Hi, probably you hit over this issue. To verify this, please check the moveit's log and look for messages saying something ¨Orientation constraint violated ..."

If this is your problem, you need either to

a) modify moveit code as I did b) try this workaround

good luck!

btw, I improved turtlebot_arm greatly on indigo.... you cannot use it instead of hydro?

i have tried in indigo as well but facing same error. the issues you linked plans the path in some way but my arm does not plan any path at all, all it does with pick and place code is goes from home to rest pose

There are not turtlebot_arm hydro branch, so I understand you are running indigo devel code on hydro, right? Are you trying the running moveit demo? In emulation or with real robot (should not make any difference)

Running "roslaunch turtlebot_arm_moveit_config demo.launch" and then "rosrun turtlebot_arm_moveit_demos pick_and_place.py" works for me, so I need more details to reproduce the problem

When you start "roslaunch turtlebot_arm_moveit_config demo.launch" without arguments, it starts a "fake" arbotix controller that just mover the arm model on RViz, so you can run pick and place demo without a real robot. Of course this is not a simulation, but is an easy start.

That said, I can simulate the arm on Gazebo. LAunch and config files are here. But I would rather try to fix the planning problem just starting moveit with a "fake" arm, as explained in my previous comment

in my case, i dont have real arm at all, i have clone turtlebot arm from github and built is using catkin_make after resolving arbotix and dependencies and using the hydro version of moveit. even running the pick and place with demo.launch doesnot work. p.s. moveit pr2 tutorial codes runs fine
