Hello everyone!
Our names are Sorana, Alesia and Cezara and we’re from “Emil Racovita” National College in Cluj-Napoca, Romania🇷🇴 . We are 16 years old and students in the tenth grade.

We love manual work, creativity and ingenuity from everyone around us. This facts made us choose, of couse, this beautiful topic😄

Can’t wait to hear your ideas💡,to get to know you all and to work together!🥰

It's very nice to meet you.😁 Our names are Lucille, Méline and Orlane. We are 15 years old and also in tenth grade (seconde in France). We study in "Lycée Val de Durance" in Pertuis.
Here are some of our interests:
🌺Lucille: I am a girlscout, I play harp and like reading fantasy books
🌼Méline: I like ballet dancing and I talk a LOT
🌸Orlane: I do synchronized swimming, I like holidays and reading
At first we were doing the 4th topic but we moved to this one. We hope to have some fun🥳

Hi my name is Lea and I live in France. I study in the lycee val de durance and I am 16 years old. I really like reading and making things with my own hands. I listen a lot of music of all genres like rock, pop, electro etc.

PS: Our topic is the second one but we are the only one to do it so we comunicate with you but we work on the topic 2 :)

Hypothesis:
1) Test without braids to try a prototype. (picture 1)
2) Create a tiny bag (size: smartphone)
3) Mathematical approach: calculate the number of square meters of sheets used

# data[].attributes.body
Since our teacher told us to, we tried to make a braid-like drawing on the computer by using excel. That was really hard! It took me the hour to finally figure it out but I'm not sure what we can do with it. Next time we'll continue the bag project I think
Méline, Lucille and Orlane 🤍

We are Tim and Clément and we live in France. We are 15 years old and we study in the Bellevue high school. We are fond of Lego and we love science. Let's go work and good luck.

# data[].attributes.body
We were thinking of using robotics as well. We have the idea of ​​making this mechanism also using light bulbs, wires, cables and current, so that the correct braid will be shown with a green light bulb, and if it is wrong, a red light bulb.
This concept seems very difficult to achieve, but we will try our best.

Our names are Vlad, Ștefania, Alexia and Ilinca. We study at ‘Emil Racovita’ National College in Cluj-Napoca, Romania. We are 16 years old and we are 10th graders.

Vlad: I like practicing sports. I have fenced for 6 years and I have won several competitions. I am also passionate about reading and music. I played piano 2 years. I also enjoy mathematics and informatics.

Ștefania: I like to swim, dance and paint, which I started 11 years ago. I like physics and maths. I have participated in several scholar competitions at these subjects.

Alexia: I love music, I enjoy singing and I’ve been playing guitar for 3 years now. I am also passionate about maths and I plan to have a career in this subject.

Ilinca: I like skiing and dogs. I am passionate about biology and I wish to become a surgeon because I want to help people.

Our idea is to make a weaving which consists of 20 paper strips: 10 vertical ones and 10 horizontal ones. Because we wanted to build a weaving robot, we started by weaving the strips ourselves to find a pattern.
Alexia, Ștefania, Ilinca, Vlad

# data[].attributes.body
Soon we realized that if we number the vertical strips from 1 to 10 and we place 2 sticks at the bottom of them: one attached to the odd strips and one attached to the even strips, we can use the first stick to raise or lower the odd strips and the second to move the even strips forward and backward like in the pictures. To make this possible we also needed to cut the odd ones shorter so that the even ones can be moved backwards while the odd ones are lowered.

Alexia, Ștefania, Ilinca, Vlad

# data[].attributes.body
Each time the odd strips are raised and the even ones are placed forward (down) we can introduce a horizontal strip between the 2 sets of strips. Each time the odd ones are lowered and the even ones are placed backwards (up) another horizontal strip can be introduced.
Alexia, Ștefania, Ilinca, Vlad

# data[].attributes.body
After we figured out how the weaving works we thought that we could use the wheels from an old robot to build a mechanism which moves the even strips forward or backward and raises or lowers the odd ones. We started by disassembling the robot as we only needed the wheels and the main circuit board. We thought about how we can make the robot move the 2 sets of vertical strings simultaneously (move the even ones forward while lifting the odd ones or move the even ones backward while lowering the odd ones), so we connected the sticks with a string and used the wheels as pulleys. The whole mechanism is placed on a cardboard box because the string has to go under the strips as well, so we made 2 holes in the box and pulled the string through them. The strips are placed between the wheels, which are sitting on holders made of cardboard.

This is just a prototype, so everything (besides the wheels and the main circuit board, of course) is made of cardboard, but we still need to figure out how to incorporate the horizontal strips automatically, as we’re still doing it manually at the moment.

This is our code so far but we are thinking of incorporating an ultrasonic sensor to detect movements in order to make the wheels (pulleys) stop on their own.

Hi! Because we are going to do our presentation together at Nice, I started to make a support (see attached picture: it's in the same style as our poster) and when we will be together at the VDD high school; we put all our information/research together on the slides. (tell us if you like it or not!)
