Problem

To keep residential areas clean and neat, lots of tools are used. Most of the tools are operated by humans, but some new tools can do some tasks autonomous. Can't this be done by one autonomous robot? We think the most common tasks can be performed by an autonomous robot.

To keep city centers clean and neat, there are people that collect trash. They are just picking up the trash, they see. Trash is in many cases underneath the benches, because it is the most common place to eat for people. If there are people on the bench, then the people that are collecting the trash have to do a big job to get to the trash underneath the benches and in some cases the people sitting on the bench have to stand up or lift their legs to enable the trash collector to pick up the trash. A robot can be compacter. It can be in most cases come under the bench without bothering people.

People, money and time is being spend on maintaining sidewalks, while there are a lot of other sectors, such as assisting elderly, where there are not enough workers. Is there a cost-effective way to free up resources from maintaince, to allocate to more important, resource-deprived sectors?

When farmers grow crops, the have to deal with weeds growing on their fields in between their crops. To remove these weeds, pesticides are used. These pesticides can be harmful to insects, animals and humans and might even contaminate (ground)water. Clearly an alternative is needed.

Problem statement

In the current situation, a lot of pesticides are used in farming. These pesticides are used for treating bugs and diseases, but also for weeds. With the trend to be more environmentally friendly, we are looking for alternatives for pesticides and big farm trucks. A possible solution for this problem is a cooperation of small autonomous farming machines, which can control a field together. However, this solution is not new, people have already been working on the navigation of these small machines and on the detection of weeds in fields of crops. [1] That’s why we will try to make a weed picking device to be able to pick weeds without damaging the crops. For these small devices, we see future in the vertical agriculture as well, because they allow for a higher field density.

Objectives

• The system must have the ability to do tasks, like lawn mowing and trash picking
• The system must be able to go autonomous to the place, where the task has to be performed
• The system has to give a warning to the owner in case of technical disorder
• The system has to ask for help of human if needed

• The system must have the ability to collect trash
• The system should have the ability to reach narrow places
• The system could have the ability to drop the trash on some location without the help of human
• The system could have the ability to attend the owner on many trash (full trash can)

RPCs

Requirements

• The system recharges autonomously
• The system must be able to differentiate crops from weeds
• The system removes weed from the farm field and collects it for disposal
• The system moves itself around the farmfield, following a predefined pattern unique for each farmfield

Preferences

• The system can operate for a long time before having to recharge
• The system should make minimal errors in recognizing weeds
• The system can work with 3D patterns, allowing applications in 'farm flats', reducing land area use

Constraints

• The system has to be more cost-efficient than human workers
• The system has to be intelligent, has to know what to do
• The system does never run out of power, has to return to the recharging station in time
• The system does not use pesticides

Users and other stakeholders

• Farmers
• Consumers
• Governments
• Society

Project setup

Approach

After reviewing the literature, we will determine the requirements for the system. Based on these requirements we will investigate implementations for these requirements and analyse their suitability. We will analyse the costs associated with a solution and compare this to the current costs of using pesticides, the effects on the stakeholders and on the future of farming. Finally we will conclude with a recommendation for or against the automated removal of weeds on farm fields without the use of pesticides and recommend future research topics.

Planning

For each week, there are points what we plan to do in that week. Planning can change over the weeks, dependent on the progress in the project. Final versions of the documents will be delivered at the end of the quartile, but concept versions will be delivered earlier.

Week 1

• Introduction to course
• Brainstorming about problem
• Make problem statement
• First idea on plan for project
• Literature study on problem

Week 2

• Updated problem description
• Concrete planning for project
• Make plan more clear with introduction
• Analysis of literature found in week 1
• First idea on requirements
• Start on USE stakeholder analysis

Week 3

• Concrete decisions on prototype
• USE stakeholder analysis
• Make requirements ready to start on design

Week 4-6

• Work on prototype
• Analysis of requirements based on prototype and update if needed
• Analysis of decisions made for prototype and update if needed
• Update other documents if needed

Week 7

• Finalize prototype
• Prepare presentation

Week 8

• Presentation
