Self-Assembled Devices May Transform Manufacturing
4/3/2013

The 3D brick approach to self-assembly at the nanoscale is based on short synthetic strands of DNA that form building blocks, which self-assemble into 100 different, precise 3D shapes such as letters and numbers. Like the models of 80 of these shapes shown here, each unique shape measures about 25 nm per side.

Rob, I think you're right about those two apps. Meanwhile, though, people in machine vision and other industries have told me, off record, they wish they had robots, not humans, working in their factories.

Companies rarely invest in more workers when they make more profits--that would generally be seen as anti-productive, since the productivity metric is usually how many dollars are brought in per worker. Unless, of course, they've decided to expand operations that need more workers. And obviously this all depends on what kind of jobs and workers we mean. But many, many companies don't want more or any human workers: they want robot workers, automated hardware, and increasingly sophisticated software. Which makes me wonder how many engineering jobs have been lost to design software--anyone know?

Hey GTOlover,

If the robots are to coninue their expansion, it will be at the cost of blue collar jobs. That's the ROI. The addition of smart jobs must be small in comparison to the elimination of worker jobs or the robots will not offer value. Look out China.

Yes, Ann, and it will be interesting to see the future of robots. Apparently they are paying for themselves, since implementations dont get very far in factory automation without a clear ROI. It will be interesting to see who implements the new wave of robots. I'll put my money on the suppliers in auto and aerospace.

As fantastic as this is, I would like to see this tech integrated into robotic toys. True "transformers," a childhood dream is almost fulfilled.

Thanks, GTOlover. That's the point I was trying to make: what happens when low-skilled jobs are replaced by higher-skilled jobs? This sounds great--until you wonder what happens to the displaced workers. Once upon a time, there were a lot more low-skilled workers than high-skilled ones. I'd like to know what the proportions are today, in the US and elsewhere. The raw numbers in China must be huge.

I would add that the company is not a closed economic system. Those new jobs are usually a higher skill set than the workers displaced by the robots (maintenance, engineering, and programmers). Some companies 'invest' in re-training, others hire replacements that either paid for their own skills upgrade or got the taxpayer to pick up the tab. The point being, job growth of a company upgrading productivity by automation does displace lower skilled labor but enhances job growth for higher skilled workers.

So in a sense, Ann is correct that blue collar workforce is endangered by robots. If China loses work to robots, what will the billions of workers do?

Al, I think you're right about the consumer apps, at least in the  beginning. But these technologies will be capable of making--and re-making!--a lot of other stuff. I know it's hard to imagine--I felt like my brain went through a painful re-orientation during the reporting of this article--but I really think it's possible, even likely.

Rob, I think those are good, and accurate, observations about the differences between automation in the past and robots now. Robots are, in one sense, Factory Automation 2.0. The industry has already gone through all the 101/1.0 pain--poor implementation and poorly designed apps, since it was all new--and learned a lot of lessons. Plus. there are many, many companies who would like to replace human workers with robots.

Hey, Dave,

 

Good points. However, the additional profits may not go to more jobs. It may go to more robots.
