This weekend, I continued further and implemented the move_base package to complete the ROS navigation stack. Before I did that, I was exploring the navigation_experimental package and found...

This week, as planned, I tried out Steven Macenski’s slam_toolbox package alongside slam_karto, the ROS wrapper for the Karto mapping library, another popular SLAM method. Before I began, I reorganized the project directory structure to resemble that of the Turtlebot3 repo by Robotis, which makes things easier as it separates... [Read More]

I’ve been on holiday this week, and decided to have a staycation and spare some time working on the AKROS holonomic platform. I got it back from the friend I lent it to, wired it up, tested it and assembled with the navigation module. I am not using the encoders... [Read More]
