Ultrasonic Robotic Quality Control
of Fold Glue Joints by an industrial robot


Solution under Development

The FRS URQC-100 is a fenced robot cell which automates the highly sensitive ultrasonic quality measurements of fold glue joints of automotive closure panels.

This product revolutionizes today’s complex manual ultrasonic quality control, which is time consuming and error prone.

Automated, Robust, Fast & Flexible

In the past it has been difficult to robotically position an ultrasonic probe to measure a fold glue joint, because of small variances in the best position to get the optimal ultrasound signal.

FRS uses adaptive control based on both force sensor feedback and the ultrasound sensor feedback to guide the robot to the optimum position to make a measurement.
