Rotation system

At first we were having problems actually finding a way to make the solar panel rotate because we tried to put the panel on 4 retractable poles. We figured that we make one or more poles longer or shorter than the others which would in turn rotate the panel from side to side. But unfortunatly that didn't work for multiple reasons first of all we couldn't fine any retractable poles and secondly we didn't have a way to move them even if we had them (unfortunatly we don't have any photo sof that idea). So after scraping that idea we figured why not go back to basics and just use good old Lego and we do have photos of that so here they are

What we actualy did was incredibly simple we just took a Lego brick which could pivot from side to side. As shown below:

And then we then put a brick that can  pivot upwards and downwards. As shown below:

And then we put a Lego slab on top with little grooves in them so that we could simply slot the pannel in.

To see the final effect just look at the photos above.
