The basic schematic diagram is shown above. A wireless camera is mounted on the robot body for spying purposes, even in complete darkness by using infrared lighting. The RF transmitter acts as an RF remote control that has the advantage of adequate range (up to 200 meters) with a proper antenna, while the receiver decodes before feeding it to another microcontroller to drive DC motors via motor driver IC for necessary work. In the transmitting end pushbuttons are used commands are sent to the controller for controlling the movement of the robot either in forward, backward, left, right, directions. War Field Flying Robort with NJight Vision Flying Camera All these motors used on conveyers are designed to be synchronized. This project is applicable to many industries like steel plants, paper plants, and textile mills, where the motors are used to design simultaneously. This system is used to synchronize motor speed by using RF technology. Speed Synchronization of Multiple Motors in Industries A robotic vehicle with the metal detectorġ).War field flying robot with a night vision flying camera.Speed synchronization of multiple motors in industries.The applications of types of encoder and decoder include the following Please refer to this link to know more about Encoder and Decoder MCQs Applications Of Encoder and Decoder If the circuit is disabled, then none of the outputs are equal to zero. The circuit is disabled when E’ is equal to one, regardless of the values of the other two inputs. The outputs represent the minterm selected by the inputs A1 and A0. As represented by the truth table, only one output can be equal to zero at any given time, all other outputs being equal to one. The decoder is enabled when E’ is equal to zero. The circuit operates with complemented outputs and enables input E’, which is also complemented to match the outputs of the decoder NAND gate. 2-to-4 line decoder with an enable input constructed with NAND gates. In this case, all decoder outputs will be 1’s except the one corresponding to the input code which will be 0. Some decoders are constructed with NAND rather than AND gates.
