Abstract:
Robot is invented as imitation to human actions. Within short time the robots occupied major role in many applications as replacement to humans. It is proven in case of security applications, military, aeronautical, navigation and many more. For example if there is any urgent attention at some place where a human cannot entire or work, our robot does that work.
We can prepare many robots for many applications as per the requirement. Among all Security is primary concern for everyone. Here we are with robot with wireless camera, which can be help, us to monitor the remote areas for security purpose without direct involvement of human beings.
This Robot is controlled either through wire or wireless. Here, the robot is fixed with one wireless camera. While controlling the robot, object moving in front of the robot will be displayed on the display unit either on TV or Compute. In this project the robot will be controlled through wireless communication RF. The wireless communication between the remote areas will be achieved by using the RF modules called RF transmitter and RF receiver. The project is designed in such a way that we will interface switches to RF transmitter to control the robot which will be connected on the receiver side. Hence the encoded data will be transmitted by the transmitter over the medium and will be received by the RF receiver which will be interfaced to the controller through an RF decoder, on the receiver side. The RF decoder is used to decode the received data into a 4 bit digital data which will be fed to the controller. So now the controller will perform the predefined tasks by monitoring the received decoded data. The robot will be interfaced to the controller through DC gear motors. RF transmitter is given to the user and the transmitter of the wireless camera is fixed at robot along with camera.
This project uses Ultrasonic sensor, Smoke sensor, regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer
