Play Rock-Paper-Scissors against this animatronic hand

Talk to the (robotic) hand! 

Those looking for a friendly game of “Rock-Paper-Scissors” will be happy to learn of this recent project from our friends at littleBits. While it may not be nearly as high-tech as the unbeatable one from Japanese researchers at the Ishikawa Oku Laboratory, it is impressive nevertheless. Even better, it’s simple to build and play.


The Watson-like gadget is comprised of two parts: the robot and a glove. The robot is controlled by a littleBits Arduino module (ATmega32U4) and programmed to randomly move into either rock, paper, or scissor position when prompted by you. Meanwhile, the glove includes a start button along with two bend sensors on both the index and middle finger. When the button is pressed, the wireless interaction is triggered and a countdown begins. “1,2,3 shoot.”


Choose your hand position, and the animatronic hand will do the same. A wireless module sends what you’ve played to the embedded Arduino module inside the robot. At that point, the robot will choose its playing hand, compare the two results and emit a tune depending on whether you won, lost or tied.
