The project aims at designing an intelligent voice operated fire extinguishing
robotic vehicle which can be controlled wirelessly through RF communication. The
Robotic vehicle has a camera mounted on it whose direction can also be controlled using voice commands. The proposed vehicle has a water jet spray which is capable of
sprinkling water. The sprinkler can be moved towards the required direction.
The advent of new high-speed technology provided realistic opportunity for new
robot controls and realization of new methods of control theory. This technical
improvement together with the need for high performance robots created faster, more
accurate and more intelligent robots using new robots control devices, new drivers and
advanced control algorithms. This project describes a new economical solution of robot
control systems. The presented robot control system can be used for different
Sophisticated robotic applications. Speech is the primary and most convenient means of communication between humans.
Whether due to technological curiosity to build machines that mimic human's or desire to automate work with machine, research in speech recognition as a first step towards human-machine communication. Speech recognition is the process of recognizing the spoken word to take necessary actions accordingly. The controlling devices of the whole system are Microcontrollers.
Speechr ecognition module, wireless transceiver modules, obstacle detector, lamp, water jet spray, DC motors and buzzer are interfaced to Microcontroller. When the user fed the voice commands to the speech recognition module, the microcontroller interfaced to it reads the command and sends relevant data of that command wirelessly using transceiver module. This data is received by the transceiver module on the robotic vehicle and feds itto microcontroller which acts accordingly on motors, pump and lamp. The vehicle is mounted with a camera which helps in viewing the live images on TV. Also, the vehicleis capable of detecting obstacles and alerts the user through buzzer. To perform this
