LAS VEGAS - Walking among the myriad expo booths at the Consumer Electronics Show in Las Vegas, one can get a pretty good idea of what lies ahead in the world of consumer technology — not only in home gadgets, but also on a highly professional level.

In all the areas on display — robots, autonomous cars, 3-D printers, drones and others — advances are bringing us closer to a highly automated future, as devices are becoming smarter and easier to use.

Drones that once required many hours of practice to avoid often-catastrophic crashes now perform air acrobatics, easily avoiding obstacles.

"Our goal is … once you receive it, it's ready to fly,” said Nicolas Texier of Parrot Company. “So, you open the box, you plug in the battery and it should be OK for you to control it as soon as you get it."

Service robots are entering everyday life, too. At airports, in hotel or hospital lobbies, they can replace humans for much lower pay and no complaints about extra hours of work.

And in the home, robots can already vacuum floors and clean large windows.

Cars, printers

Engineers developing self-driving cars say they have made enormous improvements in computational power and sensing capabilities.

"I think that the industry consensus is that the enabling technologies behind (self-driving cars) … should be fairly robust and mature within the next four to five years," said James Mcbride of Ford Motor Company.

In 2016, consumer-level 3-D printers will move closer to the status of “necessary household gadget,” while professional-level machines, which can print metal parts, will start changing entire industries.

"We are focused on titanium today because two critical industries live and die by their ability to do complex, very lightweight titanium parts,” said Cathy Lewis of 3D Systems Corporation. “In particular, we are talking about aerospace and defense, and we are talking about health care."

Experts say advances in other segments of technology — such as artificial intelligence, virtual reality, wearable gadgets and personal transportation devices — show that 2016 will be a very exciting year.
