2021-06-28 20:29:48 -0500 | marked best answer | catkin_make unable to find actionlib in its original install location It seems as though it is looking for actionlib in one of our catkin workspaces. It was installed to /opt/ros/kinetic/share/actionlib. Is there a way to correct how catkin finds it? Is there another issue causing this? Edit: There are two workspaces. I'm working in workspace 2, I removed catkin_ws and now ws 2 makes fine. My new question is why did this happen to begin with? |

2020-10-22 12:54:32 -0500 | marked best answer | How does one assign values to messages with arrays in C++ This is probably more C++ focused, but here is my issue: The resulting error is: Now in python something like this would be an issue. In the past I have been using memcpy to get around this, but I am less certain that that is the approach to take for this. How can I add array data to a message with an array. |

2020-10-17 17:38:35 -0500 | marked best answer | Custom Message with uint8[] Reads as string dtype I'm trying to pass a custom message through a service . I have a C++ node using this service just fine, however in Python I can't seem to pull information from the custom message. When I try to take the passed array, it reads it as a 'str' type. Is there anything I am doing wrong here? Edit: in Visual Studio Code, when I create a variable field = DensityField() and type "field.data", hovering over "data" reveals that it thinks its a string. Is it possible to force catkin_make to regenerate the messages? I have no idea why it thinks its a string. GetDensity.srv: DensityField.msg: Service Client: The server: |
2020-10-17 17:38:31 -0500 | commented answer | Custom Message with uint8[] Reads as string dtype I guess that's on me for assuming it works similar to C++. I see that numpy is needed in this situation. |

2020-09-19 18:16:14 -0500 | marked best answer | Physical Multirobot AMCL Not Able To Transform To /map I'm trying to get multiple physical Turtlebot3's functioning with AMCL with namespaces. My setup works perfectly fine with the Gazebo simulations, but moving it to the real thing causes issues. After running AMCL I get the error: I have looked at the solution found here: https://answers.ros.org/question/3259... But I couldn't seem to see what I am doing wrong. There was also another source that I found here: https://github.com/wachlinn/mrc_hw8/b... but this seemed to have the same setup that I had. My steps are as follows:
