This month I received a sample X2 LiDAR from YDLIDAR. In this blog post I’m documenting my experience using it and using it for SLAM using ROS and Google Cartographer.
It has been one year since I decided to go solo and start working as a Robotics consultant/contractor. In this post I’ll sum up my experience so far.
Continuing on my excursion in LiDAR testing I gave a Livox Mid-40 a spin. This post sums up my experience working with it for couple of days.
By default ROS doesn’t indicate what is the state of a particular node. If a node exits abnormally (for example when an exception is raised, or a computer running the node is power cycled) ROS master will still hold a reference to this node. Fortunately there are some tools that can help you check/clean the node status.
