|Most of us think of the game rock, paper, scissors as a game of chance.
Some of us, like Douglas Walker, co-author of the Rock Paper Scissors
Strategy Guide, consider it a game of physical and psychological skill.
And then there are the scientists at the University of Tokyo's Ishikawa
Oku Laboratory, makers of the Janken robot, who have turned the game
into an impossible endeavour. You cannot beat the Janken robot at rock,
paper, scissors. The robot will always win.
So how does the robot always win? The answer is simple: The robot
cheats. The researchers explain that the robot makes its move one
millisecond after its human opponent has made his or her move. The wrist
joint angle of the robot hand is controlled based on the position of the
human hand. The vision recognises one of rock, paper and scissors based
on the shape of the human hand. After that, the robot hand plays one of
rock, paper and scissors so as to beat the human being in 1ms.
A robot that will win rock, paper, scissors 100% of the time sounds kind
of annoying to us, but the researchers said the technology shows the
possibility of cooperation between humans and machines in just a few
milliseconds. The researchers suggest this technology can be applied to
motion support of human beings and cooperation work between human beings
and robots without time delay.
