6. WORKING OF ULTRASONIC

7. TEMPERATURE SENSOR (LM35)

8. GAS SENSOR (MQ-2)

10. IR SENSOR
Used in this project to calculate wheel speed (as a tachometer)
IR Sensors work by using a specific light sensor to detect a light wavelength in the Infra-Red (IR) spectrum. By using a LED which produces light at the same wavelength as what the sensor is looking for we can look at the intensity of the received light.

14. CONCLUSION
From this project it is concluded that a half-duplex transmission of information is possible on same frequency by switching.
Robot is capable of automatic movement and sends information about its environment through the interfaced sensors.
Robot can be command to perform movement through interfaced keyboard.
