Arm Day

It is with deep sadness and a heavy heart that we announce the tragic passing of Bicep Number 2. At 11:27 AM today, we lost a cherished and irreplaceable member of our community. Bicep Number 2 brought strength, support, and resilience to those who relied on its unwavering presence.

As we grapple with the profound grief of this unexpected loss, we reflect on the countless moments where Bicep Number 2 provided strength and stability. Its absence leaves a void that cannot be filled, and the weight of this sorrow is felt by all who knew and relied on it.

During this difficult time, we extend our deepest sympathies to those directly affected by the departure of Bicep Number 2. May you find solace in the memories of the strength it once provided and the impact it had on our lives.

In memory of Bicep Number 2, we invite you to join us in a moment of reflection and remembrance. Let us honor its legacy by cherishing the strength it symbolized and the support it offered to us all.

Rest in peace, Bicep Number 2. Your presence will be profoundly missed, and your memory will forever live on in our hearts

We just had today the idea of how we will make the forearm moves basically it is just for now the idea but he have put the video of how 

Here you can see our lastest version of the elbow :

(no fingers were burnt in the making of this piece) (some plastic inhalation did happen) (the engineer we used had a sore throat)

The syringe driver has gone through multiple iterations, going from hand use, to a failed attempt using online 3D models :

, to finally our lastest and best iteration yet : 

Today was a big day for us. we've made the first arm elbow or something like that prototype. It is a one degree freedom lever. With my strengh we've made the arm lift a 2.5 Kg weight. It may take more but we need to check with the motor how much it can lift. The syringe driver will soon be ready so we hope everything will come to place.

The the code 1.3 was finished today.

https://github.com/Eratosteme/ArmCode/tree/main/Projects/ArmCode_1.3

-this code enable the use of the syringe driver

      * get user input from the buttons

      * graphical interface with the screen

      * control the motor

Fixed the issues that plagued the power supply of the motor      

        * we made our own USB to Jumper wire adapter

        * connected the ground of the esp32 and motor so that they communicate well despite having different power supply

today we did a lot ;)

- tested several programs and telecommunication library for their compatibility with our esp32 t-display

- tested the upper limit of the resistance of our system from water pressure

Last tuesday we have made a connection between 4 muscle prototype. Now on this probably be consider as fiber muscle. The video of it can be seen in the files. 

Today we did the fifth muscle prototype. It is basically the same as the fourth one exept that the net used is bigger than the previous one. It will allow the ballon to inflate more and by that to retract more. 

We've made the fourth muscle prototype which now contain a way to fix the end of the muscle. It works like the last with water.
