wPOS - A 6 degree of freedom workpiece position and orientation sensor

Using lasers to measure position
Default image

The project aims to develop novel optical instrumentation, combining two complimentary optical measurements techniques, range-resolved interferometry and laser speckle pattern correlation. The resulting sensor wPOS (workpiece Position and Orientation Sensor) will be capable of remote, high quality and high-bandwidth measurements of the relative motion and orientation between a robotic end-effector mounted sensor and the workpiece. The sensors developed during the project will be applied to the WAAM process for the measurement, calibration and verification of robot paths.

Part of an EPSRC-funded project.
