Problem statement and objectives

Aid workers can not always estimate the critical situation of a disaster area well enough, because they do not have enough information to act upon. Victims can be helped quicker if aid workers would be able to operate in small spaces with the right equipment.

Objectives:
The following objects are SMART objectives.

• The solution should localize the victims of a disaster area
• The solution should be ready for use
• The solution should be tiny/small
• The solution should be adaptable
• The solution should be strong (enough for mechanical loads)
• The solution should be autonomous
• The solution should be user-friendly
• The solution should be able to function in an unknown and dynamic environment
• The solution should be durable

Users & User needs

Primary users

Needs

• Quicker discharge of patients

Approach, milestones and deliverables

Approach

To tackle this project, we started with extensive research on the state of the art. This is done by examining the current literature on the subject. These examined papers outline the current state of the problem, solutions to these problems, and their flaws.

After obtaining a better view on the problem at hand, the USE (user, society and enterprise) aspects are analyzed, to determine why this problem is relevant. These three aspects should always be kept in mind during each stage of the project. These aspects may sometimes ask for different solutions to the same problem, so they must be analyzed to determine which aspect should be taken into account more, and compromises must be made. Also different subproblems may ask for different USE aspects, but two solutions from two subproblems may not always be able to be combined, meaning that choices must be made.

After having analyzed the USE aspects, a scenario will be made where the robot shows of its capabilities, and multiple persona’s will also be made who come into contact with the robot. Research has also been done about the interaction between rescue robots and the human victims. These papers will be used and important factors for the product to have will be determined.

Then, we will start the production of our own spider robot. As with each project with a tangible deliverable, the robot starts off as a sketch. Multiple designs will be made, and the best one will be chosen. This will most likely be done by making simplified prototypes. Another option is creating only parts of the robot like the legs. After this is done the necessary components will be analyzed and subsequently tested. After we know that the different components work, they will be assembled into our final product. After obtaining a finished product it will be tested and evaluated. If improvement is needed, the product will be improved. This does mean that planning of the different tasks is crucial. The sub-components should be finished on time so they can be tested and assembled into one product. Therefore the different parts will be created as early as possible. This can clearly be seen in the planning.

During the whole process, a report will be written in which the process is outlined in a more detailed manner, and which also follows our progress. This report will also more finely describe the problem and the solutions. Because this is done alongside the creation of the actual prototype, planning is important again. Some people will be working on the product and some on the report. This also means clear communication is of utmost importance. Alongside each progress meeting, the group will come together once or twice a week to discuss what has already been done and what should still be worked on. This way it will become clear if the goals will be reached in time and the project is on track.

After all this is done a presentation will be prepared and presented, the wiki will be done, and all deliverables will be handed in.
