For several decades, various types of
artificial intelligence kept shocking the world. Robots could {#blank#}1{#/blank#} people in highly competitive games and then quickly destroyed
their human competitors.
AI long ago mastered chess, the Chinese
board game Go and even the Rubik's cube, which it managed to solve in just 0. 38
second.
Now machines have a new game that will
allow them to {#blank#}2{#/blank#} humans: Jenga, the popular
game in which players {#blank#}3{#/blank#} remove pieces from an
increasingly unstable tower of 54 blocks, placing each one on top until the
entire structure would {#blank#}4{#/blank#}.
A newly released video from MIT shows a
robot developed by the school's engineers playing the game with surprising
accuracy. The machine is equipped with a soft gripper (夹子), a force-sensing wrist and an external camera, allowing the
robot to detect the tower's {#blank#}5{#/blank#} the way a human might do
Unlike in purely recognitive tasks or games
such as chess or Go, playing the game of Jenga also requires mastery of
physical acts such as pushing, pulling, placing, and arranging pieces. It must {#blank#}6{#/blank#} interactive physical operation, where you have to touch the tower
to learn how and when to move blocks.
Imitating it is rather difficult, so the
robot has to learn in the real world, by working with the real Jenga tower.
Recently, a relevant research was published in the journal Science Robotics.
Researchers say the robot demonstrates that machines can learn how to perform
certain tasks through actual touching instead of relying heavily on visual {#blank#}7{#/blank#}. That physical {#blank#}8{#/blank#} is significant,
researchers say, because it provides further proof that robots can be used to
perform {#blank#}9{#/blank#} tasks, such as separating
recyclable objects from landfill trash and assembling consumer products.
In a cellphone assembly line, the felling
of any component is coming from force and touch rather than vision. To become
an accomplished Jenga player, the robot did not require as much repetitive
practice as you might imagine. Hoping to avoid reconstructing a Jenga tower
thousands of times, researchers developed a method that allowed the robot to be
trained on about 300 games. Researchers say the robot has already begun facing
off against humans, who remain {#blank#}10{#/blank#} players—for now.
