well....
i will be connecting the GPS receiver to the serial port female (DB-9).. and the male connector will be connected to the Max232 (RS232 level converter)..
and than it will be interfaced to the 8051 microcontroller....

GPS will receive the data as in the NMEA 0183 protocol signals.... the lats and longs will be inputted from the protocol signal into the program and so it will be like a 2-D coordinate system....

the final lat and longs will inputted through a 12 digit keypad and than the robot will have a hypothetical path towards the destination and the robot will move to the final location...

to detect the obstacles there will be SONAR sensors which will be connected to the microcontroller and they will give an interrupt to the moving robot and the robot will change its direction by rotating itself in the desired direction away from the obstacle....

and so the process will continue until the robot reaches the final location...


this is my idea.....
so i just want ur suggestions guys...
about the idea.....
how feasable it will be...
and anyone has made this type of robot before than is there any place where i am lacking....
and the components i am using.... i m using GPS 15, 8051 microcontroller, devantech SRF sonar sensors.....and the screen and keypad from an old cell pnone....

hey guys...
do reply....
