Green, Affordable, High Accuracy Robot Drilling and Countersinking

TPR have developed a lightweight, low energy (green) robotic drilling system. Targeted for affordable automation of aerostructure small assemblies (hole sizes up to 10mm). It was successfully demonstrated at Technology Readiness Level (TRL6) – this being the highest level of acceptance outside of a manufacturing site. The testing was on the ATI (Aircraft Technology Institute) and Innovate UK grant funded “ADI: Automated Drilling and Inspection” project, with technical oversight from Airbus, BAE Systems, GKN Aerospace and FANUC UK.
