Problem Statement
A fire in a residential building is a common and critical emergency in any big urban area. Apart from the damage it does to the building, there are often people stuck inside whose lives depend on how quickly they are found and rescued by the firefighters. Sometimes, when the emergency services arrive at the scene, the entry to the building is already blocked by fire. The first question that a firefighting crew has, is how many people are inside and where they are. If the entry is blocked, or there are other complications, the search and rescue procedures can only be started after it is safe to enter the building. This delays the rescue and decreases the chances of people trapped inside surviving with every second. Often this leads to either firefighters entering the house even when it is still dangerous, or people not getting rescued in time.
Our solution is to come up with a robot (or another suitable system) that helps to locate survivors/people inside a building on fire. This would be a tool used by firefighting crews, that would decrease the total time it takes to rescue a person and decrease the risks for firefighters themselves. Therefore, the robot must be heat and fire resistant to be deployed as soon as emergency services are on the scene, without spending time on decreasing the severity of fire, before beginning the search and rescue operation.
Objectives
This project will focus on designing a robot that can be used in a fire to find and help rescue people. At the end, the robot should have the following design features:
- The robot must be sturdy and fire resistant to endure the harsh environment during its operation.
- The robot needs a navigation system to find a way through the desired area.
- The robot needs multiple sensors that give intel about the environment in order to find trapped people inside.
- The robot must use a way of transportation that is suited for fires. It should be able to step over or avoid fallen debris that is produced by the fire.
- The robot must be easy for firefighters to use.
- The robot should be as small as possible for it to travel through all locations in a fire.
Given the purpose of the robot as well as its objectives, this project will focus on the design. Additional prototypes could be developed but is not the focus for now.
Users
The users are mostly the firefighters using the robots to locate people in a burning building. They need to be able to quickly and easily understand where the robot has found people. The stakes will be high and time is very much of the essence. Another user group is the people who are in need of saving. If they are still conscious, they need to understand the robot is trying to help them, they should remain in the place where the robot found them as long as possible for the firefighter to easily find them. Other helpful tips like stay low to the ground to avoid breathing in smoke can be given to the people in need.
What do the users require
The firefighters require, as mentioned, an easy to understand system. They cannot waste precious time on trying to figure out the cues the robot is giving because this will only interfere with the saving process instead of expedite it. They also need a product that is robust and will not break down in time of crisis, because that would again be wasting time. Another important factor is of course that the robot should not overlook people that can still be saved and should make clear that the firefighters should still keep their eyes peeled for potential victims it might have missed to avoid a mistake that would cost a life.
Furthermore the professionals need to be properly trained in the use of any given robot, but also in the use of robots in general. An idea proposed in the (now quite old) [After Action Report to the Joint Program Office: Center for the Robotic Assisted Search and Rescue (CRASAR) Related Efforts at the World Trade Center, section 4.3] is to provide a prototype that the personnel can train with, thus both giving them a head start in training and granting valuable feedback to the designers of the robot.
According to [Frauke Driewer et al, 2005 TODO] some of the most important jobs of a robot for firefighters are:
· Exploring and going into dangerous places
· Detecting the location of people
· Detecting dangerous areas and hazardous materials
· Sending information from the scene
And the most desired features to be included were
· Data transfer
· Working efficiently at high temperatures
· Climbing stairs
But Moving and acting without exact instructions and Interacting with the rescue team on the scene were rated as less important features.
In [Harbers et al, 2017 TODO] we can see some of the most important ethical dilemmas that were derived based on conversations/workshops with professionals (in the field of SAR):
1. “Should SAR robots be employed when they might help saving lives, but their application might also lead to casualties?
2. Should one develop SAR technology that is intended for peaceful purposes even when it has clear military potential?
3. Should one replace infield workers by robots if that leads to suboptimal performance?
4. To what extent should information collected by robots be processed to make it more digestible, at the risk of losing or misrepresenting information?
5. Should one deploy robots, knowing that this may raise false expectations and runs the risk of degraded performance?
6. Should one deploy robots that may yield responsibility assignment problems?”
Thus for a robot to be deployed in a live situation it is almost necessary that the developer resolves these dilemmas, either generally or at least for the special case of the robot. Or else the users (specifically firefighters) might not be able to use the robot in good conscience.
The people in need of saving need a robot that does not scare them. It should be immediately be clear the robot is their friend and if instructions are given to these people it should be very clear for them to understand even if they cannot see or hear which is quite likely in a burning building.

