Seiko Epson Shows Off Its Dual-Arm Robot

It's smart, adaptable, and looks like E.T.

Often equipped with two arms, strange hands, and even stranger-looking heads, a new breed of jack-of-all-trades industrial robot could change the face of automation. And the place to see the latest examples of these dual-arm manufacturing machines was the International Robot Exhibition (IREX) in Tokyo earlier this month.

We're putting together an in-depth article and video on the dual-arm, adaptable industrial robots we saw at IREX. But today we're going to focus on one of them, because that's a new robot we've never covered before.

It's a new prototype from Japanese electronics company Seiko Epson. The robot doesn't have a name yet (the company calls it simply "autonomous dual-arm robot"), but we can't help noticing that it looks like E.T. Epson plans to market it by early 2016.

Epson is no stranger to industrial manufacturing robots, boasting the lion's share of global SCARA robot sales (one model pictured below). However, specialized industrial robots aren't easily assigned new jobs, since they're often carefully integrated into permanent positions in the production line. In the past, the main solution has been manual labor. The new generation of adaptable robots could change that with a combination of sensing, delicate manipulation, and the ability to learn new tasks more easily.

"In the future, a commercial version of this autonomous dual-arm robot will make it possible to easily automate a wide range of tasks that previously had to be performed by hand," said Hideo Hirao, chief operating officer of Epson's industrial solutions division. The robot could be moved from one end of a production line, where it assembles goods, to the other end where it picks up and places objects into packages, he added.

Epson provides some more details in a press release:

"Epson's autonomous dual-arm robot is able to accurately recognize the position and orientation of objects in three-dimensional space. The two robot arms are equipped with newly developed force sensors that give the robot human-like control over the force exerted by the arms, enabling the robots to transport and assemble objects without damaging them. A multipurpose end effector can grasp, clamp, and insert objects of various shapes and sizes. The robot can be made to perform a wide range of tasks simply by teaching it objects and task scenarios."

If all that sounds like what we've heard about other robots like Rethink Robotics' Baxter, ABB's Frida, or Kawada Industries' Nextage, it's no coincidence. That's definitely one of the hottest trends in industrial robotics. However, there remains the rather important issue of price, which Epson is not yet ready to disclose. If the company's dual-arm robot has a competitive price, Epson—already a big player in the SCARA market—is in a strong position to enter this new era of manufacturing automation.

By 2050, the global population aged 65 or more will be nearly double what it is today. The number of people over the age of 80 will triple, approaching half a billion. Supporting an aging population is a worldwide concern, but this demographic shift is especially pronounced in Japan, where more than a third of Japanese will be 65 or older by midcentury.

Toyota Research Institute (TRI), which was established by Toyota Motor Corp. in 2015 to explore autonomous cars, robotics, and “human amplification technologies,” has also been focusing a significant portion of its research on ways to help older people maintain their health, happiness, and independence as long as possible. While an important goal in itself, improving self-sufficiency for the elderly also reduces the amount of support they need from society more broadly. And without technological help, sustaining this population in an effective and dignified manner will grow increasingly difficult—first in Japan, but globally soon after.
