Robots can be used in many applications, for which, somewhere in the past, humans were used.

What are the advantages?

  • In many situations robots can increase productivity, efficiency, quality and consistency of products:
    • Unlike humans, robots don’t get bored
    • Until they wear out, they can do the same thing again and again
    • They can be very accurate – to fractions of an inch (as is needed for example in manufacturing of microelectronics)
  • Robots can work in environments which are unsafe for humans – in the nuclear or chemical industries for example
  • Robots don’t have the same environmental requirements that humans do – such as lighting, air conditioning or noise protection
  • Robots have some sensors/actuators which are more capable than humans

What are the disadvantages?

  • The use of robots can create economic problems if they replace human jobs
  • Robots can only do what they are told to do – they can’t improvise
    • This means that safety procedures are needed to protect humans and other robots
  • Although robots can be superior to humans in some ways, they are less dextrous than humans, they don’t have such powerful brains, and cannot compete with a human’s ability to understand what they can see.
  • Often robots are very costly – in terms of the initial cost, maintenance, the need for extra components and the need to be programmed to do the task.
