Software: quaternion converter tool

In my work as robotics engineer I frequently encounter orientations represented as quaternions. While quaternions offer advantages such as avoiding gimbal lock, I find it quite difficult to have an intuitive understanding of a rotation expressed in quaternion form. Although the conversion from quaternions to the more intuitive Euler angles can be easily implemented in a few lines of code, having a small GTK-based GUI tool for a quick conversion of quaternion values encountered in ROS topics or log files can be advantageous.

Note: The tool accepts arbitrary quaternion values and normalizes them to unit length before converting to Euler angles.

How-to install

Here’s how to download and install our Linux-exclusive tool for converting quaternions to Euler angles:
