Our sunflower is a tiny robot flower which has no mobility. It can only and continuously turns its face towards the sun like the sunflowers do.
Step 1: Parts
The robot sunflower is made from plastic parts taken from old CD drivers and junk home equipment; a small dc motor and reduction gear from the CD-R sawed together with some plastic parts, a tiny solar panel, some other plastic parts taken from an old aquarium filter and a simple, 4 transistor circuit made by me.
Our flowers uses the energy that comes from the sun to find more sunlight. So it continuously turns its face (the solar panel) towards the sun. As the same way sunflowers do. You can put it at balcony or window ledge. I've glued a magnetiesed CD holder disk taken from the old CD-ROM driver to the base of the robot. So when it is put on to a mettallic surface, it holds the surface firmly by the use of magnetic force.
