2015-04-21 23:31:21 -0500 | commented answer | KUKA LBR iiwa real-time control Hi, I'm currently trying to use the first link, but I get stuck at running the Kuka Hardware Manager. It says "Assignment not possible while KS is running", do you guys have the same problem? If you're using the same thing, that is? |
2014-01-28 17:23:32 -0500 | marked best answer | Using multiple arduinos / running multiple nodes Hi, I have two arduinos (Uno and Duemilanove) and I want to use the two of them in parallel on one machine. However, rosserial_python does not accept multiple /dev files as parameters, so I cannot give the addresses of both arduinos to one rosserial_python node. The other option is running multiple rosserial_python nodes with each having different parameters, but ROS does not allow that since there are multiple nodes with the same name. It should be possible to run multiple nodes on one machine, but I don't know how. Any help is appreciated, thanks in advance! |
2014-01-28 17:23:30 -0500 | marked best answer | Creating models for household_objects_database Hi, I'm trying to add a new model in a local version of the household_object_database so I can recognize my own objects with the tabletop_object_detector. I made a model in Solidworks and exported it to STL format, which I exported again to PLY format using Blender. Then I deleted all models from my local database and used insert_model.cpp to add my own model and added it manually to a model set, the database seems fine now. The problem is, when I launch tabletop_complete.launch I get the following error: Everything works when I use the original models from the database, so I suspect that the model I made is faulty. Is there a better way to create models? I also tried 3DSom as described in the link below, but 3DSom is licensed and doesn't work properly for me. Are there any other ways to create 3D models? Thanks in advance! |
2014-01-28 17:23:27 -0500 | marked best answer | Run tabletop_collision_map_processing node Hi, does someone know how to run the tabletop_collision_map_processing_node from the tabletop_collision_map_processing package? I try to use the tabletop package to create collision maps and to detect objects for my own made robot, which uses a Kinect camera. The robot needs to detect objects and has to grab the object when it's near. This is what I've tried so far: When I do this, I get the following error: However, I don't know which node advertises this service.. Do I have to advertise this myself? image_processing is my own package, I imported the database from svn and the launch file looks like this: The yaml file looks like this: Thanks in advance! |

2013-10-18 12:56:47 -0500 | commented question | ld searches in wrong folder for libraries when cross-compiling Hi, sorry for the late reply, I just noticed this post.. I never succeeded in solving this problem, so I can' t help you with this unfortunately. I basically gave up on this, but mainly because of the switch from rosbuild to catkin, so it became rather useless for me to try this anymore. |

2013-03-01 13:02:01 -0500 | answered a question | How to use Fuzzy logic in ROS..? Hi, I use http://code.google.com/p/fuzzylite/ for my own project where I need to implement a fuzzy controller for collision avoidance. This library is fairly easy to use and only relies on STL, so it's also easy to install. See main.cpp in the src folder for a simple example on how it works. It's not specifically for ROS though, but ROS supports the use of third party libraries. Just link the library to your executable using target_link_libraries in the CMakelists of your project. As far as I know, there is no ROS package dedicated to fuzzy logic. |

2013-02-13 12:12:47 -0500 | asked a question | ld searches in wrong folder for libraries when cross-compiling Hi guys, I'm trying to cross-compile my own packages for armv7, so far I've been able to specify the correct toolchain by using the rostoolchain.cmake file. I also fixed a lot of other things I've had trouble with, but the only thing I'm having trouble with right now is specifying the correct folder for ld to search for libraries. I have stored all the ARM-compiled .so files I need in /opt/armv7/usr/lib, but ld still tries to look for libraries in /opt/ros/groovy/lib and /usr/lib. Since the files in those directories are compiled for Intel, that doesn't work of course. This is the error I get when I try to compile: How do I specify the correct folder for ld to look into? So far, I've tried the following "solutions" with no success:
I think I tried even more, but I forgot.. At least these are the most important things I tried. I'm stuck for weeks now so I'd really appreciate it if someone is able to help me. My rostoolchain.cmake file looks like this by the way: (more) |
2013-02-06 14:24:09 -0500 | commented answer | Creating models for household_objects_database I'm aware you're not talking about the roboearth website.. But as I tried to explain, the answer to your question is probably: No, the household_object_database cannot be used for RoboEarth, since RoboEarth probably uses another format for 3D models. |

2013-01-29 23:18:39 -0500 | commented answer | Creating models for household_objects_database Also, the models in the houdehold_object_database are in a different format than the models used for RoboEarth and the general structure of the database is different, so I don't think that you can use the household_object_database in combination with RoboEarth, at least not in a simple way. |
2013-01-29 23:15:56 -0500 | commented answer | Creating models for household_objects_database As far as I know, the household_object_database only works with the tabletop_object_detector. Roboearth has its own database and you can easily add your own models to it. Check out Roboearth's website or google it for more info, been a long time since I used it so I don't quite remember.. :P |
