Distance Measuring Robot (DMR)
[attachment=36363]
ABSTRACT
Distance Measuring Robot (DMR) is one among the industrial robots which are used in different fields for distance measurement. DMR makes use of ultrasonic as well as infrared sensors to measure the distance of obstacle. Our approach to the use of sensors for measuring distances is based on the ideology that the use of expensive transducers and complex signal processing techniques should be avoided if we want a better cost-performance ratio compared to that of more sophisticated imaging systems, such as the ones based on laser scanning. Ultrasonic sensors are more suitable for measuring distances. They have provided a reliable source of obstacle detections. Since they are not vision-based, they are useful under conditions of poor lighting and transparent objects. As the human ear’s audible perception range is 20 Hz to 20 kHz, it is insensitive to ultrasonic waves, and hence the ultrasound waves can be used for applications in industries/vehicles without hindering human activity.
Distance measurement robot makes use of ultrasonic sensors to measure the distance of obstacle. It also uses components such as LCD displays, motors, microcontroller.US sensors have a transmitter and a receiver to send and collect the high frequency sound waves. Microcontroller (AT89C51) is programmed such that as it reaches the obstacle, the robot can be moved.
