It can be used to save human lives from a number of road accidents. To demonstrate such a low cost system, a distance sensor frmework, microcontroller, remotely controlled unit using radio frequency, and an alarm unit are utilizd. A navigation approach of the robot is also described based on the range sensors. To verify the presented strategy, the experimental test has been carried out in a real environment by moving robot between diferent vehicles and objects. Keords Accident avoidance system, Navigation, Remote control, Robots, Sensor network I. I NTRODUCTION To maintain a specifc safe distace fom aoher object is primaily about instructing a mobile robot to achieve the desired goal. I order to atan such objectives, one of the possible choices is to use the sensors. Robot progmng is utilized to attan information about their environment by using the extera sensors to allow for a more fexible execution. Recently numerous eforts have been put in the inteation of multiple sensors into robot systems because advaced robots need more information about surrounding environment. This work also demonstraes on the multiple sensor system ad mobile navigaion. The mobile robot ca get rage informaion aound itself fom the distace sensors. This infomaion is used for inspction of the environment aound the robot like deection of a entity, notice of the dager of collision, ad identifcaion of object position. Worldwide, lot of peole ae killed ad injured in road crashes every yea. And even with al the developments in te motor vehicle saety technology, the numbe of people killed in the automobile accidents keeps on rising. Accident causes include: driver ftigue (fequently yawning, misjudging trafc situation, drunk driving, using of drugs), looking at somewhere else, playing with music, reading douments, using cell phones, driving in fog, ad trafc high ligts. Some precations have been made for tafc acident safety issue which contains: Sea blt, child safety sea, ar ba, sped limitaion, ad by physical chage in vehicle desig. We have assumed tha b mounting sensors, light alam, sound alam, ad vibration module in vehicle will represent a aam sig to alert te driver. Vibraion module will help to focus the driver in a noisy environment. This security system will help a geat deal in 9781-61284-941-6/11/$26.0 ©2011 IEEE increasing road saety ad reduces collisions. I our syste the vehicle ca b contolled by huma as well as atomaically. The main issue for collision safety is to control te speed of vehicle. Te na tendec for self protection is ta drivers usualy reduce te speed of vehicle in uncertain conditions for decision maing. In this study, the sped of vehicle is aoaically controlled b using distace measurement wit the help of sensors. Maua mode contains sae hadwae ad sofwae for the vehicle which has been already placed in it. But for the prevention mode a extra hadwae ad sofwae will be installed. Te hadwae for prevention mode is inerrelaed wit the hadwae of maual mode which includes: sensors, alams, ad control unit. When te prevention mode is activaed, instructions ae sent towads the predefned apaus in te vehicle. Actually, we have implemented our proposed system on a robotic model. Our unique work o a mobile robot is based on the sensor method which acquires informaion to updae the robot position. Whe a mobile robt is in unknown environment, it will get position information fom the sesors. According to distace information, the mobile robot maintains its goal without crashing. This robot is driven by two DC motors ad robot does not require ay huma contacts othe tha using a remote control device for commads to the microcontroller. As soon as, the detection of a vhicle is confrmed ligt ad sound aams get ativaed gving a sigal of deection. These alams ae very cooperaive in case of one failure the oter will indicae te pesence. Here, methodical aproach is established for the development of sensor based robot which ca be used for security purpose to prevent fom the auomobile accidens also it ca be used in industria applications for ragng purposes. We ae inspired fom previous work on ultrasonic sensor based blind spot accident prevention system [I]. I [2] a deceleration control method of the automobile for collision avoidace based on driver's perceptual risk is discussed. The environmental informaion is gven by the GPS ad sensors. Numerous works on a remote controlled mini robt have bee already being proposed [3]. Laser rage sensors ca aso be used for object deection, measurements, ad to get informaion about surrounding. A lot of study is proposed to control mobile robot based on information of the scaning laser rage sensor [4]. Infaed sensor ring is used for line based incremental map building [5]. Navigtion techniques ae used to move a robot fom one position to aother as describd in [6]-[8]. 251
