Mr. Lake, what industrial controls did you use for the flexible test stands?

The automation of such a gigantic mechanism seems like a strenuous task. Good job and thanks for the informative blog post.

The old system didn't have much thought...

I would have thought that the old system would have, at the least , had test pallets where the device under test could have been loaded, off the test stand, and then put on the test stand and the test stand connections quickly made.

 

It sounds like the original stands were made to maximize cost at the expense of efficientcy.

Thanks for the interest and question. RedViking has developed a test stand control and software platform called RedRaven that incorporates a supervisory host system, PLC based machine function and safety control, high performance drive control, and integrated high speed data acquisition. The manufacturers of the hardware can very but in this case we integrated Rockwell AB PLCs, NI data acquisition hardware, and Siemens drives and Motor. The host system, which includes the HMI software, is all custom LabVIEW code.

My guess is that the original collection of test stands was created as each different type of helicopter was designed, probably by the first builders of each model. It often happens that way. And so there is a collection of test stands, each representing a different approach to different requirements and built over a span of many years. Designing a different stand to test all of the models with a different set of requirements is a great idea, but it is quite different from what the first projects were. And as system requirements change a lot, the original systems are not able to meet the new requirements. Not bad engineering, just "long ago and different specifications" engineering. Change will bury us if we aren't careful.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
