RPY Extractor

The rpy extractor online converts rotation representations to roll-pitch-yaw angles. It accepts a 3x3 rotation matrix, a quaternion (w, x, y, z), or an axis-angle pair, and outputs a single, consistent triple of Euler angles in your chosen units. It is designed for engineers, researchers, and students who need quick orientation interpretation without writing custom math.
Conceptually, inputs are validated and normalized, then converted to a rotation matrix and processed using the ZYX (roll around X, pitch around Y, yaw around Z) convention. Singularities near gimbal lock are detected and handled to provide stable, interpretable results. Output can be requested in radians or degrees, with a clear indicator of validity.
The tool's value lies in supporting multiple input representations in a single workflow, enforcing numeric validation, and offering flexible unit handling. It is well-suited for QA checks, robotics calibration, and simulation validation where consistent Euler angles are required for control and visualization pipelines. Typical use cases include robotics arm alignment, UAV attitude verification, and graphics orientation debugging. It avoids assumptions about time sequences and focuses strictly on a single orientation frame, delivering precise angles that can feed controllers, simulators, or data analyses.
