THE WORLD SEEMED different this year, yes? Like something strange has been walking and rolling among us? Like we’re now sharing the planet with a new species of our own creation?
Well, we are, because 2017 was the year that the robots really, truly arrived. They escaped the factory floor and started conquering big cities to deliver Mediterranean food. Self-driving cars swarmed the streets. And even bipedal robots—finally capable of not immediately falling on their faces—strolled out of the lab and into the real world. The machines are here, and it’s an exhilarating time indeed. Like, now Atlas the humanoid robot can do backflips.
…Perhaps the biggest leap in hardware has been sensor technology. To build a robot you don’t have to babysit, you need it to sense its environment, and to sense its environment it needs a range of sensors. Not just with cameras, but with lasers that build a 3-D map of the robot’s surroundings. These kinds of components have gotten both far more powerful and far cheaper.
“I kind of talk about this finally being the golden age of robotics, and that means that for the first time in the last 12 months or so you see robots really becoming prolific,” says Ben Wolff, CEO of Sarcos Robotics, which makes the most bonkers robot arms you’ve ever seen. “And I think it’s because we’re finally at that crossover point, where the cost has come down of components while the capability of the components has increased sufficiently.”
Like, come down big time. One sensor cost Sarcos a quarter of a million dollars in 2010. Today, it’s $8,000—that’d be 3 percent of the cost just seven years ago. Other components like actuators—the motors in the joints of something like a robot arm—are also falling steadily in cost. Today, an actuator that once cost $3,500 is closer to $1,500. And it’s actuators, perhaps more than any other component, that promise to take robotics to the next level in the very near future.
