Set Up

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

Unidentified flying objects (UFOs) and other threats have recently approached and then vanished from our environment, posing a major threat to human safety. we designed a short-range obstacle detection system based on 8051 microcontroller to assist us in detecting this type of impediment and alerting us before we are wondered. To do this, we use a buzzer and an LED in our system, and we're aiming to develop a small system (SROD) to detect the object for detecting the object we used ultrasonic sensor as a radar so when the obstacle is detected by radar the distance is displayed on the LCD.

Distance Error

The Arduino UNO, ultrasonic sensor, servo motor, and Processing as visual software was used to create a low cost ultrasonic radar system that can detect and determine the location of an object, such as obstacles, in a short distance. Objects can be sensed up to 40 cm away from the ultrasonic sensor and the ultrasonic radar's angular rotation can detect objects from 15o to 165o and counterclockwise. The obstacle objects will be displayed in the computer panel by running the visual software. A comparative analysis of the distance error between the radar and the obstacles is used to assess the feasibility of the proposed system. The findings obtained from measurements of the obstacles are tabled to show that the planned design achieved a relatively small error, with 90% as the lowest accuracy.
