BONNIE III - Non-Contact Nuclear Boiler Inspection
In 1988 Ontario Hydro mounted ultrasound transducers on the 'fingers' of a robotic arm. The disk from a nuclear reactor's boiler was rotated, and the quality of the surface of the boiler was determined by a custom signal processing system. I reported to David Hutchins, who co-authored an IEEE paper on the inspection technique.
I was contracted to write the display software using a programmable Pepper Pro video board. This gave us the ultimate in speed, since the video card's processor was more powerful than the 80386 used in the Compaq. The language I used was C.
Here are some pictures we took at the end of the project.
You can see the three giant fingers of the robot arm gripping the boiler disk:
This is a closeup of the robotic hand around the disk:
This is what the hand looked like all by itself:
Here is a view of the console, manned by an Ontario Hydro employee:
Three-dimensional images were returned by the ultrasound transducers. I programmed a customizable palette so surface defects could be observed easily. The images could be zoomed in and out:
This shows the same image at a higher magnification:
Still the same image at a higher magnification:
I provided the ability to view the data in black and white:
