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.
