Our GPS Navigation Robot holds a micro processor and three micro controllers for multi task assignment.
The camera action, memory allocation, motor action and GPS way point verification are the synchronous process, where the continuous clock pulse is required.
Here by we use the Control Architecture,
ARM 9 with VME bus based micro processor.
ARM 7, ATMEL 89C51, Motorola 69HC11 are the three micro controllers used for speed and motion control drivers, GPS sensors and E-stop and Image Processing analysis respectively.
All the data has been send through IEEE 1394 fire wire bus controlled at fixed sequence.
