What is Robot?

  • Powered by Electricity.
  • Programmed to carry out certain tasks, like cleaning, etc.
  • Senses the environment using sensors and reacts accordingly on its own.

THE ‘SKELETON’

  • What is a body without a skeleton? Nothing but a soft sac, without the rigidity, and the shape that defines it.
  • Here, the only difference between the robot and us is that it is not exactly a spongy sac; it is a hard sac, with a lot of dismantled parts.
  • Our skeleton has bones, a robot’s skeleton is a robot chassis or simply a chassis – it is a frame (in our case a base plate) onto which everything - the actuators, the effectors, the wheels, the castor, the grippers, the brain - is attached and supported.

THE ‘SENSES’

  • A sensor is a device that detects input from the outside world and responds to it.
  • Just like we have many different types of senses and different ‘sensors’ for them, such as eyes for seeing, ears for hearing, nose for smelling, tongue for tasting, and skin for touching, robots are also capable of sensing different things such as light, sound, and temperature, and have many different sensors for them.

THE ‘e-BRAIN’

  • The robot has detected all that is happening around it. Now, it has to respond to it. But it needs to make sure that it does to correctly. Who or what is going to tell him what to do, and how to respond in the right way?
  • The brain is responsible for controlling all the senses, and, functions of the body, such as thinking (I think, therefore I am), eating, sleeping, and moving the arms and the legs.
  • The robot’s brain also does the same. It controls what it thinks, what it does, and how it moves its arms and legs.

THE ‘e-BRAIN’

  • At this moment, our robot’s got everything; right from the brain down to the feet. But since it is not exactly a human, it still doesn’t know as of yet what to do and how to do it.
  • You will give commands to the robot and ask it to do what you want him to, and he has to follow them!
  • These commands that we are talking about are nothing but the instructions that are given by writing a program for the specified task.
