2d SLAM with ROS and Kinect
Introduction So far we really did not tap much into the power of ROS. Teleoperation and dead reckoning was just a way to ‘warm up’ and get familiar with the basics of ROS. This is about to change as we...
View ArticleUsing the ROS Navigation Stack
In this post I cover how we can leverage the ROS navigation stack to let the robot autonomously drive from a given location in a map to a defined goal. I will skim over many of the details since the...

Ardros – Transform Between base_link and the Kinect Sensor
For SLAM and navigation to work correctly on a ROS based robot it is necessary to accurately specify the transformation between the coordinate system (frame) of the steering center of the robot (the...
