WatchTower, a LEGO Mindstorms EV3 security robot

WatchTower is a pretty self-explanatory robot. It detects intruders by sensing the vibrations they make while walking or digging beneath it. For this purpose, it uses a Gyro sensor, which could be incredibly sensitive under the right circumstances. The Ultrasonic sensor, that sits on top of a medium motor starts locating the intruder when the Gyro sensor detects it.
