Prof. Dr. Murat AKSOYUsage of microcontroller has been grown up extremely in electronics andcomputer fields. Nowadays microcontroller based wireless control applications arebegun to use in many applications. It is so important to control a system from centralpoint, to prevent wasting time, a place where dangerous for human, a place where isnot reachable, a place where it is so hard to work. The main aim of this study is bothto control a remote device by establishing a serial communication betweenmicrocontroller and computer wirelessly and to get image and temperature datarelated to location where device is.A model car has been chosen as a device (Robot) to be controlled. Threemotors have been selected on robot car for forward-reverse motion, change direction(left-right) and 360° rotation of camera mounted on the top of the robot car. Controlcard on the robot car manages the related motors in accordance with signal comingfrom the computer and IR sensor. DC motor selected for forward-reverse motion ofrobot car can work in two directions and four different speeds. The differentsequential speeds are executed by PWM (Pulse Width Modulation) signal. If therobot car face with an obstacle, it has an ability to stop without crashing to thatobstacle. In addition to this, when the robot car enters into a dark area such as tunnel,far lamps are switched on. A couple of RF modem module has been used in order toprovide wireless communication between computer and robot car. A user interfacehas been established on computer to send commands to robot and images receivedfrom wireless camera can be viewed on the computer screen simultaneouslyKeywords: Robot Car, Microcontroller, Control card, RF Modem, User InterfaceI
