The True Love Tinder Robot Reads Your Skin Response to Swipe Left or Right

Looking for love online? Nicole He wants to lend a hand. To that end, He, a grad student at NYU, has designed the True Love Tinder Robot, a computerized system for those searching for The One on the dating app. "In a time when it's very normal for couples to meet online, we trust that algorithms on dating sites can find us suitable partners," He writes. She created the kit as a response to the idea that a computer "knows us better than we know ourselves."

The machine was built using an Arduino board, motors, LEDs, and a text-to-speech module. The system works, He explains, through a process called galvanic skin response, or "basically, how sweaty your palms get" in reaction to the Tinder photos that appear on your screen. The robot interprets that response as either positive or negative and uses a fake hand operated by servo motors to swipe accordingly. Engadget calls the invention a "modern spin on the classic love-tester machine," the penny arcade device that also used skin conductance to judge a couple's attraction.

Check out the video above to see the robot in action, and head to Nicole He's project page to learn more about how she built and coded the love machine.

After weeks of mailing out this year’s holiday cards, postage might be the last thing you want to think about. But the U.S. Postal Service has just given us a sneak peek at the many iconic people, places, and things that will be commemorated with their own stamps in 2018, and one in particular has us excited to send out a few birthday cards: Mister Rogers.

In celebration of the 50th anniversary of Mister Rogers’ Neighborhood, Fred Rogers’s groundbreaking PBS series that the USPS says “inspired and educated young viewers with warmth, sensitivity, and honesty,” the mail service shared a mockup of what the final stamp may look like. On it, Rogers—decked out in one of his trademark colorful cardigans (all of which were hand-knitted by his mom, by the way)—smiles for the camera alongside King Friday XIII, ruler of the Neighborhood of Make-Believe.

Though no official release date for Fred’s forever stamp has been given, Mister Rogers is just one of many legendary figures whose visages will grace a piece of postage in 2018. Singer/activist Lena Horne will be the 41st figure to appear as part of the USPS’s Black Heritage series, while former Beatle John Lennon will be the face of the newest Music Icons collection. Sally Ride, the first American woman in space, will also be honored.
