Foam-depth coverage & spot height
Real-time spot height and depth-coloured 2.5D mesh maps of the underfloor ceiling, so installers can prove applied foam meets BBA thickness standards before the robot leaves the void.
Problem
Spraying foam under a floor is only half the job. Installers have to show that the insulation meets the British Board of Agrément (BBA) thickness standard, in a void they cannot see into, and they need to know about thin patches while the robot is still in there to fix them.
What I did
I gave the spray robots the features needed to validate foam thickness: a real-time spot height measurement, and a depth-coloured mesh map of the underfloor ceiling. Together they let installers validate the applied foam thickness against the British Board of Agrément (BBA) insulation standards. For every coverage 3D scan an installer takes, the system generates a 2.5D mesh map from the input point cloud, colours it by foam depth, and overlays it on both the camera image and the 3D scan.
Result
Every coverage scan now produces a depth-coloured 2.5D map on the camera image and the 3D scan, so installers can validate applied foam thickness against BBA insulation standards and fix thin patches before the robot leaves the void. The video at the top was recorded in the MK6.3 test cell.
