Turtlebot2, Groovy, turtlebot_arm-groovy-devel package:

After roslaunching turtlebot_arm_bringup simple_arm_server.launch:

[simple_arm_server.launch] is neither a launch file in package [turtlebot_arm_bringup] nor is [turtlebot_arm_bringup] a launch file name

Can anyone tell me how to fix it? Thanks so much!

Hi, @Yantian_Zha : There are arm.launch and fake-arm.launch in /turtlebot_arm_bringup/launch . There is not the simple_arm_server.launch you say. The simple_arm_server packages seem to be put on this page ( ). If you want to execute it, I think that you should type

roslaunch simple_arm_server arm_server.launch

You will get more useful information on than one on Please check it out!

With Groovy and later, the arm_navigation package became deprecated in favor of MoveIt. As part of that, simple_arm_server (which leveraged portions of arm_navigation) became deprecated. I never did get around to releasing all of turtlebot_arm under MoveIt, but the start of it is in the groovy-devel branch of .

Specifically, I did create an FastIK plugin which negated the need for the simple_arm_server, however, since that was checked in the API on the KinematicsBase class has changed, and so the package may need updates in order to compile with the latest versions of MoveIt!

So, can I use the old version of Moveit! in order to use your turtlebot_arm package? And if I can, which version should I get? Thanks!

And also a question: there is arm_navigation groovy devel, so I guess simple_arm_server can still be used?

Fergs,in block_detection_action_server.cpp you construct a client by simple_arm_server(line57),and I didn't found any function using IKFast plugin.I'm confused in your understanding in this cpp is that this server accepts a goal,processes it,and sends(as a client) to simple_arm_server
