Japanese Researchers Developing Robotic Chameleon, Tongue First

The world desperately needs a robotic chameleon, and we're now one projectile-tongue closer to that goal

Japanese Researchers Developing Robotic Chameleon, Tongue First

Tomofumi Hatakeyama and Hiromi Mochiyama have not yet created a robotic chameleon like the (completely fake) one in the above pic, but they have started in on one of the most important parts: the tongue. Chameleons can shoot their tongues out to capture prey in just three one-hundredths of a second, and then reel their tongues back in and chow down. Seems like a handy thing for a robot to be able to do, right? Sure, why the heck not!

This system is deceptively simple, relying on an air cannon of sorts to fire a magnetic projectile attached to a thin elastic cord. Over 90 percent of the time, the robotic tongue can snap up magnets dropped 0.7 meter away, taking barely a tenth of a second to traverse the distance, and making the entire round trip in another tenth. It's wicked quick, and can nail almost exactly the same spot in mid-air every time.

Obviously, there are a few reasons why this particular version is probably not going to replace a real chameleon any time soon. For one, it only works on magnetic stuff, and in order to make the catch, it needs a break-beam sensor to tell it when to fire. But there are ways to get around both of these issues, like maybe some gecko-foottape plus a laser sensor system or something. The researchers want this thing to ultimately shoot out to 10 meters (!), and they're planning to mount it on some kind of mobile robot platform that will scuttle around and catch cockroaches and other bugs. You know, humanely.

"Shooting Manipulation System with High Reaching Accuracy" was presented by Tomofumi Hatakeyama and Hiromi Mochiyama from the University of Tsukuba at the IEEE International Conference on Intelligent Robots and Systems in San Francisco last week.

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.
