Robots are used to do repetitive tasks as per programmed instructions or remotely sent commands. One such robot is remotely controlled moving vehicle, used to detect dangerous objects or task which man or animal cannot do safely.
The intended wireless 'Embedded Based Robot' is controlled from remote place by sending moving commands to robot via SMS format. Both end needs GSM mobile/module and Mobile network to send SMS [Short Message Service]as commands.
Objective: To control the robot from remote end or wireless using SMS service of GSM network. There are four movement commands sent to Robot are: Forward, Reverse, Turn Left, and Turn Right.
The system has two parts: User end and Robot end. User sends robot movement commands in SMS format. The Robot end receives such transmitted command/SMS on its GSM module. Such SMS command is fed from GSM Module to UART pin of Microcontroller chip. The memory resident code/program of chip decodes the SMS form command into robotic command and send it to robot driver circuit for execution. The program of chip infinitely monitors its UART (Universal Asynchronous Receiver-Transmitter) port for received latest commands. Since UART port is used for communication, a level converter module is used as interface circuit between chip and GSM module.
The power supply unit supplies all needed power to run robotic system.The Display module shows the current direction or received/executed command information on its screen.
Note that using DTMF technique also same action is accomplished. This system needs GSM Mobile at user end and GSM mobile network to send SMS commands. There is no security for robotic operations, such as password facility, movement restrictions.
Applications:
The system can be used as 'Remote Operated Vehicle' and does dangerous work which normally human/animal cannot be done by.
The system can be used for robotic/study purpose or as spy vehicle by military division.
The system can be used as landmine/ore/fire detection work [with additional detecting modules], by security authority people.
