=== Project Statement ===
=== Project Statement ===
Wildfires are occurring throughout the world at an increasing rate. Great droughts in various regions across the globe are increasing the probability of wildfires to occur. National parks deal with major wildfires multiple times a year. Areas devastated by wildfires are mostly devoid of life, while potentially still having an extremely fertile soil containing all the biomass left after the fire. Artificial reforestation can accelerate the natural process which accounts for the regrowth of the forests. This process might be enhanced by means of technology, for example by deploying robots that plant seeds of saplings in these areas. <br>
This project investigates the possibility and potential of utilizing robots to restore these devastated areas to their former glory. In order to investigate this possibility, a thorough analysis of different methods of reforestation is made first. By comparing methods of reforestation a great deal can be learned about which negative aspects of the current reforestation methods should be enhanced by a new reforestation robot. Also, this analysis will explore if a new method of reforestation is needed at all. Beyond this, two case studies are investigated. These case studies show how reforestation and forest fires are currently being handled. The case help studies help to get a better understanding of what the robot should be able to do and what it ought not to be able to do and thus help to define design criteria. <br>
Finally, multiple preliminary designs are made for the seeding mechanism of the robot which would accomplish all necessities found during the analysis of the different reforestation methods and which follows all the criteria discovered in the case studies. Out of these designs, the one ranking highest on the criteria unraveled during the literature review and case studies is chosen to be the best suitable seeding mechanism for the future robot.  Additionally, a design is made for a user interface that will allow the staff of a national park to control a swarm of robots in a user-friendly and non time consuming way. Lastly, some suggestions for future research are given, in the topics of what other crucial functionalities the robot requires, how the robots would be able to communicate among themselves during operation, and how the robots would be able to communicate with the user in case of unforeseen circumstances. To conclude, this project aims to assess the necessity of a robot to rebuild a forest in a national park after a forest fire, discover the functionalities such a robot must have and design a user interface to control such robots based on the gained information.

<sup>*</sup> The current division of task is a rough estimate for the next 7 weeks. New tasks may pop up or task division may be rotated, and is hence subject to change during the progress of the course.


=== Approach ===
=== Approach ===
The problem will be approached by a design question. What is the best design for a robot to combat deforestation which will be build modular so that it can be implemented for other purposes with minor changes. The first 2 weeks the approach will primarily be sequential, as user analysis, use cases and requirements/preferences/constraints need to be done sequentially before the rest of the project can start. Once this is over, the project will run in a parallel fashion where building and modelling will happen simultaneously.  
The problem will be approached by means of a design question. What would be the best design for an effective seeding mechanism which can be used in a mobile robot deployed in a reforestation operation, and how would this robot be controlled? The gross of the project is carried out sequentially as each subject builds further upon the conclusion reached during the last subject, which is represented in the structure of this Wiki consisting of several subpages corresponding to these subjects. Albeit that the project is carried out sequentially, within each sequence several tasks are divided such that they can be carried out in parallel by different group members. During the last phase of the project, when the major milestones have been finished, the project wrap up consists of several small independent task which will allow us to abandon the sequential structure which was necessary during the other phases and carry out these tasks in parallel to gain in time.

