava/cmake/../../../lib/genjava/genjava_gradle_project.py", line 14, in <module>
    genjava.main(sys.argv)
  File "/opt/ros/indigo/lib/python2.7/dist-packages/genjava/genjava_main.py", line 82, in main
    gradle_project.create(args.package, args.output_dir)
  File "/opt/ros/indigo/lib/python2.7/dist-packages/genjava/gradle_project.py", line 152, in create
    raise IOError("could not find %s on the ros package path" % msg_pkg_name)

  File "/opt/ros/indigo/lib/python2.7/dist-packages/genjava/genjava_main.py", line 82, in main

  File "/opt/ros/indigo/lib/python2.7/dist-packages/genjava/gradle_project.py", line 152, in create
    raise IOError("could not find %s on the ros package path" % msg_pkg_name)
IOError: could not find turtlebot2i_marker_manipulation on the ros package path

IOError: could not find turtlebot2i_marker_manipulation on the ros package path.

解决方案： 下载genjava就可以正常编译。原因不明。命令如下：

$ sudo apt-get remove ros-indigo-genjava

Moveit! 问题

问题1： 当运行

roslaunch moveit_setup_assistant setup_assistant.launch

选择模型加载时，会突然系统崩溃。提示如下信息：

[rospack] Error: no package given
[librospack]: error while executing command

说明：

  1. 单独加载模型没问题.

  2. 使用moveit_setup加载其他模型有的没问题（例如，Turtlebot）。

  3. 只是使用有些模型会出现突然崩溃的情况。

解决方案：

方式1：检查模型中模型的属性，里面的是否加载的是.dae或.stl文件，如果有，将.dae或.stl替换成urdf本身自有的属性，例如，等。 举例：将

      <collision>
        <origin xyz="0.0 0.0 0.0" rpy="0 0 0"/>
        <geometry>
          <mesh filename="package://turtlebot2i_description/meshes/sensors/sr300.stl" scale="2.0 2.0 2.0" />
        </geometry>
      </collision>

替换成

      <collision>
        <origin xyz="0 0 0" rpy="0 0 0"/>
        <geometry>
          <cylinder length="0.006" radius="0.170"/>
        </geometry>
      </collision>

方式2：测试了下moveit_setup_assistant，发现模型加载mesh时，会出错，方式1是将现有属性替换，另外一种方式是改变自己制作的dae或stl文件名，不清楚什么原因，moveit_setup_assistant加载dae或stl时，模型名必须为小写，如果有大写出现就会报错，例如将Test_Finger.dae修改为test_finger.dae就不会造成崩溃。

方式3：如果是在加载别人做的dae或stl文件时，需要将dae或stl文件重写，我使用的是blender，将stl重新导出stl就不会造成崩溃。其他3D建模也可以尝试下，3D Max，solidworks，inventor等等。

其他解决方案如果有请告知。

ROS_Control + Gazebo问题

问题1：使用ros_control为模型添加Gazebo接口时，模型单独显示没有问题，在Gazebo中添加会错误，从而导致加载不了ros_control接口，报错如下：

解决：该问题原因是ros_control接口更新，有的旧的会不兼容，通过给选项添加标签，这个错误会消失，比如，在rrbot.xacro文件中，改变：

<joint name="joint1"/>

为：

<transmission name="tran1">
  <type>transmission_interface/SimpleTransmission</type>
  <joint name="joint1">
    <hardwareInterface>EffortJointInterface</hardwareInterface>
  </joint>
</transmission>
