 **Correction:** There was a problem with the vertical movement, because the motor was rocking. The problem was the coupling, which had two holes, for the motor and the threaded rod, not well aligned. After making this component again, the movement was performed without any problem.\\ **Correction:** There was a problem with the vertical movement, because the motor was rocking.

 +=== 7.11.5 Sun Tracking test ===
 +After the corrections of vertical and horizontal movements the sun tracking mechanism was tested.\\
 +** Method:** The mirror was placed near the window and the focus point was adjusted. Then the mirrors behaviour was observed for over 1 hour.\\
 +**Expected behaviour:** The mirror should reposition itself every 1 minute and the sun spot should not move.\\
 +** Result:** The mirror was repositioning correctly. the sun spot was not moving. Below is the timelaps video of the whole test and the photos which were taken every 5 min for 1 hour.\\

 +**Conclusion:** The repositioning mechanism works properly. The mirror is able to track the sun on its own.

 The goal of this project was to develop a Self-Oriented Solar Mirror (SOSM). The mirror must track the movement of the Sun and reflect the sunlight onto a predefined area. The creation of the Sun tracking system was one of the main challenges for the team. The SOSM had to detect the Sun by itself with the aid of software that knows the path of the Sun.  The goal of this project was to develop a Self-Oriented Solar Mirror (SOSM).

 The Team is proud of what they accomplished, but if the Team had to do it again, the Team would do some things differently. First of all in the beginning there was a lot of indecision about the purpose of the mirror. If the Team had solved this earlier on, the Team would have had more time for the project development. Furthermore the purpose didn’t really need to be decided because the automatic orientation had to be the Team’s main focus. The Team is proud of what they accomplished, but if the Team had to do it again, the Team would do some things differently.

 At the end the Team lacked a little bit of time, the prototype was not finished before the report had to be handed in and so the Team couldn’t do a 24 hour test. For the tests and results it would have been better to place the mirror with the software and see if it starts when the sun rises and moves during the day the way it suppose to and stops when the sun goes down. At the end the Team lacked a little bit of time, the prototype was not finished before the report had to be handed in and so the Team couldn’t do a 24 hour test.

 The Team also mentioned some risks in the beginning of the report; the Team came in touch with a lot of them. During the building of the prototype, some materials arrived late, some holes were made too big/small, and the Team probably went a little over budget although the price of the 3D-printed parts is unknown. The Team also mentioned some risks in the beginning of the report; the Team came in touch with a lot of them.

 On the other hand, the Team can certainly say that they achieved many things. Although the team members didn’t know each other, the team members managed the work of 5 people. Every team member did their part and if there was a disagreement, the Team managed to solve them quickly. In the beginning of the project the Team made some rules, one of them was that every decision needs a majority of four to pass, and everyone kept that promise.  On the other hand, the Team can certainly say that they achieved many things.

 The Team lowered their environmental impact by choosing renewable resources but also by choosing to send the product unassembled. By sending the product unassembled, less transport will be needed, but also less packaging. The product can also be made solar powered; this was unfortunately not within the budget. The Team lowered their environmental impact by choosing renewable resources but also by choosing to send the product unassembled.

 The Team designed a prototype and a control system; the Team built a moving structure, assembled the electrical components, developed the software and eventually finished the prototype. Although the mirror doesn’t move as smoothly as the Team had wanted to, the mirror moves the right way and thus works the way it should. The Team designed a prototype and a control system; the Team built a moving structure, assembled the electrical components, developed the software and eventually finished the prototype.

 **Margot Gutscoven: ** // EPS thought me to work in group with people I barely knew. You should stay positive and give them the benefit of the doubt. Also that in a project you have to think of more then just the obvious technical aspect, you have to think of marketing, project management, the ethics, etc. It also brought me out of my comfort zone of construction and showed me a little bit of programming, which in a way I find unfortunate, because I didn't always feel helpful. Nevertheless, I am glad I joined this program, I definitely made new friends, great memories and learned new things. // **Margot Gutscoven: ** // EPS thought me to work in group with people I barely knew.

-**Raymond Quinn:**+**Raymond Quinn:** //I found the EPS a greatly rewarding experience. The opportunity to enhance my team work, communication and interpersonal skills in an international environment will prove invaluable. EPS also forced me to think about the less technical aspects of engineering project work – Ethics, Sustainability and Marketing – issues that I don’t often thoroughly consider during project work. It was also rewarding to take on board the ideas of others, as often decisions I disagreed about or was unsure about turned out to be good ideas after a group discussion. My only disappointment during an enjoyable semester was that I found it difficult to apply my knowledge of power engineering to the project but this allowed me to take on other unfamiliar roles and also to learn more about electronics and computer science.//