== Literature Review ==
The literature review was divided into 5 subcategories, the results of which will be extended below.
=== Modularity ===
Modular robotics is a useful tool in the design of robots for in-field applications, as building a functional specialised robot from scratch is a time-consuming and cost-intensive process. If a modular design approach is taken, the costs of designing a robot could be severely reduced as one general robotic platform with some general functionalities would serve as the starting point, upon which modules can be placed to give the end-product the desired capabilities. A drawback of this modular design method, however, is that the design space will expand explosively due to the seemingly limitless possible configurations the robot could have <ref name= "Mod Robot"> Farritor, S. & Dubowsky, S.. Autonomous Robots (2001) Volume 10, pp57-65. “On Modular Design of Field Robotic Systems”. https://doi.org/10.1023/A:1026596403167 </ref>. However, this design space can be brought to proportions by severely reducing it, by placing the constraints which arise from the task to be completed by the robot onto the possible configurations <ref name= "Mod Robot" />. By doing so any and all designs with but a singular deviation which would compromise the execution of the task are immediately discarded in the earlier stages of development.
Some examples of robots which implemented a modular design and with similar environmental working conditions as our to-be-designed seeding robot include the Small Robotic Farm Vehicle <ref> Bawden, O., Ball, D., Kulk, J., Perez, T., & Russell, R.. Australian Conference on Robotics and Automation (2014). “A lightweight, modular robotic vehicle for the sustainable intensification of agriculture.” </ref>, the 4-wheel steering weed detection robot of Bak and Jakobsen <ref> Bak, T., & Jakobsen, H..

