Who is making your robot ?

i'm building a robot car which can search for human body in remote places such as jungles,etc.

which jungle are you going to test it??
or, are you planning to test it at all, if you make it??
is that an academic project?
Is it for any competition?
What is your budget?
When do you want to finish the robot?
Why is it urgent?

first of all...
It's for a competion on wednesday a.k.a 22nd december.
jungles, disaster hit buildings ETC..
my budjet is around say Rs. 2000

I hate to say but huge mismatch between expectations and budget :) .

A human detector in jungle/anywhere would be i say consist of atleast a FLIR camera with a lot of processing power, a FLIR costs more than your Budget in USD.

Anyhow you can rig a Quad opamp to a microphone and a pir sensor to a OR gate ... sound or motion will blink led , if you want it to stay on use a latch.

I hate to say this!! But do you think that you can complete your project in such a short notice...22nd dec is round the corner. Also there was someone else who had raised similar topic probably for similar competition. Kindly check that ppost.
