Opening Flower Device

assembly of the differents parts

reaslisation of the circuit

The circuit it's from somedy else: https://racheldebarros.com/arduino-projects/control-nema17-with-a4988-arduino-wiring-and-code-guide/

Today, we had issues with the material, we found another metal stick without the black part at the bottom, and we found another stepper motor, bigger and faster to make it turn faster and so the petals will be able to open and close also faster. 

The inspiration for the structure

Today we re did the drawing to make it more realizable and started searching for materials.  So, our idea is to create a moving flower. We want to put ideally 5 petals that can open and close thanks to a system. >span class="NormalTextRun ContextualSpellingAndGrammarErrorV2Themed SCXW9021383 BCX0">turn the stick, then it will create a translation that will allow the petals to open and close.

Today we finished the second prototype with motors.  

And then, we tried to decide how to improve it, by changing one movement to another. We are inspired by the worm drive mechanical. So, we are thinking about turning rotation into translation to make the petals open and close.  

This is the sketch of the second prototype

• Prototype our ideas  

• Objective is to modelize a movement and make it designable  

Ideas : 

• We started searching for inspiration on the web, making fashion moves (dresses...).   

• Flower brooch on which the petals open and close 

• First prototype: make a flower with cardboard and make it move with wires and our hand.
