• It's not over

    The project updates are as follows : 

    The theoretical part:

    We wrote detailed documentation on Hackaday

    We made a clear list of requirements (goals, components, steps, constraints)

    We understood and organized the Arduino code

    We started 3D modeling in Fusion 360, working on the three articulated arms

    At one point, we had a tiny bit of hope that we could finish the whole thing on time – we got hyped, thinking it might even be the best project in the class.
    But since we wanted to do everything ourselves, we discovered that almost every part we designed had some kind of issue: too thin, not fitting the servos, unstable, or just not printable.
    3D modeling, which we thought would be pretty straightforward, turned out to be way more complicated – especially when trying to assemble moving mechanical parts.

    So we looked for alternatives, checked out 3D models online, and watched a bunch of tutorials.
    And then… we realized most realistic models had over a hundred parts – with gears, axis systems, wedges, ball joint supports…
    Way too complex for our already packed schedule.

    So we made a strategic decision: only keep the main parts needed to simulate the basic functions (mobile base, articulated arm, rotating cabin), and leave out the so-called “secondary” parts.
    This helped us focus on the essentials, but it also had a downside: the project won’t be finished in time for the original deadline.

    Still, we learned a ton, and the adventure isn’t over. The project is still going, and we’re planning to finish it soon – after exams, when we finally have time again.

    Moral of the story:
    Building an articulated excavator isn’t just a small DIY thing… but it’s super exciting.

    Alright. We won’t lie to you: we caught a case of time kleptomania. 
    Yes, that weird condition that stole two whole weeks from us before we even realized we only had two left to build a full excavator. 😅
    But giving up was not an option (even if, honestly, we kinda wished our arms were already 3D printed).
    We rolled up our sleeves and got serious about the heart of the project.

    The project really picked up speed in the last two weeks, with strong involvement from the whole team.
    Even with last-minute constraints and exams coming up, we held several meetings on Discord, shared our progress in video calls, and worked in parallel on both the 3D modeling and the code.
    We set up a good coordination system, which should allow us to finish the project quickly once exams are over. 

    However, we leave you with the 3d modelling of the excavator and keep you informed of the progress of the project.

    during the session we make the code of the 4 motors. We have 4 different codes: 3 for excavator's arms and 1 for wheels. We also have detailed the technical composant and their needs. We choose to modelize the wheel and its caterpillar on Fusion. The cabine will be on cardboard and we still don't know for the arms.

    Today We are supposed to make the cardmodel of the Tiny-Excavator, it's an important part because thank to this part we can see if our sketches measures are realistics and in adequacy with our hopes for the project and more generally we can see the failure of our projects hopes and our sketch. Today we started the cabin's carboard

    We get the idea to make an excavator.

    We realised the achievable goals and advanced goals that we want to reach. We wrote step by step  specifications of our project. 

    We have make a first sketch that modelize the pieces movment and an other sketch with more details about each pieces of the excacator and the dimesnions. 

    For the next session we will make the cardboard model and modify the sketch if we need.

    Here are the pictures:
