Reflection for investagation

For the past 10 days we have started a new unit that was all about robots and how to make one. at the beggining we started at figuring out what a robot is made out of. For that i wrote some information such as A robot is a machine that neds power that can go into places that a human cant.an example to proof that is it can stay underwater for as long as it can.a robot is a autonomous machine that doesnt neeed food but it needs power.it also can be useful because it doesnt need to sleep but humans need to.another good thing about robots is that if you own a car company you dontneed to pay for the four things that make up a robot which are actuators,power, sensors and it needs a proceser. anothr thing i wrote is the three things of what robots are made up of, those three things are: Sensors are to inform about the environment and to let the robot know where to go.there are alot of diferent types of sensors such as line sensor, a line sensor only follows lines andsometimes it can get trapped inbetween a circle of lines.
Power:these are the wheelsA robot needs a battery so it can work, therefore the battery can besolar powered and energy powered but it will still make the robot moveso it can do what it needs to.Actuators:this is just control gear, levers, wheels, pulleys, and other outputdevices to keep the job going and done.Processorsthe processors can control the robot and basically tell the robot what action toperform depending on the sensors. it can be proximity sensors or white line sensors. disadvantges and advantages are:

• Advantages
  that robots can go to places where humans cant go such as underwater and in space such as the mars rover.
  they can work with acuracy
  they can work as long as they have batterys
  they can work for a long time and you dont have to feed them
  they can work very quickly
  they can give people jobs such as when they controll it people can process them and deighn them there is a certian quality
  products will turn out the same and there wont be differences
  

• Disadvantages
  people will lose jobs
  they are expensive
  sometimes malfunctions
  needs lots of care
  very sensitive robots
  there won t be anything rare or uniche
  some people will lose money
