Migrating from Rosbuild to Catkin can be accomplished using the ros-industrial catkinize script as described in Quickly migrating from Rosbuild to Catkin. Although this script attempts to replace rosbuild commands with catkin ones, some errors arise when compiling using the catkin_make command. This troubleshooting guide covers steps to take after catkinizing a package. Update messages…Read more Troubleshooting: Rosbuild to Catkin migration
Quickly migrating from Rosbuild to Catkin
ROS uses CMake, a powerful cross-platform build tool, at its core. Rosbuild and Catkin are ROS scripts for managing the CMake-based build system for ROS. Catkin is the newer, preferred option. ROS packages that are build using Rosbuild do not work in a Catkin workspace thus it becomes necessary to migrate from Rosbuild to Catkin.…Read more Quickly migrating from Rosbuild to Catkin
Setting up Vim for C++ development

Getting started quickly with Deep Learning
Machine learning is a fascinating field. Roboticists should invest the time and effort in understanding the fundamentals of machine learning. When it comes to deep learning, it's possible to get started quickly by using a library with pre-trained models. However, building your own models (however simple they might be in the beginning) is a great…Read more Getting started quickly with Deep Learning
How to host your website on GitHub Pages with a custom domain
If you have a simple website (some Javascript with CSS and HTML) and you're looking for a place to host it for free, GitHub is not a bad choice. You have the option of hosting without a custom domain (username.github.io/repository) or you can use your own custom domain (example.com). This guide assumes that your personal…Read more How to host your website on GitHub Pages with a custom domain
ROS performance testing: C++ vs Python
ROS supports both Python and C++ programming languages, however, using Python can come at a performance cost. I did an experiment to test this by writing four combinations of publisher to subscriber and then checking whether the real loop rate (of the publisher) is equal to the actual loop rate of the subscriber. The combinations…Read more ROS performance testing: C++ vs Python
