A robotic flower that needs water and sun to operate. The design was made by students of the robotics club of the Experimental Elementary School of Florina, during the 2015-2016 season.
The robot is made by Lego NXT parts and it is fixed on a construction with a small water tank (plastic container) that has a simple water runoff system using straws. The behaviour is as follows:
-
While the tank is empty the flower has it’s petals closed and does nothing.
-
When water is added into the tank and passes a certain level the floater (touch sensor) gives order to the flower to open it’s petals.
-
The water in the tank slowly runs off through the straw.
-
While water is over the certain level for the floater to work the flower has it’s petals open and searches for light (light sensor).
-
If there is low light it rotates left and right until it finds adequate light.
The flower has two motors (one for openning and closing the petals and one for rotating), a light sensor, a touch sensor (floater) and a distance sensor (for changing the rotation direction).
The robotic flower was presented by students in European Maker Week 2016.
