Fire-fighting Robot finds flame in fourth room it searches

[stevespielberg]

So this is from 1998? Impressive. What are you up to now? I find this incredibly fascinating.

[depender1]

After extinguishing a fire in a room it will sing a congratulation song?!? O.o

[depender1]

lmaooooo this thing is gonna extinguish a huge fire in my room with THAT FAN?!?!? HAHAHAHAHAHAHAHAHAHAHA

[poopinitup]

I hope you respond to this after such a long time! What kind of degree and graduate degrees are good to do this kind of stuff?

[rasmasyean]

@poopinitup This type of stuff is a mixture of Mechanical Engineering, Electrical Engineering, and Computer Science. I think Carnegie Mellon has a "Robotics" degree program that prolly mixes these curiculums. Otherwise, you'd prolly have to pick one and pic some courses cross major.

[thejapz]

@rasmasyean it's called mechatronics :D

[j3k2006]

@poopinitup Mechatronics Engineering

[tahiman2]

@poopinitup i m sorry to intefere......but is mechatronics an appropriate course for robotics

[9n8a7]

hi i found ur project is very intresting

could u plz provid me with circuit diagram

thnx ....

[dannyc1803]

That is a awesome robot but i do belive that it will be a long time before robots replace us firefighters. judgement and gut inst. have alot to play in firefighting and life saftey

[Sugardude]

Indeed, but it's nice to know that a firefighter can rely on a robot for those more life threatening situations. I don't think it's a question of replacing men, but allowing a disposable machine take risks instead of sending a person...

[sckryde]

thats cool..

you know what would be cool?

some type of thermo sensors as well as air toxicity sensors.. it would allow the machine.. to define the most critical areas

[rasmasyean]

Those are good ideas. They do have a UV Tron sensor that can allow it to detect a flame in the room by just passing through the hall wihtout having to enter it and point in. I don't think they would use any toxic fumes in a consted like this, but I'm sure a future real fire-fighting robot will have one definately! ;)

[sckryde]

i was not aware that fire emits a U.V frequency..

i also think it would be vital for the control operator to have a chemical and fume detection system together with the thermal sensors and other optics. it could increase survivability probability and help keep the fire fighter out of danger.

[amando96]

why so many ir sensors and ping? all you need is like 4 at the max...

at the moment i'm using one! and it works fine... have to make some more though...

[rasmasyean]

It's just one of the demos of what the robot can do. If you look at the description, it's not built for "fire-fighting contests". If you are interested in details of the overall project and want to learn about the sensors, email me and I'll send you the paper (unless you want to search the libraries for it).

[Cowardlyman]

Lmao, it went to every other room first. . Hahahahahaha

[patelk0524]

the house would have been burned down by now byt i bet it could be made faster

[TheArrantLuxury]

Haha, excellent music at the end there. What time of algorithm do you use to navigate the maze? DFS?

[rasmasyean]

Thx! I thought it was funny because I made everyone in the lab shut up for the whole take! haha

Nah, just a real simple if-then sequence. Moving from one state to the next. The layout is known already. It just has to find the candle in the room it detected it in.

cable

[Dadooo0]

Hi, what kind of odometric sensors did you use, for this purpose?

[rasmasyean]

Old ones..."BEI PM2-120" optical quadrature encoders. Basically inside it's a slotted disc I think. Like old ball mice. But it's more accurate (120 counts per channel). And it outputs like 5v or something (i forgot) per channel (2).

[Dadooo0]

i see, thanks for your reply !

[Rimber6]

Lol, so they couldn't give it some heat sensors?

[gangifreek17]

aww its cute but u need to make it find fire faster

[sintvaffel]

BAD thing. my house could have burnd down befor that thing even find it's way in.

[rasmasyean]

haha. We're no where near real-world operation of such a device yet, unfortunatetly. But they do have much faster and more capable ones these days and hopefully soon it will get your slippers too! ;)
