"You should use that argument as an expert witness in a court!"

Yes, but then I'd have to be in a room with lawyers.

Junko, the part about 100% testing annoys me because as engineers, know that nothing is absolute. So, of course there's always a chance of something happeneing no matter how hard you work to prevent it. But lawyers try to explit even the tiniest of possbilities.

If I get get caught speeding, I might use my measurement knowledge by questioning the uncertainly of a radar gun's measurement. You see, all measurements have a tolerance, an accptable range where the actual value might fall. On top of that, there's a confidence level, some thing like. "You can be 95% confident that the actual measured speed was withing x% of the measured speed. But, that still means there's a 5% chance that the acual value is outside acceptable tolerance. It could be anywhere. Then you might ask when was the radar gun last calibrated? Perhaps it's past it's calibration interval period.

Junko,

So I'm thinking about my right thumb, fractured in 2009 when my car was hit from the right and the first joint smashed into the steering column. My hand was on the shift lever at the time of vehicle impact. I can't imagine how any kind of testing would have prevented that injury. But in the scheme of things, it's a very minor injury.

The result is that handwriting is difficult and I learned to use a trackball left handed. It drives the IT guys crazy when that have to take over my computer to install software.

"if the quality of a car does get better, that's a good thing."

Yes, of course. And I'm sure that there will be injuries that won't ever occur because of that testing, but how do you prove it?

Ha ha, i love your picturing a lawyer asking: "you can't 100% test for safety with a robots."

That's a good one.

But even if it is challenged in a court, if the quality of a car does get better, that's a good thing. That's a business risk you have to take as a company, I suppose.

I can see it now. A car is tested with robots and the tests are more accurate and repeatable and overall, cars get safer. But there will be one accident with a car tested with robots where the laywers will question the test methods and say "you can't 100% test for safety with a robots" Robots don't have injuries, people do?

Trouble is, no matter how well, you test with a robot, the results will be challeneged in courst wooner or later.

I am with Dylan on this. I thought this has been done for years.

But I think those robots will never replace human test drivers. They will only complement them like computer simulations. By the way, I would miss all these brand new cars on our streets. Just two days ago I believe I have seen a prototype of the new Mercedes GLA.

Using the robots for testing a vehicle is definitely makes it faster and more accurate. This is basically automated regression test for the automobile on test track. It definitely involves huge understanding of the stresses or impact and in the end it requires the engineers to track the data from the tests.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
