wireless bomb detecting robot with camera using PIC18f4520

hi everybody,
i'm doing a project on pic based wireless bomb detecting robot with camera, can anyone give the block diagram for the project and also the circuit diagram . If there is any link to look into so that i can learn more about this project. please let me know. Please reply ASAP.And any other information regarding this project please let me know.
thank u...

With sensors for "smelling" explosive material throught air ?


You mean something like this :

Or maybe you should get one of this (this dont have needs for battery recharge, just one frankfurter per day) :

Meanwhile, its nice to read this about sensors :

Sensors for Hazardous Compounds
https://www.blogs.uni-mainz.de/fb09...ors-for-the-detection-of-hazardous-compounds/

Many illicit and hazardous compounds cause vapor traces in the air. By use of microbalances (QMB) with specifically designed coatings we are able to detect such volatile traces in the ppm – ppb range. Research focus is on the detection of triacetone triperoxide (TATP), a very dangerous but easy-to-make explosive. Ambitioned but unaware amateur chemists as well as people with malicious intentions handle this compound leading to several fatal incidents a year. Consequently, early but easy detection of this explosive is highly desired.




The core element of a quartz microbalances is a piezoelectric quartz which is electronically brought to oscillation. Its resonance frequency is mainly influenced by the mass of this oscillator. As the alterations of the oscillating mass result in direct changes of the resonance frequency, it is a mass-sensitive sensor like a balance. Deposition of compounds from the atmosphere on the surface changes this mass and hence the resonance frequency. We are using systems with a fundamental frequency of 200 MHz. The high frequency offers fast kinetics and suitable sensitivity for continueausly working sensors.






Often thise kind purpose robots are NOT wireless, they are controlled over wire, also sometimes power goes through cables also. At that area RF jammers are used for wide spectar of RF frequencies to prevent remote activation via GSM, WiFi,....
