Makes sense now thanks gentlemen

Hi all,

I have a question about how nodes are implemented in ROS. From what I understand the "type=" definition refers to an executable file that ROS runs. Consider this example:

<node name="robot_state" pkg="robot_state_publisher" type="robot_state_publisher"/>

Now when I go into the robot_state package I don't find an executable called robot_state_publisher. Would anyone care to explain why that is?

here is the link to the tutorial husky navigation

Hi,

when I run the husky navigation tutorial with Gazebo, Rviz and the husky navigation launch files I get the folllowing errors:

in Gazebo terminal: [ekf_localization-6] process has died [pid 24421, exit code -11, cmd /opt/ros/indigo/lib/robot_localization/ekf_localization_node __name:=ekf_localization __log:=/home/ros-industrial/.ros/log/bf37a29e-78c2-11e5-8ea8-080027b2b50d/ekf_localization-6.log]. log file: /home/ros-industrial/.ros/log/bf37a29e-78c2-11e5-8ea8-080027b2b50d/ekf_localization-6*.log

and

WARN] [WallTime: 1445521648.055750] [1472.830000] Controller Spawner couldn't reach controller_manager to take down controllers. Waited for 3 second(s).

in Rviz terminal: in move_base.launch terminal: The result is a robot that does not move in neither Rviz or Gazebo. If anyone could shed light on this problem that would be greatly appreciated.

Thanks, a quick search on the mailing list and I found the link to the cartesian path planner

Hi,

I have a custom moveit Rviz Fanuc 100ib arm simulation running and now I want to attach a tool and run a simulation where the tool moves along a path on an imported object. I'm not sure how I can accurately do this in multiple motions or by running nodes (executable C++ files). Right now I'm only able to move the robot arm from one position to another (start and goal point query) in the simulation. I've tried using echo rostopic joint_states to see the joint positions as I move the arm in Rviz but the joint positions remain the same in the terminal remain the same. Does anyone have any ideas on the best way to generate a tool-path using Moveit! and Rviz?

Regards, Devin

Everything work now, with your advice I was able to solve the problem. Thanks

Hi,

I haven't been able to get through to Fanuc about this concern I have and I am wondering how a machine running ROS is typically connected to an industrial robot controller? I have an R-30ib with me and there are connections to a RS-323C port and a PCMCIA connection port as well. I'm not sure which adapter I should buy to initiate communication between my laptop and the controller. Initially I was looking for an ethernet connection but I couldn't find one on the panel, if anyone has ever had experience with using ROS on industrial robot arms could give me some advice it would be greatly appreciated.

Regards, Devin

Great this is all very helpful I will not try all of it today since I've been using the Fanuc m16ib files as a replacement for my simulation, thank you very much and if there are any problems within the next few days I will add another comment

here is the imgur link to the photos: link text and here is the github link to the URDF: link text

take a look and tell me what you think. Thanks in Advance

I've attached a few pictures highlighting my problem and what is going on is I setup my axis and co ordinate systems in solidworks according to the guides whereby the axis are along the joints of the robot and the co ordinate systems for each joint is along the axis.

I export my URDF file from solidworks and when I create a moveit! package the joints are all misaligned and the motion is completely off. what I mean is the joints rotate at offset axis and the links are very far from one another. I've already varied the directions of the co ordinates but have seen the same results and I've managed to get the motion close to what it is supposed to be like but even so it's not what the motion should be like on the real robot.

I can't upload the files because I'm a very new member but hopefully one of the members here can still offer some advice.

thanks in advance

Okay and I did use a moveit based tutorial when creating my own moveit! package based on a URDF I exported from solidworks and received the same message when attempting to launch the launch files that were created. Any thoughts on that particular situation that doesn't involve a tutorial?

I am using Ros Industrial in Hydro and when attempting to launch files for the industrial arms in moveit! within the supplementary folder I receive this error message in my terminal:

raise ResourceNotFound(name, ros_paths=self._ros_paths) ResourceNotFound: m10ia_arm_navigation ROS path [0]=/opt/ros/groovy/share/ros ROS path [1]=/opt/ros/groovy/share ROS path [2]=/opt/ros/groovy/stacks

Has anyone ever seen messages like this before or have a solution? Thanks in advance

Hello all,

I am using ROS-Industrial Training and I'm receiving these messages when attempting to launch the supplementary launch files:

raise ResourceNotFound(name, ros_paths=self._ros_paths)
ResourceNotFound: irb_2400_arm_navigation
ROS path [0]=/opt/ros/hydro/share/ros
ROS path [1]=/opt/ros/hydro/share
ROS path [2]=/opt/ros/hydro/stacks

I was previously using Groovy and never had this problem, if anyone could shed some light on this problem it would be greatly appreciated.
