“…installation of these models indicate areas that are not detected by the ultrasonic sensor. To be more accurate in detecting the obstacle in front of the installation of ultrasonic sensor on a mobile robot with such large quantities such as 3 pieces [2], 8 pieces [3], 9 units [4] and some have installed 24 [5]. Other researchers combine 8 ultrasonic sensors with IR sensor [6].…”

The autonomous mobile robot can move around and avoid obstacles in front by itself. The data generated by the sensors is processed using an algorithm and specific methods to determine the movement of the robot. Ultrasonic sensor installed on the Mobile robot with a straight forward position. Ultrasonic sensor can detect the obstacle 30 degrees in front, which creates the blank area of the sensor between two ultrasonic sensors. Ultrasonic sensors installed at many points to reduce that blank area. This paper offers the concept of two ultrasonic sensor redirection by mounting it tilted so when it is drawn will form a right triangle that the concept of trigonometry applied. The results of the approximate distance between the obstacle sensor becomes the hypotenuse, while the distance between the two sensors already obtained so that the distance between the mobile robot with the real obstacle can be calculated. The mechanism of mobile robot movement mimics the movement of agricultural tractors. The test results showed that the optimum angle between the two ultrasonic sensors is 35 to 55 degree. Redirection ultrasonic sensors will reduce approximately 42% of the number of sensors that are installed straight ahead.

“…A semi autonomous robot presented by Stansfield and Bothma is still remote controlled and has Android device on both sides, but on the robot side it is used for interfacing an external distance sensor and also implements a simple collision avoidance algorithm [4]. A mobile robot presented by Lim, Lee and Tewolde is additionally to the previous robot uses the inertial sensors of the smartphone to improve indoor navigation capabilities of the robot [5]. Another robot takes advantage of the camera integrated in the smartphone for implementing image processing for line following [6].…”

The spreading of mobile robots is getting more significant nowadays. This is due to their ability to perform tasks that are dangerous, uncomfortable or impossible to people. The mobile robot must be endowed with a wide variety of sensors (cameras, microphones, proximity sensors, etc.) and processing units that makes them able to navigate in their environment. This generally carried out with unique, small series produced and thus expensive equipment. This paper describes the concept of a mobile robot with a control unit integrating the processing and the main sensor functionalities into one mass produced device, an Android smartphone. The robot is able to perform tasks such as tracking colored objects or human faces and orient itself. In the meantime, it avoids obstacles and keeps the distance between the target and itself. It is able to verbally communicate wit .

“…RELATED WORK Jognil Lim and SeokJu Lee proposed a strategy where smart phone in built sensor and ultrasonic sensor is used to navigate the robot in indoor environment, the main usage of smart phone is to measure the rotation angle and finally result shows that orientation sensor of smart phone gives better performance than encoder. [4] P.velrajkumar and A.Darwin Jose Raju proposed a remote device controlling robot using RF technology; it gives command from laptop to controller. It also has a camera unit which is used for tracking and image can be seen on laptop using window media encoder and the sole purpose of the robot is to explore the places where human cannot reach.…”

Robot can do a work with ease which seems to be impossible for a man and it becomes more helpful if one can able to control it wirelessly. Now a day robot is becoming a versatile and has a lot of features like one can control it by Smartphone, can avoid obstacles automatically, sense the environment and can send alert and now even it can diffuse the bomb and can perform almost all the critical task. The feature which is discussed in this paper is to use it in rescue and search mission. The robot can be controlled wirelessly using RF technology, has ultrasonic sensor for obstacle detection and it is also equipped with the smart phone camera to provide a Omni directional view and can send the video stream wirelessly to remote device which makes it easier to controlled the bot. The robot can explore those places where human cannot reach easily like the places suffered from natural disaster like earthquake, tsunami and hurricane.
