2018-09-19 17:22:08 -0500 | marked best answer | How to move TurtleBot in gazebo 7 Hello, I am trying to simulate at TurtleBot in Gazebo 7 (with Kinetic Kame), however I am having sending a velocity to the simulated robot. I was able to fix the xacro files to properly create a URDF that Kinetic Kame liked, and I am also able to receive the Kinect data. However, I am unable to send velocity commands from the nodelet to Gazebo. Looking into the Gazebo 7 documentation, I noticed that I am expected to use Are controllers used in Indigo? If so, where can I find them to modify them? Am I approaching this wrong? If so, how should I fix this? |

2017-07-06 22:27:39 -0500 | marked best answer | Having trouble with custom nodelets Hello, I am starting to use nodelets in my image processing pipeline, and I am having trouble loading nodelets. I am using the freenect_stack package as a sample to get started. Whether I use the nodelet loader in c++, a launch file, or command line arguments, the loader refuses to create the nodelets. I am using ROS Hydro, that I compiled from source on Ubuntu 14.04.2 LTS. I would appreciate any help or troubleshooting steps. Thanks, Daniel This is the error, whether I use the command line, roslaunch, or the loader library in c++. The command line and roslaunch also say "service call failed":
This is the exported face_provider.xml file. If I look under the ~/catkin_ws/devel/lib directory, I find the "libface_provider_nodelets.so" file, and inspecting it shows that there that looks like it loads my nodelets. This is the code I am using to load the plugins: My pluginlib macros look like this: and EDIT: So I am going back and rewriting this from scratch (as opposed to copying code from my nodes), and I notice that once I include the opencv, imagetransport, and cv_bridge headers, the problem arises. The error code was different, complaining that it couldn't find the library path using some_path/lib//libface_provider_nodelets. Changing my face_provider.xml file changes to "liblibface_provider_nodelets" gives me the familiar "Failed to load nodelet error" EDIT2: So I backtracked a bit, and took most of the the openCV code out. However, whenever I include the header for the nodelet where I have opencv code, I get (more) |

2017-05-27 07:54:05 -0500 | marked best answer | Having trouble using CUDA enabled OpenCV with kinetic Hello everyone. I started a new install of ROS Kinetic, and I was hoping to use a few CUDA features from OpenCV. I have successfully compiled and tested CUDA and OpenCV (which is installed in /usr/local), but I am having trouble using my OpenCV instead of the I have tried adding /usr/local to the front of my CMAKE_PREFIX_PATH, as well renaming the opencv pkgconfig file in /opt/ros/lib/pkconfig. However I still get the below error, indicating that I am building against the ROS OpenCv.
Any ideas? |
