Project

Project Statement

Wildfires are occurring throughout the world at an increasing rate. Great droughts in various regions across the globe are increasing the possibility of wildfires. National parks deal with major wildfires multiple times over a year. Areas devastated by wildfires are mostly devoid of life, while potentially still having an extremely fertile soil with 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 on different methods of deforestation is made first. By comparing methods of reforestation a lot can be learnt about what aspects the reforestation-robot should be an improvement on compared to older reforestation methods. 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, a design is made 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. Multiple preliminary designs regarding different seeding mechanism were made, one of which was chosen based on the criteria emerging from the literature review and case studies, and is resolved in further detail. Lastly some suggestions for future research are given, mainly in the topic of what possibilities exist for the other crucial functionalities of the robot, and how they would merge into one final product capable of doing what should be done. 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 make a potential design based on the gained information.

Approach

The problem will be approach by means of a design. What would be the best design for an effective seeding mechanism which can be used in a mobile robot deployed in a reforestation operation? 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 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.
