Yukai Engineering to Debut ‘AMAGAMI HAM HAM,’ Stuffed Animal Robot that Nibbles on Your Finger, at CES Unveiled & CES 2022

Cute robot is designed to give you innocent, comforting pleasure to brighten your day.

LAS VEGAS (Dec. 28, 2021) – At CES® Unveiled (Jan. 3), CES 2022 (Jan. 5-8) and ShowStoppers (Jan. 5), Yukai Engineering, a Tokyo-based robotics startup, will unveil “AMAGAMI HAM HAM,” a stuffed animal robot that nibbles on your finger. The robot adopts a character from Japan’s wildly popular “Nemu Nemu” stuffed animal series produced by LIV HEART CORPORATION. Designed to recreate the somewhat pleasing sensation that people get when human babies and pet animals softly bite on fingers, “AMAGAMI HAM HAM” is one of the latest works of Yukai Engineering, which is known for “creating robots that bring joy to life.” Yukai and LIV HEART plan to collaboratively launch a crowdfunding campaign for the robot in the spring of 2022.

The robot uses a special algorithm, “HAMgorithm,” to randomly select from two dozen “nibbling patterns” to keep users interested. 

“Most people like the nibbling sensation but know they need to teach their children or pets to stop it, because kids and animals will otherwise bite them with full force eventually. ‘AMAGAMI HAM HAM’ is a robot that frees humankind from the conundrum of whether ‘to pursue or not to pursue’ the forbidden pleasure,” said Yukai Engineering CMO Tsubasa Tominaga, who came up with the idea for the robot during the company’s internal hack-a-thon earlier this year. “It’s our hope that playing with this cute robot will comfort you and brighten up your day at CES 2022.”

HAMgorithm (HAM HAM algorithm) 

“AMAGAMI HAM HAM” is simple to use. Just insert your finger in the robot’s mouth, and it will begin nibbling. (In Japanese, “Amagami” and “ham” mean “soft biting” and “bite,” respectively.)

The company developed a special algorithm, “HAMgorithm,” which uses some parameters to select from two dozen “nibbling patterns” and create movements that keep users interested. Each pattern is created to evoke an image of a particular situation that might cause animals or babies to move their mouths, or the feelings that movement may provide to people who are nibbled. 

Pattern examples include, “Tasting HAM,” “Massaging HAM,” “Holding Tight HAM” and “Suction HAM,” among others.
