 Solar Based Robot Control using Voice Recognition
                    Technology
                                              Abstract
                The speech recognition system is a useful and easy to use programmable
speech recognition circuit. Programmable, in the sense that user can train the words (or
vocal utterances) he needs the circuit to recognize. This board allows the user to
experiment with many facets of speech recognition technology. It has 8 bit data out
which can be interfaced with any microcontroller for further development. Some of
interfacing applications which can be made are controlling home appliances, robotics
movements, Speech Assisted technologies, Speech to text translation, and many more.




       Robotics has been of interest to mankind for over hundred years.
However our perception of robots has been influenced by the media and
Hollywood. The vast majority of robots do have several qualities in common. First of
all, almost all robots have a movable body. Some only have motorized wheels, and
others have dozens of movable segments, typically made of metal or plastic. Like the
bones in your body, the individual segments are connected together with joints.




This robot is controlled by voice commands. This can be moved forward and reverse
direction using geared motors of 60RPM. Also this robot can take sharp turnings
towards left and right directions. This project uses AT89S52 MCU as its controller. A
high sensitive induction type metal detector is designed using colpitts oscillator principle
and fixed to this robot. Also a wireless camera with voice is interfaced to the kit.




       This project uses 12V battery. A solar panel is connected to this. The battery gets
charged in the day time and the stored energy can be used for robot operation.
