2017-01-04 06:29:36 -0500 | asked a question | can't locate node [moveit_setup_assistant] in package [moveit_setup_assistant] Because the moveit is updated recently.So I use "sudo apt-get remove ros-indigo-moveit" to remove moveit.And then I used "sudo apt-get install ros-indigo-moveit" to reinstall moveit.It can be found in http://moveit.ros.org/install/ . After that I open a new terminal. I can rospack find moveit_setup_assistant in opt/ros/indigo/share. But when I run “roslaunch moveit_setup_assistant setup_assistant.launch” It appeared error After I run " I must source /opt/ros/indigo/setup.bash can I use moveit_setup_assistant.However, after source /opt/...,I can't rospack find the packages in catkin_ws.So after source /opt/...When I run I must source The bottom lines of my ~/.bashrc file is When I add the source /opt/ros/indigo/setup.bash to the last line,It also can't work.

2017-01-03 06:52:55 -0500 | commented answer | Unable to locate package ros-indigo-moveit-full Thanks a lot.I will wait for it. I am hurry to use moveit to control real UR5.The universal robot pkg needs moveit_kinematics. |

2017-01-03 04:38:27 -0500 | commented answer | Unable to locate package ros-indigo-moveit-full I have done "rosdep update and sudo apt-get update".as said here. And created an workspace named "ws_moveit".Then I can use move_group.launch But when I run a moveit_ik demo,it said "AttributeError: 'module' object has no attribute 'MoveGroupInterface'". |

2016-12-27 01:23:28 -0500 | asked a question | Using universal_robot pkg and moveIt to control real UR5 robot.UR5 can move but can't move to the desired pose.It saied "time exceeded and current robot state not at goal, last point required" When I use Universal_robot pkg and moveIt to control real UR5. The UR5 can't move to the desired pose.It stopped at a pose which is belong to the trajectory.My steps of operation are as follows 1."roslaunch ur_bringup ur_bringup.launch robot_ip:=192.168.1.160"which appears the connection is correct."The action server for this driver has been started" 2.Launch my moveit config file"roslaunch ur5_moveit_config_myself move_group.launch".The config file is generated by moveit_setup_assistant.and I add controller.yaml and ur5_moveit_controller_manager.launch.xml 3."rosrun rviz rviz" 4."rosrun le_node moveit_ik_demo.py" The file moveit_ik_demo.py is shown below. After I run the moceit_ik_demo.py. The UR5 begins to move toward the desired pose.But it came to a sudden stop in the journey .and can't attach to the desired pose. In the first terminal(launching the ur_bringup.launch),it appead that "[WARN] [WallTime: 1482755354.085866] Trajectory time exceeded and current robot state not at goal, last point required [WARN] [WallTime: 1482755354.086135] Current trajectory time: 1.92857694626, last point time: 1.913815417 [WARN] [WallTime: 1482755354.086456] Desired: [1.5887987717921845, -0.0001816342668607831, 0.0009067557118833066, -0.0009527113572694361, -0.0007133560068905353, -4.268342442810536e-05] actual: [1.6035473346710205, -0.6335380713092249, 0.2663407325744629, -0.233499828969137, -0.04164582887758428, -0.24181014696230108] velocity: [-0.003962783608585596, 0.1539221853017807, -0.06261198222637177, 0.06792659312486649, 0.009731191210448742, 0.060160811990499496] [2016-12-26 20:29:15.983806] Out: Braking" Maybe the reason is the time of the trajectory is limited. and I tried many times with the same peogram (the desired pose is different).The trajectory time is no more than 3 seconds. But I don't konw how to modify the limit of trajectory time.
