Another example of a temperature sensor used in robotics is a Resistance Temperature Detector (RTD). An RTD
        is a type of temperature sensor that uses the change in electrical resistance of a metal wire with temperature.
        Typically, platinum or nickel is used as the sensing element. As the temperature changes, the resistance of the
        wire changes, and this change can be measured to determine the temperature. RTDs are known for their high
        accuracy and stability over a wide temperature range. They are often used in robotics for precise temperature
        measurement in applications such as thermal mapping, temperature control in manufacturing processes, or
        environmental monitoring.

        For instance, a robot working in a controlled environment may be equipped with RTDs to monitor the ambient
        temperature and ensure that it remains within specific limits for optimal operation.
        Other types of temperature sensors used in robotics include thermistors, which are temperature-sensitive
        resistors that exhibit a large change in resistance with temperature, and infrared temperature sensors, which
        measure temperature by detecting the infrared radiation emitted by objects.

                      Brainy Fact

              The Institute of Science and Technology, Korea created a sprinting robot named Raptor. The robot
              is designed to sprint faster than a human, running as fast as 46 kilometers per hour. Above all, this
              robot is inspired by the Velociraptor, a dinosaur from the Cretaceous Period which can run up to
              64 kilometers per hour



        Range and Proximity Detection Sensors
        The range and proximity detection sensors are types of sensors used in robotics to measure the distance between
        the robot and objects in its environment. They provide information about the proximity of objects, allowing the
        robot to detect obstacles, navigate safely, and perform tasks requiring accurate distance measurements. Let’s
        explore two examples of range and proximity detection sensors commonly used in robotics—ultrasonic sensors
        and infrared sensors.
           • Ultrasonic Sensors: Ultrasonic sensors use sound
           waves to measure distance. They emit high-
           frequency  sound waves and measure the time it
           takes  for the sound waves to bounce back after
           hitting an object. By knowing the speed of sound in
           the medium, the sensor can calculate the distance
           to the object.
