2023-07-24 02:58:52 -0500 | marked best answer | [ROS2] Best Practices: /rosout versus /diagnostics I want to monitor the status of my different ROS2 nodes and act accordingly if something happens. Some of these nodes are hardware drivers, while others are not, working on things such as image processing, data upload, etc. One way of monitoring the status is to subscribe to Another approach that i am entertaining is to use the diagnostics system to monitor status. From the ROS wiki I quote:
Furthermore when looking at the message definition that both use, DiagnosticStatus and Log, their definitions seem very similar. Considering the above information, I find it difficult to determine which to use. This has lead to two questions:

I have found the following question from a while ago: https://answers.ros.org/question/3073... but maybe there is an easier solution available now. |

2022-09-19 17:51:34 -0500 | marked best answer | Inverse Dynamic library implementation in ROS? I want to use Inverse Dynamics to implement a hybrid Torque/Position on an exoskeleton. My intitial plan is to use a detailed URDF of my robot and then a software tool that can take it and solve for the torque that needs to be generated by a joint to follow the path. The system will have to run on ubuntu 16.04.5 LTS with ROS kinetic I found a large list of different solvers that can be used, found here I have focussed my search on the following four solvers:
It seems that all of these methods do pretty much the same thing. Which of the inverse dynamics solver is best supported by ROS? What solver is generally used by ROS users? What are important aspects to take into account when choosing a solver? |

Catch and except rclpy.spinoriginal post code update post code after @Geoff comment Create a custom logger in launch filefrom the example launch found here, a custom event handler can be created.
