The sensors are the powerhouse of a robot’s feedback system and act as eyes and ears. A wide
            range of sensors is used in a robot system to perform the tasks. These include:
                Cameras allow a robot to construct a visual picture of its background.

                Microphones are used to detect sounds.
                Thermometers in some robots are used to sense temperature.

                Light sensors use laser light to detect objects in the pathway.
                Sound sensors or Supersonic sensors use high-frequency sounds to detect objects.
                Temperature sensors sense temperature.

                Contact sensors are one of the most common sensors in robotics. They are used to detect changes
               in position, velocity, force, etc.
                Proximity sensors are used to measure the distance of any object from a robot.
                Pressure sensors sense pressure.

                Positioning sensors are used in the
               automation industries for accurate       Common sensors include cameras, microphones,
               robotic arm movement.                    accelerometers, gyroscopes, and proximity sensors.
            Power Supply

            Just like human beings consume food when they need energy, robots need energy too to function.
            Electricity is the primary source of energy for most robots. Stationary robots used in the factories
            use direct power. Mobile robots use high-capacity batteries. Robotic spacecrafts and satellites are
            generally equipped with solar panels.
