Position of sensors

                  In very last article, we have seen the circuit diagram of a infrared transmitter - Receiver pair. Apart from the circuit diagram for the sensors in an Autonomous Robotic system, the position of sensors is also an important thing. In this article, I will present the sensor position of an AR system with some explanation.
There are two examples for sensor position, as below

          In these examples, one thing is noticeable; around centered sensors, there are two vertical lines which are 3 cm apart. In the last article Circuit diagram for sensor, I have considered a case that an AR ( autonomous system )  has to follow a 30mm (3cm) line. That's why, centered sensor place is restricted between a 3 cm (30mm) line. One can restrict the place of sensors outward the vertical line also. There are number of possibilities to place sensors. Out of which I had used both these cases which are shown in the diagrams above, and it really works 100%  for programming an embedded system. It gives huge extension for programming.
          That's it for now, very soon I will explain working of widely usable sensor which is TCRT5000.
