这是moveit_simple_grasps对ubuntu14.04的兼容问题
参考：
qboticslabs/mastering_ros#3

@qboticslabs
I have found two solutions for this problem. This problem can vary in different system with different environment.

Possible solution:

1. Stick on to Ubuntu 14.04.2 instead of Ubuntu 14.04.3. The package will perfectly work in ROS version 1.11.13. I think you will get this version in Ubuntu 14.04.2
2. If you are using Ubuntu 14.04.3, take a try with the following package

https://github.com/qboticslabs/mastering_ros/blob/master/chapter_10_codes/moveit_simple_grasps_1.zip
Please get back to me with your issues to my mail id : qboticslabs@gmail.com.
I am not closing the issue now, waiting for your response !!!

看来要研究下怎么修改它，让它能在ubuntu14.04.5上用……

I'm using ubuntu 16.04 . Which package should I use? @yao62995 @cookiegg

@cookiegg
Hello,
I meet same problem. 現在可以在14.04.5下使用嗎？

[cookiegg]

我之后没有尝试了。现在在做其他方向。很抱歉没能解决你的问题。 2017-04-07 14:32 GMT+08:00 WeJay <notifications@github.com>:

I have the same problem in Ubuntu16.04 ROS Kinetic.
Have you solve the problem?

想问一下， moveit_simple_grasps对ubuntu14.04.5的兼容问题解决了吗？谢谢 @cookiegg @kottesaikumar @WeJay @wangcongrobot

现在我是采用openai gym,抓取规划可以试试graspit!

你好，想问一下，这个as_6dof_arm，你最后调试出来了嘛？谢谢 | | Bary Wang 邮箱：iamwhtwd@163.com | 签名由 网易邮箱大师 定制 在2018年01月13日 23:13，cookiegg 写道： 现在我是采用openai gym,抓取规划可以试试graspit! — You are receiving this because you commented. Reply to this email directly, view it on GitHub, or mute the thread.
