Project

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.
