our aim is to develop a project that will benefit society. But nowadays it is employed to assist human in surveillance, rescue and recovery missions. This paper presents the prototype model of an UGV which is operated wirelessly through manual navigation commands based on the live video captured from the IP camera mounted on the board. The distance measurement is done by the Ultrasonic sensor from the obstacle and displayed in the LCD. The target tracking as well as attacking is done based on the obstacle and environment situation monitored in the live video. This complete set up and working of the UGV is described further in this paper

ABSTRACT A research has been conducted to make an object detector prototype using ultrasonic sensor for indoor security monitoring system. The testing object placed in front of the sensor and the measurement conducted in distance and angle variations. For indoor implementation, graphical display of object detection on computer screen given by blue-to-yellow transition to indicate the nearing object and its reverse to indicate the fading object. The trend of accuracy of the object distance measurement has a declining linear pattern, it means that the accuracy of object detection will decrease if the distance and or angle from the object to the detector are increase. Keywords: object detector, ultrasonic sensor,  indoor security monitoring   PURWARUPA DETEKTOR OBJEK MENGGUNAKAN SENSOR ULTRASONIK UNTUK SISTEM PEMANTAUAN KEAMANAN DALAM RUANGAN ABSTRAK Sebuah penelitian telah dilakukan untuk membuat purwarupa detektor objek menggunakan sensor ultrasonik untuk sistem pemantauan keamanan dalam ruangan. Objek pengujian diletakkan di depan sensor dan pengukuran dilakukan pada variasi jarak dan sudut.  Untuk implementasi dalam ruangan, tampilan grafis pendeteksian objek pada layar komputer diberikan oleh transisi warna biru ke kuning untuk menunjukkan objek yang mendekat dan kebalikannya untuk menunjukkan objek yang menjauh. Tren akurasi pendeteksian objek memiliki pola menurun secara linear, itu berarti bahwa akurasi pendeteksian objek akan berkurang jika jarak dan atau sudut dari objek ke detektor bertambah besar. Kata kunci: detektor objek, sensor ultrasonik, pemantauan keamanan dalam ruangan

The project we designed is used to develop a distance measurement system using ultrasonic waves and interfaced with Arduino UNO. We know that the human audible range is from 20hz to 20khz. We can use these frequency range waves through ultrasonic sensor HC-SR04. The main advantages of this sensor are when this sensor is interfaced with Arduino which is a control system and a sensing system, a proper calculation of the distance measurement can be done by using different types of new techniques. As huge amounts are spent on hundreds of inflexible circuit boards, the Arduino board will allow the business to bring many more unique devices. These distance measurement systems are mostly used as range meters and as proximity detectors in the different types of industries. The hardware part of the ultrasonic sensor is interfaced with the Arduino Uno board. This type of measuring distance is an efficient way to measure even small distances accurately. The distance of an object from the sensor is measured by using an ultrasonic sensor. After knowing the speed of the sound wave the distance of an object can be calculated.

In order to overcome the limitation, some traditional distance measurement methods in some special occasions go beyond measure flaw. This design centres on P89LPC932 and realizes non-contact air measurement by use of an ultrasonic sensor, which fully considers the close relationship of velocity and temperature, thus temperature compensation, further get measurement distance about 700cm, optimal precision at 1%. This design has some features, such as the strong anti-jamming capability, simple installation, small size, low power consumption, easy to embed in other system.

The main objective of this paper is to develop an automated braking system to avoid frontal collision of the vehicle due to driver inattentiveness. The working model comprises of automated braking system which includes ultrasonic sensor, bike brake system, high torque motor, microcontroller, motor driver, battery, double acting cylinder and solenoid valves. An algorithm is proposed for automated braking system. The proposed working model is validated with experimental results. The ultrasonic sensor is validated for distance measurement and the sensor predicts the distance with an error of 3.31 percent.
