The project aims in designing a War field robot which is capable of detecting human beings and land mines in its path and which is wirelessly controlled through PC using Zigbee technology. This robot also shoots using the laser light. It is a very low cost robot used to monitor the Warfield. The robot can be moved in all the directions using the PC wirelessly and automatically do the respective actions according to the sensor input.
Zigbee is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices, Zigbee devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one device to another. This technique allows the short range of an individual node to be expanded and multiplied, covering a much larger area.
The controlling device of the whole system is a Microcontroller. Whenever the user presses a button in the PC, the data related to that button is sent through Zigbee module interfaced to PC. This data will be received by the Zigbee module in the robot system and feds this to Microcontroller which judges the relevant task to the information received and acts accordingly. This system also can detect fire and sprinkling the water automatically.
