Automated Optimisation of Robotic Scan Paths for Advanced NDT Inspection

BACKGROUND
The Centre for Ultrasonic Engineering at the University of Strathclyde in Glasgow and TWI are seeking a top class candidate to undertake research leading to a PhD awarded by the University of Strathclyde.

The project will require occasional travel on a short-term basis within the UK and overseas. A Baseline Personnel Security Standard (BPSS) organised by TWI must be achieved under the condition of this job offer.

PROJECT OUTLINE
Previous collaborative work undertaken by TWI and Strathclyde University has led to significant advances in the development of automated inspection using 6 axis robotic arms. Industry has indicated that significant cost benefits can be achieved through the integration of metrology, NDT and other activities within a single cell.

Currently robotic paths for inspection are generated offline using a CAD model of the part. The accuracy of the inspection is based on the assumption that the CAD file accurately represents the part being inspected, but parts frequently vary from design due to manufacture (e.g. spring-back from mould). This research will investigate methods of automating robotic path optimisation for advanced NDT inspections. It will include automated path generation for rapid laser profiling of parts, development of automated calibration routines to ensure continuous correction of end effector alignment and the use of photogrammetry and other systems to enable real time tracking and synchronisation of cooperating robots.

ABOUT UNIVERSITY/DEPARTMENT
The Centre for Ultrasonic Engineering (CUE) at the University of Strathclyde has embarked upon a bold investment aimed at creating the most comprehensive and capable ultrasonic and robotic Non-Destructive Evaluation (NDE) facility anywhere in the world. CUE includes one of the worlds’ leading research groups dedicated to ultrasonic evaluation and robotic inspection.
