ABSTRACT
A robot is an automatically operated machine that replaces human effort, though it may not resemble human beings in appearance or perform functions in a humanlike manner. It is capable of being programmed in advance and is designed to execute one or more tasks repeatedly, with speed and precision. For successful completion of tasks, robots have to perceive the world around them, the workspace in which they operate. At the heart of this perception are the inputs from a gamut of sensors. Sensors and measurement techniques increase the versatility of robots. Nature is a rich source of inspiration for the development of sensing and measurement systems. Whole gamuts of sensors are used in robotic systems, from simple to very complex and sophisticated. Temperature sensing technology is one of the most widely used sensing technologies in the world of sensors. Biological sensors typically exhibit low-energy requirements, high sensitivity, and redundancy.
