A.I Tivi | World’s first ‘molecular robot’ capable of building molecules | Tech


world’s first molecular robot capable of
building molecules date September 20th 2017 source University of Manchester
summary scientists have created the world’s first molecular robot that is
capable of performing basic tasks including building other molecules
scientists at the University of Manchester have created the world’s
first molecular robot that is capable of performing basic tasks including
building other molecules the tiny robots which are a millionth of a millimeter in
size can be programmed to move and build molecular cargo using a tiny robotic arm
each individual robot is capable of manipulating a single molecule and is
made up of just 150 carbon hydrogen oxygen and nitrogen atoms to put that
size into context a billion billion of these robots piled on top of each other
would still only be the same size as a single grain of salt
the robots operate by carrying out chemical reactions in special solutions
which can then be controlled and programmed by scientists to perform the
basic tasks in the future such robots could be used for medical purposes
advanced manufacturing processes and even building molecular factories and
assembly lines the research will be published in nature on Thursday 21st
September professor david lee who led the research at universities school of
chemistry explains all matter is made up of atoms and these are the basic
building blocks that form molecules our robot is literally a molecular robot
constructed of atoms just like you can build a very simple robot out of Lego
bricks the robot then responds to a series of simple commands that are
programmed with chemical inputs by a scientist it is similar to the way
robots are used on a car assembly line those robots pick up a panel and
position it so it can be remitted in the correct way to
build the bodywork of a car so just like the robot in the factory our molecular
version can be programmed to position and rivet components in different ways
to build different products just on a much smaller scale at a molecular level
the benefit of having machinery that is so small is it massively reduces demand
for materials can accelerate and improve drug discovery dramatically reduce power
requirements and rapidly increase the miniatures a ssin of other products
therefore the potential applications for molecular robots are extremely varied
and exciting professor Lee says molecular robotics represents the
ultimate in the miniaturization of machinery our aim is to design and make
the smallest machines possible this is just the start but we anticipate that
within 10 to 20 years molecular robots will begin to be used to build molecules
and materials on assembly lines and molecular factories whilst building and
operating such tiny machine is extremely complex the techniques used by the team
are based on simple chemical processes professor Li added the robots are
assembled and operated using chemistry this is the science of how atoms and
molecules react with each other and how larger molecules are constructed from
smaller ones it is the same sort of process scientists used to make
medicines and plastics from simple chemical building blocks then once the
nano robots have been constructed they are operated by scientists by adding
chemical inputs which tell the robots what to do and when just like a computer
program