Literature review/State of the art:
Summary/Relevance to topic:
A big issue for firefighting robots is the heat radiated by the fire. There are existing ways for increasing the resistance to heat, used for example with water cannon robots. However, the current method requires a lot of water, increasing the weight of the robot by a lot. This obviously reduces the mobility of the robot a lot. This paper aims to find another way to make these robots heat resistant, using much less water, by implementing an exterior cover. This paper goes into the design specifics of this cover. Even though the aim of our robot is not to assist in the firefighting itself, but rather locating potential survivors, this robot obviously still needs to be heat resistant. Therefore, this design proposal might also be valuable for our robot design.
Robot-aided human evacuation optimal path planning for fire drill in buildings - ScienceDirect
Summary/Relevance to topic:
This paper researches algorithms to assist humans with evacuating, by calculating the fastest routes out. In our robot design, we would like to implement not only the locating of potential survivors, but also a fastest route for the firefighters to reach this person. A similar algorithm as that discussed in the paper can be implemented in our design as well.
Summary/Relevance to topic:
Here, rather than the use of for example heat sensors, AI deep learning and machine vision is used top detect fires. This already works with a very high accuracy. Extending this, the machine vision could potentially also be used to differentiate between fire and potential survivors. This might be more accurate than using merely heat and motion sensors to locate people, thus improving how well our design would work.

Summary/Relevance to topic:
This paper goes into the GUARDIANS robot swarm, which is designed to assist firefighters in searching big warehouses for survivors to save. This is very similar to what our design aims to do, although we would like to apply this in housefires/other smaller fires as well, not just large warehouses. However. a lot of the technologies discussed in this paper, such as the wireless communication system, are very relevant to our design.
The role of robots in firefighting | Emerald Insight
Summary/Relevance to topic:
This paper goes into the state of the art, as robotics in firefighting is a fairly new technology. So far, the most prevalent technologies include: all-terrain vehicles to assist the actual fire-fighters with getting to and operating at dangerous locations, also giving the firefighters a better overview of the situation by using sensors, and drones that are either equipped with fire extinguishing materials, can hold up a hose (both used for high up buildings), or to again create more awareness of the situation for the firefighters. This state of the art review can help assessing what elements of our design already exist, what needs to be improved, and what is still missing.

The paper identifies key human-robot interaction research questions and emphasizes the need for human-centered advances to ensure effective rescue operations.
The Application of Multi-agent Robotic Systems for Earthquake Rescue.
Summary/Relevance:
Rescue robots are used in a variety of situations, which include earthquakes. In relation to fire rescue robots, a lot can be learned from earthquakes since the environment is very similar. This paper covers various aspects of a rescue robot, such as the structure of multi-agent control systems, methods for searching victims, path planning and search algorithms. Many of these aspects can come in handy for the future of rescue robotics.
Thermal and structural analyses of firefighting robot.
Summary/Relevance:
A robot that has to endure harsh environments as well as rapid environmental changes requires materials that are well suited for these situations. The paper goes over a structural and thermal analysis that evaluates the performance of a robot that can be used in, for instance, a big house fire. The robot was designed with materials like galvanized steel as the main plate, cubic boron nitride coating for non-flammability and silica aerogel for thermal insulation. Results show that that after 1800 seconds, the inside of the robot only had a temperature change of 2 degrees. It can be concluded that these materials are very well suited for its application and can make sure that all systems on board of the robot can operate under harsh conditions.
Flying dragon robot used to help extinguish fires | frontiers
Summary/Relevance:
This paper delves into research about making a remotely controllabe firefighting robot. The idea is of course that less human fire fighters have to go into the dangerous fire and to instead send robots. How to let the robot move, what the optimal nozzle size is for the best water thrust, new waterproofing techniques, and a larger movable range of the nozzle unit are discussed. These things are relevant to our robot especially if we are able to encoorporate a water tank to help locally extinguish fire around a person, which would of course improve the functionality of the robot.

Summary/Relevance:
This paper considers some ethical concerns surrounding SAR robots. Issues like the level of robot autonomy, laws surrounding robot design and behavior, but issues with the human response to the robots and who is responsible for the actions of the robot.
Improving the SAR robots feedback and interface
Summary/Relevance:
This paper summaries four studies done on what type of feedback and interface a SAR robot should give/have to be the most trusted and best understood. This is very important because having a robot that no one understands or trusts is virtually useless and will only add confusion and fear to an already terrifying situation. The main finding is that multi-sensory interfaces (having e.g., visual, olfactory, and audio feedback) can be very beneficial and have minor effects on the cognitive load. Or in other words you should exploit the redundancy gain.
Robot competition (RoboCup) to locate victims
Summary/Relevance:
This paper shows the results of a robot building competition that had the main goal of building a robot that locates victims and determines their health status. It discusses how the different teams tackled this challenge and the outcomes of their strategies. It gives an overview of a lot of different and unique ways to locate victims in a maze situation (which is similar to corridors in for instance a hospital) and how effective it was. We could use this to help inform and get inspiration about our decisions about building a robot that locates people in a building.
Process of human behavior in fires
Summary/Relevance:
This paper aims to give an overview of the behavior people display during a fire. It does this by breaking the process down into phases and describes what factors are relevant for an individuals response. For our robots design it is important to understand how people respond in a fire to antipate the interaction the human robot interaction.
