Subject

Globally there are about 285 visually impaired people, of which 39 million are totally blind. There is a shortage of guiding dogs to support the visually impaired persons. For instance in Korea alone, there are about 65 guiding dogs in total and about 45.000 visually impaired. Next to the shortage of guiding dogs, there are also other drawbacks. The training of guiding dogs for instance is difficult, while only 70% of the trained dogs will eventually be qualified to guide. Therefore, there is a need of innovative ways in supporting the visually impaired. We propose a guiding robot to help solve this problem.


Objectives

Autonomous

We want to accomplish that the robot can navigate itself through an environment, possibly filled with either moving or solid obstacles. This process should be fully autonomously, hence without the input of any user during the navigation process. This goal is important since visually impaired people will not be able to guide the robot through its navigation process. If this was necessary, the complete purpose of the robot is abandoned. Therefore, the only actor involved in this process is the robot itself. The robot must be able to navigate itself and the user on paved area. This type of area is also the kind of terrain an average person walks over the most. The scanning setup will consist of one or more camera's. The robot will not have advanced radar equipment. Also, the robot will not be able to travel on paths with a high height differences, like stairways. The robot must be able to guide exactly one person autonomously through an environment, matching our environmental constraints. This task will be accomplished when a person gets from point A to B safely, e.g. without hitting obstacles on its path. This goal can be accomplished by implementing obstacle recognition software for the attached camera's. Together with an avoidance algorithm, the robot will be able to navigate around obstacles on its path. By using constraints such as no advanced radar equipment and a restricted area type, this goal is realizable.

Users

The robot we want to develop and are describing in this wiki is a robot to replace the guiding dogs. This robot will be used by the visually impaired the way they are now using guiding dogs. This means that they will use the guiding robot to walk inside, outside and to find there way to a store, bus stop etc. So the robot will not only have an impact on the visually impaired that is directly using the guiding robot it will also have an impact on the people in the direct surroundings of the visually impaired. For example when a visually impaired using the guiding robot wants to cross the street the drivers of the cars must really on the guiding robot to not cross the street if this isn’t possible. So this gives us the visually impaired who are the primary users, the people in the surrounding of a visually impaired that is guided by the guiding robot as the secondary users. And then we have the developers who are the tertiary users.

Users

The users and there different needs of the guiding robot

Visually impaired (primary users)

  • Making it save to walk outside
  • Making it easier to make a walk outside
  • Navigate them to different destinations

the surrounding (secondary users)

  • That the guiding robots detects cars, bicycles and pedestrians
  • The guiding robot walks around obstacles
  • The guiding robot walks where it's aloud to walks and is save to walk

developers(tertiary users)

  • The guiding robot is better and more reliable then guiding dogs
  • That it's easy to adapt the software
  • That the guiding robot has as little maintenance as possible

Approach

  • Research
  • Which robot we will use to implement the software.
  • Perceiving of the environment and recognizing obstacles.
  • Obstacle avoidance.
  • Adapting to the environment (tension on the rope).
  • GPS navigation.
  • Voice recognition.

Milestones

During this project, the following milestones have been determined. They may be expanded once we have a better understanding of how we are going to tackle the project. Especially the decision on whether to use an existing robot or creating a robot will heavily influence these milestones and their deadlines. Note also that the planning also lacks details, which will be filled in in week 2.

Milestone Deadline
Research is complete Week 1
Hardware is available (either full robot or necessary parts) Week 3
Robot can scan the environment Week 5
Robot can keep the user in mind Week 6
Robot is fully autonomous Week 6
Robot can guide the user in a restricted area Week 8
