These robotic rings that imitate eye and mouth movements are being developed by a research group at Keio University.

“When you wear this robot on your hand, it forms a medium for communication using the hand. So the robot serves as a device for enhancing the animal-like, imitative ways that people use their hands.”

“The robot has electromagnetic motors in the eyes, which are controlled electrically. This bottom part contains a microcontroller to move the eyes, and a battery.”

“Until now, robots have usually communicated with people from a distance. That’s also true of pet robots like AIBO, and androids. Until now, robots haven’t been attached to the human body. We’ve designed this ring-shaped robot as an entertaining communication device, like an accessory that’s fun to wear, to help wearable robots progress beyond the research stage.”

“First of all, this device resembles a toy. So we want to make it more like a character, like when children or their parents play finger games. That would enable a new form of interactive play. We’d also like to incorporate this robot into the way children use their hands to communicate with each other.”
