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.

Transportation (Responsible: Storm):

Week 2: Research transportation methods for the robot

Deliverables: List of transportation methods with summaries/ pros and cons

The robot that is going to be designed in this project needs a way of transportation. Robots in general have a lot of ways to transport like walking, rolling or a snake like movement. To determine what is best in the case of a fire rescue robot, pros and cons of each transportation method are needed to evaluate the best possible option. It is also important to keep in mind the environment that the robot operates in, since the robot needs to be able to face a challenges in encounters, such as fire and falling debris.

Walking

A robot can achieve a walking motion if it is equipped with legs. Examples of such robots can be seen below and are developed by Boston dynamics. These robots use either two or four legs, depending on the application. But there also exist robot with more than four legs, to increase stability.

Boston dynamics robots

Pros:

• A walking robot can be quite fast and versatile, which enables the robot to navigate efficiently through the burning environment.
• Legs can be made from strong and durable materials that are fire resistant.
• Having a walking motion makes adapting to the environment quite easy. Stepping over falling debris is possible as well as walking over direct burning surfaces.
• The body of the robot is raised above the ground by the legs, protecting the important electronics and equipment on board from burning surfaces.

Cons:

• Creating a walking motion in a robot is quite hard on both a mechanical and electrical level.
• The legs of the robot come with certain dimensions that could make the robot bigger than desired. It will be hard for firefighters to carry such a robot to the scene.
• A leg could get damaged in the action, making the robot potentially completely unable to move.
• Development of a walking robot will be more costly.
• Weight distribution is incredibly important and it could bring risks of falling over. This would need to be perfect in order for the robot to do its job without problems.

Rolling

Other than walking, a lot of robots use wheels to transport. There are mainly two ways to do this, namely with wheels or tracks. Having wheels makes the robot able to move very fast, like a remote control car. It is needless to say that this way of transportation is quite efficient, fast and applicable in many situations. In the figure below a robot can be seen that was already designed to do similar tasks that this project requires, which shows that wheels can be a feasible transportation method. Besides wheels, a robot could have tracks. This is similar to vehicles like a tank. Tracks can support a lot of weight and can travel on a lot of different surfaces. Implementing a rolling like way of transportation has a lot of room for innovation and can be achieved in a lot of different ways.

A two wheel rescue robot

Pros:

• Rolling can be fast and reliable.
• Using the right materials, wheels or tracks could be able to withstand burning surfaces, thus being able to drive through direct fires.
• Rolling is very versatile and can get the robot all over the area very fast.

Cons:

• Having wheels would bring difficulty with clearing big obstacles, like fallen debris. It could get stuck or unable to move a certain direction since it is blocked. Tracks could be better to solve this problem.
• Wheels and tracks are prone to wear and tear, which would increase maintenance.
• Such a system requires a lot of energy, so the longer the robot needs to operate, the bigger the battery it would need on board.

Snake like movement

Another way that a robot can move itself is by recreating the movement of snake or worm. This way, the robot can be designed to reach narrow places. Although this method is less common that the previous two methods, there is still a lot of research involving this transportation system.

Pros:

• It can reach small and narrow places that are potentially obstructed by the environment, which other robots/firefighters would not be able to get to.
• Can easily adapt to the rescue area, going over fallen debris or navigating around obstructed paths.
• The size of the robot can be changed quite easily to fit the given fire hazard, by connecting multiple robots together. (If this is feature that the robot has).

Cons:

• This is hard to design since it is less commonly used in robots.
• It would require a lot energy, posing the same problem with have a rolling system explained earlier.
• The robot will be fully on the ground, therefore, the robot must be well protected from direct fires and should be able to be in a fire for longer periods of time.

Flying

Another method that can be considered is a robot that does not drive or walk, but can fly. A drone could potentially be used to fly through the area searching for people. Drones are becoming more and more popular in all kinds of applications, therefore, a lot of different drones already exist and there is a lot to choose from. Drones are already being developed to assist firefighters. One drone could withstand 200 degrees Celsius for ten minutes without losing any functionality (https://www.advancedsciencenews.com/a-heat-resistant-drone-that-can-fly-into-fires/). This is of course not enough, but shows that heat resistance can be achieved in a drone. However, flying with drones in an enclosed burning area can bring some problems with it, as can be seen in the pros and cons below.

