Appendix

The Group Contract

As a group, EGM had one target, to bring life to ICKI. This would not happen but with cooperation and hard work. By signing this contract you declare:

* EGM will do the tasks they are responsible for by the internal deadline decided.

* If EGM had any problems fulfilling any of their responsibilities they should inform the group leader in advance.

* EGM should back up all their group mates in unexpected and hard situations.

* EGM should trust their group mates for their capability of doing their own responsibilities however this does not mean that they cannot say their opinion and ideas.

* As the work break down has been decided when the entire group have been together, EGM is not allowed to complain about the inconsistency in the work division among the members of the group.

* In any case when all the group members cannot get to agree on one subject they will have to count votes. If they tie they will have to ask a person’s opinion every group member trusts. (Or they can flip a coin alternatively.)

* If EGM wants to change any of the plans, they should discuss it with the rest of the group first. They are not allowed to accept doing something and do it in their own way without a group agreement.

* EGM is responsible for attending all the group meetings unless they have a convincing reason not doing so.

If any of the group members disobeys any of the statements above, the rest of the group has the right to reduce their mark upon agreement.

Introduction

The purpose of this initial report is to survey the created plan made in order to accomplish the given Robot Project. This project is given to entire second year and the purpose of the project is to design and construct an autonomous robot that should follow the dark line track on a light background. First there is an overview on the line follower robots in literature review , The aims, objectives and requirements will follow the review. Literature Review

The line-following robots are classified under the “Mobile Robots”. Mobile Robots are the robots which do not have a fixed base; they can move around and do not physically stand at one location. These kinds of robots are fairly important as it is stated in this part of the article from Wikipedia’s Mobile robot is stated below: “Mobile robots are the focus of a great deal of current research and almost every major university has one or more labs that focus on mobile robot research. Mobile robots are...
