System Design/ MethodologyThe PIC16F873A and PIC16F874A have one-half of the total on-chip

memory of the PIC16F876A and PIC16F877A

The 28-pin devices have three I/O ports, while the 40/44-pin devices

have five

The 28-pin devices have fourteen interrupts, while the 40/44-pin

devices have fifteen

The 28-pin devices have five A/D input channels, while the 40/44-pin

devices have eight

The Parallel Slave Port is implemented only on the 40/44-pin devices.

AdvantagesIt is a small unmanned fully autonomous and a light weight vehicle

and therefore it can be fielded in narrow passage very easily. As it is fully autonomous no controlling is required.

Due to its light weight power requirements are less and easy to carry.

Its microcontroller based circuitry makes it simple and compact and provides more flexibility as in future if any change is required then only by changing the program its functionalities can be changed.

Although low cost standard processing hardware was chosen, it performs well and is capable of doing its work efficiently.

It has caterpillar type wheel arrangement. It helps in the movement of the vehicle in rough terrain. Also its turning radius is very small.

Future Scope

First, it would be useful to add a function in sound detection to detect regular banging. Indeed, in disaster area, sometimes victims are banging on wall or on ground because they can’t shout. Moreover sound propagates itself better in structure than in the air. So if the robot could be able to detect regular banging it will have one more useful function for human detection
