BFG Firefighting Edition Overview
- Simulator for Fire Officers
- Goal
- Virtual training for fire officers
- Trains leadership skills
- Minimizes casualties (training/emergency)
3
Firefighter AI
- Goal
- AI needs to mimic reality
- Virtual firefighters must act like real
firefighters - Needs to calculate paths without lag
4
On the Evaluation Sheet
- Please write down 3 hazards or safety procedures
to follow during a fire - (In a firefighters point of view)
5
Common AI search algorithm A
- Informed search algorithm
- Example of best first search
- Finds a path to follow based on estimation
- Uses Priority Queues
- Priority is given by f(x) g(x) h(x)
- f(x) priority
- g(x) cost of path so far
- h(x) estimated cost of path to the goal
6
Uses of A in BFG
- Pros
- Provides quick search of how to travel through
fire - Cons
- Does not properly mimic reality for training
purposes - More is involved in firefighting than estimating
best paths to travel in a fire
7
Supposed current implementations
- Keeps track of but does not act accordingly
- Smoke density
- Heat
- Flawed AI
- Each firefighter blindly enters fire
8
Precautions in Firefighting
- Common sense
- Be wary of extreme temperatures
- Dont walk blindly (Move under smoke)
- Keep track of air supply
- Cut off fuel for fires
- Shut windows and doors to prevent air flow
- Isolate any possible fire sources
9
Precautions in Firefighting (2)
- Feel doors for heat
- If hot or smoke present, do not open
- Keep fire away from dangerous chemicals
- Gasoline
- Safety is a priority!
- Rescue victims, but ensure safe paths first
10
Implementation
- Divide environment volume into cubes
- In each cube, provide
- Smoke density
- Temperature
- Present gases
- Etc
- Ensure that lookup works in constant time
11
Implementation (2)
- User (Fire officer) tells firefighter the goal
- Ex set up ladder, extinguish fire in living room
- Firefighter generates tasks automatically based
on safety procedures - Priority queues
- Each automated task will perform under A
12
Demo status
- Basic user AI if any
- Monitor smoke densities/temperature/air supply
- Firefighter will move in a 3D environment with
some basic interaction
13
Discuss Additional Fire Safety Precautions
- Are there any fire safety precaution steps that
you have thought of that I did not mention?
