ULTRASONIC DISTANCE MEASURE ROBOT [ULTRA-4]

Abstract

Ultrasonic sensors are ideally suited to accurate, automatic distance measurement in normal and difficult environments. Ultrasonic sensors are particularly suitable for environments where optical sensors are unusable such as smoke, dust and similar. Ultrasonic sensors are very accurate, stable and can be used over large ranges. Ultrasonic sensors can measure the following parameters without contacting the medium to be measured Distance Level Diameter Presence Position Ultrasonic sensors make accurate measurements in many difficult environments and unusual materials. Measurements are unaffected by: Material Surface Light Dust Mist and Vapour ULTRA-4 or ultrasonic distance measure robot is a robot which perform many action such as it gives the actual position of wall or obstacle which comes in front of it, measures the distance which displayed by 7-segment and also show the moving images of the objects by camera. The application area of ultra-4 is very wide such as rescue operations, spy robot, versatile use in autonomous technology, use in mining, it has found essential use in light industry (e.g. toy industry) agriculture and power engineering and used in car parking system.
