SMS controlled Surveillance robot is manual robot controlled through SMS sent from phone. Robot continuously transmits video towards user. This can be implemented using two methodologies.

1. IP (Internet Protocol) camera which send live surveillance video to dedicated website provided by manufacturer.

2. VGA camera capturing live video converting digital data and sending to microcontroller which will transmit data using GPRS available in GSM module which can be decoded at user side to watch live surveillance.

​

GPRS(General Packer Radio Service) available on GSM module sim-300 can be used. Whereas if IP camera uses internet link. GPRS increases range communication which allows remote communication of user and robot.

​

AVR microcontroller is used as the control unit of the whole embedded system. Motor drivers are used to drive motors of robot. AVR receives inputs from the camera(for USB VGA camera option), sensors, commands received by GSM/GPRS module. Depending on inputs and user's instructions microcontroller takes decisions to move the motors and drive the robot.
