Level 5

So, turns out that the Charuco (chessboard + aruco) board I printed out to calibrate the OAK-D was too small. Maybe I should print it on an A3 sized sheet instead. But because of this drawback, I wasn’t able to proceed with my OAK-D tasks. I will go to the... [Read More]

Last week, I attended ROS World 2021, a virtual ROSCon, after this year’s event in the USA was cancelled. Like the actual ROSCon, ROSWorld is a three day (including workshops) event with multiple keynotes, panel discussions and talks about ROS/ROS2, a crazy amount of ROS based companies advertising their newest...

This week was all about getting the robot to move sideways using different local planners. In my last update, although I had not completely fine-tuned all move_base parameters, I was sufficiently happy about its initial performance. I used Base Local Planner plugin as a local planner, and despite trying everything,... [Read More]

I spent this week mostly learning about Behavior Trees, especially in robotics using ROS. A behavior tree is a structure that defines the different tasks of an agent and how to switch between them. Although this is a relatively new concept (for me, at least), its a familiar concept to... [Read More]

After the last update, I had a robot capable of performing SLAM, building 2D maps and localizing within a map using amcl. 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...
