The devastating earthquake that struck his native State, and the recent earthquake in Haiti prompted Hiren Patel and a group of student from J T Engineering College in Gujarat, India, to develop a robot that senses an earthquake. It may be surprising to believe, but Hiren claims the earthquake sensing robot he has developed can sense vibrations in the earth three hours before an earthquake, thus warning the authorities against the danger well in advance.

Dubbed as the Earthquake Detector Robot, it is made of a single receiver and two transmitters whose circuits are kept inside the earth to sense changes in temperature and water levels and transmit the information about the changes via microwave frequencies. The internet controlled robot employs microcontrollers to sense vibrations and give off an alarm on detection. Though, three hours may not seem time enough to make significant arrangements to avoid destruction, if the robot actual works as claimed, many lives could be saved for sure.
