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.

Problem statement

How can tasks of maintaining residential areas be combined into one (modular) robot?

How can robots help in keeping city centers free from trash?

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 collects trash (litter, leafs, snow, ice) from the streets
• The system has to be modular, e.g. be able to do different tasks
• The system recharges autonomously

Preferences

• The system can reach narrow places
• The system can navigate around most obstacles
• The system can operate for a long time before having to recharge

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

Users and other stakeholders

• Municipalities: responsible to maintain the residential area
• Citizens: clean and safe neighborhood
• People that are maintaining the neighborhood: can focus on other tasks, that currently would not be done
• Society as a whole
• Enterprises that specialize in maintenance of public grounds

• City cleaning service (user): easier cleaning of the city center and better for human, because they have to stoop less to pick up trash under obstacles, like benches
• Shop owners: cleaner and more attractive city center. More customers leads to more sales.
• Shoppers: cleaner and less inconvenience of people that are trying to get the ground under your bench clean.

Project setup

Approach

After reviewing the literature, we will determine the requirements for the robot. Based on these requirements we will design a robot to maintain the sidewalks, which will include a detailed physical design and a design of the software running the robot. We will analyse the effects of the use of the robot on the stakeholders and determine the costs of building, deploying and maintaining the robot. The design process will be iterative and each cycle ends with a prototype, which we will analyse and improve if needed.

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 prototype
• Start on prototype

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
