2016-06-23 14:15:13 -0500 answered a question "startGrabbing: Node is not writable." in pylon_camera package

I reported the problem as suggested by @gvdhoorn

They promptly committed a bugfix:

All is well now after an update!

2016-06-20 19:28:33 -0500 asked a question "startGrabbing: Node is not writable." in pylon_camera package

Hi,

When I try to launch the pylon_camera node, I receive the following error:

startGrabbing: Node is not writable.

I traced through the code and found that an exception is thrown when the node is trying to set the PixelFormat to Mono8 using the setValue function in pylon_camera_base.hpp in the startGrabbing function.

I'm using the basler ace acA4600-7gc GigE camera with pylon 5 sdk. I can view the camera images and set camera parameters just fine using the PylonViewerApp.

Any advice?

Thanks, Michael

2013-03-13 13:34:01 -0500 asked a question stomp_motion_planner

Hi,

I recently cloned the STOMP git repo, and the code doesn't compile. I'm running Fuerte on 12.04.

The issues I'm having are when I try to compile stomp_motion_planner:

  • stomp_optimizer.cpp complains that StompCollisionSpace doesn't have a lock/unlock
  • /stomp_planner_node.cpp:129:83: error: no matching function for call to ‘stomp_motion_planner::StompCollisionSpace::init(planning_environment::PlanningMonitor*&, double&, std::string&)’
  • stomp_planner_node.cpp:224:26: error: ‘class stomp_motion_planner::StompCollisionSpace’ has no member named ‘setStartState’
  • stomp_planner_node.cpp:258:13: error: ‘class planning_environment::PlanningMonitor’ has no member named ‘prepareForValidityChecks’
  • stomp_planner_node.cpp:260:31: error: ‘struct arm_navigation_msgs::MotionPlanRequest_<std::allocator<void> >’ has no member named ‘ordered_collision_operations’
  • stomp_planner_node.cpp:261:31: error: ‘struct arm_navigation_msgs::MotionPlanRequest_<std::allocator<void> >’ has no member named ‘allowed_contacts’
  • stomp_planner_node.cpp:264:31: error: ‘struct arm_navigation_msgs::MotionPlanRequest_<std::allocator<void> >’ has no member named ‘link_padding’
  • stomp_planner_node.cpp:409:26: error: ‘class stomp_motion_planner::StompCollisionSpace’ has no member named ‘setStartState’

Any help would be appreciated.

Thanks, Michael

2013-01-10 08:20:08 -0500 answered a question Run Graspit! with plugin

Hey,

I couldn't get this working either. I looked through the source and it seems that there is a bug in the graspitGUI.cpp code for loading plugins on the command line. The problem is here starting at line 155 in graspitGUI.cpp:

//look for plugins of the form plugin:name in the arguments
for (int i=1; i<argc; i++) {
QString arg(argv[i]);
if (arg.section(',',0,0)=="plugin") {
  QString libName = arg.section(',',1,1);
  std::cout << "Processing arguments \n ";
  PluginCreator* creator = PluginCreator::loadFromLibrary(libName.toStdString());     
  if (creator) {
    mPluginCreators.push_back(creator);
  } else {
    DBGA("Failed to load plugin: " << libName.latin1());
  }
}

This shows that "if (arg.section(',',0,0)=="plugin")" and "QString libName = arg.section(',',1,1);" are actually looking for an argument of the form "plugin,name" versus "plugin:name"

So, just change your argument to "plugin,name" to get it to run for now I guess... Or, recompile with the commas replaced with colons.

2012-07-12 05:24:51 -0500 asked a question how to use interpolated_ik_motion_planner

Hi,

Does anyone have any examples or know of any documentation on using the interpolated_ik_motion_planner with the planning_scene_warehouse_viewer?

Thanks!

It looks like it may be possible just to use the pr2_arm_kinematics_node. I haven't tried it yet but it looks generic enough.

2012-06-21 14:12:24 -0500 asked a question planning_scene_warehouse_viewer crashes when using secondary IK

Hi,

I'm using ROS Industrial on Electric. Everything works except when I try to plan a new trajectory using the secondary planner (interpolated IK), planning_scene_warehouse_viewer crashes:

[planning_scene_warehouse_viewer-10] process has died [pid 3263, exit code -11].

I have tried it with the stock code from the repository with the sia10d:

$ roslaunch sia10d_mesh_arm_navigation planning_scene_warehouse_viewer_sia10d_mesh.launch

Any ideas?

Thanks, Michael