Pros:

• Drones are fast and versatile.
• Drones can avoid flying through direct fires because of its mobility.
• With drones, locating people can be a bit easier since they approach the scene from above.
• A drone can enter a building from many entry points, like doors and windows.
• Drones can also fly over the burning area, assisting firefighters to locate fires all around the perimeter. So a drone is not only for rescue, also for general intel.

Cons:

• Drones are usually not fire resistant, so different materials have to be used, especially for the propellors.
• Flying a drone inside for instance a house can be very hard and precise movements need to be made to avoid hitting something. Either an automated system would need to be developed or it can be remote controlled, but firefighters would need to be trained to fly a drone.
• The effects of the propellors that come from flying with a drone can either be good or bad. The wind could calm down the fire right below the drone or it could enhance the fire. More research/experiments would need to be done for this.

Transporting the robot

Before it was seen in what way a robot can move itself, but that is not the only thing that needs transportation. The actual robot needs to be delivered to the designated area, thus needing transportation. Firefighters bring a lot of equipment to the scene and have big trucks to store al their stuff. It is only the question if there is space left for this robot (This will become more clear after the interview). Therefore, it is important to keep the size of the robot as compact as possible to be easily transported and carried by the fire department.

If we take a look into other applications of robots, like the police department, a lot can be learned from them. Bomb detecting robots are commonly used to protect police officers against dangers. These robots are part of a special division inside the department known as bomb squads. The robots are brought on scene in an extra vehicle with more equipment. It can be seen that this is not particular efficient for the fire department. If they would need an extra vehicle to transport this robot, more people and money is needed for more operations. Thus, a solution is needed that figures out how a robot can be deployed when it is needed.

Conclusion

There are a few different ways a robot can move itself, like walking, rolling, slithering or flying. Each of these methods has its ups and downs and can be considered in the design. It is a matter of discussing which method would be the best fit for our requirements and how this method influences the other components of the project. A solution for deploying the robot by the fire department is also needed.

Literature review/State of the art:

Novel exterior cover design for radiant heat resistance of firefighting robots in large-scale petrochemical complex fires | ROBOMECH Journal | Full Text (springeropen.com)

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.

Fire Fighter Robot with Deep Learning and Machine Vision by Amit Dhiman, Neel Shah, Pranali Adhikari, Sayli Kumbhar, Inderjit Singh Dhanjal, Ninad Mehendale :: SSRN

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 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.

Ethical concerns about search and rescue (SAR) robots

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.

This article provides another insight into heat resistance for robots and how it behaves. This article is a good source for preparing a test plan for our robot’s thermal-protective shield/cover. Not only a heat shield is designed, but it is also tested, and these tests are what makes this article so valuable within this project.

RoBoa: Construction and Evaluation of a Steerable Vine Robot for Search and Rescue Applications | IEEE

Summary/Relevance to topic:

The article gives a good insight into Vine Robots being used in search and rescue operations. The design proposed in the article can be used within our project, if we choose to base our robot on Vine Robot model. However, a lot of work still needs to be done to make the design fit for extreme thermal conditions (if it is possible).

An Arduino Uno Controlled Fire Fighting Robot for Fires in Enclosed Spaces | IEEE

Summary/Relevance to topic:

The article contains a basic design of a low-budget firefighting robot. If we decide to make a prototype of our robot, this article will be useful, as the Arduino system is indeed affordable and firefighting-robot mentioned in the article shares a lot of properties with a SOR robot for fires, that we have in mind.

Van Wynsberghe, A. A method for integrating ethics into the design of robots. Ind. Robot. 2013, 40, 433–440.

A paper about how to integrate ethics into robot design. "The approach for including ethics in the design process of care robots used in this paper is called the Care‐Centered Value Sensitive Design (CCVSD) approach. [...] In this paper, this approach's utility and prospective methodology are illustrated by proposing a novel care robot, the “wee‐bot”, for the collection and testing of urine samples in a hospital context."

Different subjects to focus on (for technology):

communication apps (eg. make contact with (grand)children easier)

entertainment (eg. the reading thing mentioned earlier)

services that are getting more and more digitalized (such as physical banks disappearing)

general approach to helping with technology (probably hard to realize)

rather than thinking of some device to help the problem, we could potentially also just focus on writing a paper on the issues that come with this, reasons for it, possible benefits of elders using tech etc. (as there are a lot of studies available for this)

assistive technologies (ones that for example improve healthcare)