These robots have in common that they are mostly based on a singular platform, suspended by wheels for locomotion, upon which several modules (e.g. sensors, mechatronic arms, pay-loads, other deployable robots, etc.) can be placed to increase functionality.
=== (Semi)-Autonomous Cars ===
The patent on remote control systems granted to Mitsubishi Electric Crop. By the US government. This document is a thorough description of how remote control systems work, if we decide to make our vehicle remote controlled all the info we need is in here. But it is incredibly lengthy and written in a way that is not pleasant to read, so use it as a last resort. <ref> https://patentimages.storage.googleapis.com/eb/4b/ce/ba560b94ae5c1a/US5554980.pdf </ref>
This 2 page article is a statement from Elon Musk, CEO of Tesla, about his predictions for autonomous cars in the near future. It shows his vision, which is directly linked to his companies (one of the biggest on this market) vision. <ref> http://www.oharas.com/ET/elonmusk.pdf </ref>
To get our car driving smoothly, we will probably utilize a remote control, meaning that it will be very closely related to a remote controlled toy car, to which this doc. is the current active patent. It shows the state of the art radio controlled toy car technology currently available. <ref> https://patents.google.com/patent/US4457101A/en </ref>
A guide to help us control a servo motor with our computer, as a servo motor is the most likely option if we want our car to drive without outside help. <ref> http://www.instructables.com/id/How-to-Dynamically-control-a-servo-or-motor-throug/ </ref>
A short article on the workings of servo motors, the main two interesting reads are the control of the servo and the different types, as we will have to chose one if we opt to use servo’s to drive our car around. <ref> https://www.jameco.com/jameco/workshop/howitworks/how-servo-motors-work.html </ref>
Even though this site is a webshop, and not a scientific article, it shows what technology we can buy within a respectable price range and thus shows what we do not need to make ourselves. Before we start thinking about how to make a part of our robot, lets first check what this shop has got. <ref> https://www.tinytronics.nl/shop/nl </ref>
=== Sensors for prospecting/evaluating ground ===
Evaluating the soil the robot is on can be the defining factor whether it is worth it to plant new seeds in the ground, since an infertile soil will not create a new healthy forest. The design of the robot would benefit from such sensors, since it can utilize this information to determine where to plant the seeds.
Currently the soil can be read with a multitude of sensors. The most simple, but ineffective for our robot, sensor would be to use a simple plant and determine whether the plant shows sufficient growth. A lot of information can be obtained from the plant, like the salinity, nutrients and available soil moisture.
This is however very inefficient and not desirable for our robot. An alternative would be to use moisture sensors to determine the amount of water in the ground, since water is a critical component for a plant to grow.
Further sensors include NIR reflectance sensors. These sensors can accurately measure the organic matter within the soil. This leads to an accurate picture whether the soil is fertile enough to plant seeds.
Vis-NIR sensors can also determine the amount of nitrogen and moisture in the soil. Which leads to an even more complete picture of the soil.
Humidity in the air can also help determine whether the area is suitable. An RH sensor based on a Bragg grating can determine the relative humidity accurately. The optical fiber used to determine this can also house temperature, pH, pressure and more sensors. This results in a quite complete picture of the environment above the soil and can help determine the suitability for planting the seeds.
The robot can also be used in predetermined areas. Forest fires, for example, increase the nitrogen in the soil and in most cases the amount of carbon is also increased. This results in a soil that is suitable and fertile enough to deploy our robot on.
=== Drilling/plowing/seeding mechanism ===
=== Current deforestation and combat methods ===
Deforestation is clearing Earth’s forests on a massive scale, often resulting in damage to the quality of land. The world’s rain forests could completely vanish in a hundred years at current rate of deforestation. Consequences of deforestation are the loss of habitat for millions of species and climate changes. The most feasible solution to deforestation is to carefully manage forest resources by eliminating clear-cutting to make sure forest environments remain intact. The cutting that does occur should be balanced by planting young trees to replace older trees felled. The number of new tree plantations is growing each year, but their total still equals a tiny fraction of the Earth’s forested land. (Geographic, 2015) <ref> Geographic, N. (2015, April). Deforestation. Retrieved from National Geographic: https://www.nationalgeographic.com/environment/global-warming/deforestation/ </ref>
Rehabilitation of deforestation areas can have different steps. It can include anti-erosion works, projects for slope formation and protection and reforestation. The prototype will focus on reforestation. The forest service takes into account the type of vegetation that has been burned, the success potential of natural regeneration of trees and the general conditions, and, accordingly, shall proceed, or not, to artificial reforestation of burnt areas using native species. The purpose of reforestation is the creation of new forests, the renewal of mature forests and the recovery of degraded forest ecosystems while ensuring natural regeneration or artificial intervention (seeding or planting) for production purposes and the protection of soils. The cost of reforestation in the last 8 years was enormous due to many manhours. (Christopoulou, 2011) <ref> Christopoulou, O. (2011). Deforestation/ reforestation in Mediterranean Europe: The Case of Greece. Soil Erosion Studies, 3-30. </ref>
This website reviews many different ways for reforestation. Almost all methods are based on man work, people are physically present and are planting the seeds themselves: direct seeding. One method that is currently used that does not involve a person physically being where the seed is planted is called aerial seeding. This method plants new seeds using planes and helicopters. This method is much more efficient than being physically present on the ground but is generally outside the budget of most reforestation projects. (David, 2015)<ref> David. (2015, January ). Reforestation Methods Reforestation Projects. Retrieved from Reforestation: https://reforestation.me/reforestation-methods/ </ref>
Seeds of different species have different optimal depths for sowing, with some growing best if they are buried a few inches deep in the soil, while others, including many grasses and herbs, need exposure to light to germinate and so need to be on the surface. A rule of thumb when growing vegetables and grains is to sow the seed at a depth of one to two times the width of the seed. If seeds of one species, or a mixture of seeds of different species with different needs are randomly mixed in a larger seed ball, at least some of the seeds should be in the optimal position for germination. This optimizes reforestation. (Goosem & Tucker, 2013)<ref> Goosem, S., & Tucker, N. (2013). Repairing the Rainforest . Cairns: Wet Tropics Management Authority and Biotropica Australia Pty. </ref>
== USE aspects ==
=== Society ===
Much influence from the prototype will be noticed by society. Deforestation is an international problem with huge and devastating consequences which includes but not limits to soil erosion, water cycle disruption and greenhouse gas emissions (Cook, 2018)<ref> Cook, M. (2018, April 19). Four consequences of Deforestation. retrieved from Sciencing: https://sciencing.com/four-consequences-deforestation-7622.html</ref>. This results in a loss of biodiversity and will also influence human lives. Greenhouse gas emissions for example contributes to global climate changes. Deforestation thus has great influences on the society in ways that cannot be imagined. When no actions are taken against deforestation, the problems arising are getting bigger and bigger with the years. The society is currently looking for solutions to these problems. The prototype is created to combat deforestation and therefore the consequences of deforestation. If deforestation is reduced, the society will benefit from this since the prototype makes reforestation much easier and cheaper. It is more efficient than current ways of reforestation and is therefore a better solution to decrease the consequences of deforestation.
=== Users ===
Apart from the society, which will mostly be influenced by our prototype. Users is another group to consider. Users can be divided into three groups: primarily users, secondary users and tertiarily users.  Primary users are those persons who actually use the artifact; secondary users are those who will occasionally use the artifact or those who use it through an intermediary; and tertiary users are persons who will be affected by the use of the artifact or make decisions about its purchase (Abras, Maloney-Krichmar, & Preece, 2004)<ref> Abras, C., Maloney-Krichmar, D., & Preece, J. (2004). User-Centered Design. Encyclopedia of Human-Computer Interaction, 1-10. </ref>. The primary users of our prototype will be foresters. Foresters are going to use the prototype to combat deforestation and the prototype helps them to plant more seeds in less time compared to planting them with no help of smart technology. Next to the foresters other users will be influenced by the technology as well. Secondary users are companies that are involved in the maintenance and production of the prototype and the government, more details on this can be read in the enterprise and government section. Tertiary users of the prototype are in principle all living residents of the world. The consequences of deforestation will eventually influence everybody and the prototype will decrease these consequences and thus each living individual will benefit from the prototype.

