The robotics industry is looking to copy the successful software-as-a-service (SaaS) model as use of robots accelerates during the COVID-19 pandemic.

Why it matters: A major challenge to the spread of industrial robots has been their high initial cost. A model that charges companies regularly for robots based on use can offer better returns for robotics companies and widen their potential customer base.

What's happening: Due to concerns over vulnerable supply chains and the potential for infection of human workers, the COVID-19 pandemic has spurred growth in the robotics sector.

  • 41% of executives surveyed by Ernst & Young say they expect to accelerate automation because of the pandemic.
  • Since mid-April, the performance of the ROBO index fund, which tracks companies in the automation sector, has outperformed the S&P 500.

Yes, but: There are still plenty of obstacles holding back the automation wave.

  • Traditionally, industrial robots have been sold or leased to companies. That requires a potentially large one-time capital expenditure that could discourage some customers.
  • It also discourages VCs, since hardware companies rarely enjoy the revenue multiples that SaaS startups do.

In response, robotics companies are pursuing a robotics as a service (RaaS) model, where customers essentially subscribe to industrial robots as they might a cloud service like AWS.

  • New customers find it easier to employ an industrial robot if they know they can pay for it over the course of months or longer based on use, says Austin Badger, the director of Silicon Valley Bank's frontier tech program and the author of a new report on robotics.
  • "This leads to smaller and more mobile and specialized robots" that can service a number of industries," he says.

What to watch: Better financing models help, but ultimately we'll only see the robopocalypse if robots really can effectively replace human workers.

  • We're not quite there yet, as an Information story about Apple's struggles to expand the use of manufacturing robots in China demonstrates.

The bottom line: Everyone wants to be in the subscription business — including the bots.

Why Trump's visa ban makes Silicon Valley fume

As loud as the fight has been between the Trump administration and Big Tech over charges the industry censors conservatives, the White House's move to extend a ban on skilled-worker visas used widely by tech companies hits Silicon Valley closer to home.

The big picture: In a global tech economy where China and other countries threaten to surpass the U.S. in fields like artificial intelligence, 5G networking and automation, American CEOs treasure what they see as Silicon Valley's brain-and-innovation edge, and fear Trump's order will undermine that advantage.

China, public markets and secrecy

National security concerns drove a recent bipartisan Senate vote to crack down on Chinese companies that can hide their books from U.S. regulators even though they are publicly traded on U.S. exchanges, according to interviews with six current and former US. officials.

The big picture: The Holding Foreign Companies Accountable Act, which the Senate passed May 20, targets fraud and aims to promote transparency. But U.S. officials are also hoping to uncover hidden links between these companies and the Chinese government.

Tech firms blast Trump's extended H-1B visa restrictions

Tech companies reacted quickly and negatively Monday to news out of the Trump administration that it is extending a ban on entry of those with visas through the end of the year. Among those speaking out against the move are Facebook, Amazon, Google, Intel and Twitter, along with several tech trade groups.

The big picture: The Trump administration argues that visas like the H-1B widely used in the tech industry are responsible for taking jobs that American citizens could fill. Tech companies say they rely on these visas to fill positions with skilled workers from overseas when they've tapped out the American workforce.
