why do u need a robot that senses fire if its just going to sense then wats the use of a robot , yes if u need heat sensors on a robot to do a specific job then its ok

yes photovore may work but how the hell are u going to put out the fire is ur bot going to carry water and a pump

if yes then u have got quite a hell of a job to do especially powering those pumps

Do a Google search for Fire Fighting Robot. There are several comp's accross the states and I assume this is what you are trying to do.

Your looking for something like the TPA81 Thermal Sensor Array, which is pretty expensive (around $115).  Do a google search for suppliers.

For carrying and dispensing water you might want to look at the pumps used in water cooling computer systems.  I would imagine one could be hacked with an H-Bridge or ESC to turn it on and off as needed.

Also pond pumps. They have plenty of 6V and 12V low currant pumps that can shoot water straight up a couple of feet.

i dont know,but i dont think that carrying pump is that hard,i think i can find smth small and good for carrying.
my 1st and biggest problem is sensing that fire.im not sure that smoke works or not but a sensitive sensor for sensing heat or light can work.all heat and light sensors that i know are havnt that quality and ability for sensing fire from distance.i should search more about it  ::)


i also have another idea,i mean one of my friends told me look for the tecnologi of infrared cams.it can work but i think it is too expensive.do u know smth about infrared cams?


no one here doesnt work in this field?i mean that there isnt anybody that made smth fire fighter???

thanks