Project Statement

Wildfires are occurring throughout the world at an increasing rate. Great droughts in various regions across the globe are increasing the probability of wildfires to occur. National parks deal with major wildfires multiple times a year. Areas devastated by wildfires are mostly devoid of life, while potentially still having an extremely fertile soil containing all the biomass left after the fire. Artificial reforestation can accelerate the natural process which accounts for the regrowth of the forests. This process might be enhanced by means of technology, for example by deploying robots that plant seeds of saplings in these areas.

This project investigates the possibility and potential of utilizing robots to restore these devastated areas to their former glory. In order to investigate this possibility, a thorough analysis of different methods of reforestation is made first. By comparing methods of reforestation a great deal can be learned about which negative aspects of the current reforestation methods should be enhanced by a new reforestation robot. Also, this analysis will explore if a new method of reforestation is needed at all. Beyond this, two case studies are investigated. These case studies show how reforestation and forest fires are currently being handled. The case help studies help to get a better understanding of what the robot should be able to do and what it ought not to be able to do and thus help to define design criteria.

Finally, multiple preliminary designs are made for the seeding mechanism of the robot which would accomplish all necessities found during the analysis of the different reforestation methods and which follows all the criteria discovered in the case studies. Out of these designs, the one ranking highest on the criteria unraveled during the literature review and case studies is chosen to be the best suitable seeding mechanism for the future robot. Additionally, a design is made for a user interface that will allow the staff of a national park to control a swarm of robots in a user-friendly and non time consuming way. Lastly, some suggestions for future research are given, in the topics of what other crucial functionalities the robot requires, how the robots would be able to communicate among themselves during operation, and how the robots would be able to communicate with the user in case of unforeseen circumstances. To conclude, this project aims to assess the necessity of a robot to rebuild a forest in a national park after a forest fire, discover the functionalities such a robot must have and design a user interface to control such robots based on the gained information.

Approach

The problem will be approached by means of a design question. What would be the best design for an effective seeding mechanism which can be used in a mobile robot deployed in a reforestation operation, and how would this robot be controlled? The gross of the project is carried out sequentially as each subject builds further upon the conclusion reached during the last subject, which is represented in the structure of this Wiki consisting of several subpages corresponding to these subjects. Albeit that the project is carried out sequentially, within each sequence several tasks are divided such that they can be carried out in parallel by different group members. During the last phase of the project, when the major milestones have been finished, the project wrap up consists of several small independent task which will allow us to abandon the sequential structure which was necessary during the other phases and carry out these tasks in parallel to gain in time.
