Design the Robot as Security System in the Home

Mobile robots are now widely used in various security and surveillance applications. The contribution describes a design of the robot with the function of the security system in the home. This robot can be controlled by mobile phone using DTMF or hobby RC system. In case of unavailability of operator, robot can operate in autonomous mode too. In this mode, robot automatically reacts to stimuli from the environment e.g. If motion detector detects movement, robot can automatically start recording video from camera. As propulsion system, two modified RC servos were used. Robot has many sensors e.g. PIR movement sensor, gyroscope, infrared distance sensors, ultrasonic distance sensor. Some of these sensors can be manipulated by servos. On top, there is a video camera. This camera is capable of recording or transmitting audio and video over mobile phone using 3G video calls.
