Wind turbine experiment

by Filippos and Vaggelis Atlasis 

We conducted an experiment to find out which wind turbine design generates the most energy. We used the EV3 energy pack to build the turbine and a fan to create "wind". Attached below you will find our full report created as a pdf as well as some pictures and videos of our experiment. The report contains everything from an introduction and method, to our analysis and a conclusion.

Using a Robot to Estimate the Azimuth Angle of the Sun

by Vaggelis and Filippos Atlasis

Using a self-constructed Ev3 Mindstorm robot, we managed to measure the Azimuth angle of the Sun at different times during the day. By clicking on this link (you can also find it below as an embedded pdf file), you will find attached a complete report on our investigation, including details on the construction and programming aspects of the project, our methodology, the analysis of our results as well as a reference to the mathematical model used to find the exact value of the Azimuth angle at any given time and day. 

The Mindstorm robot aligned with a compass, facing North
