Hello, i don't have the knowledge with mindstorms or this model, but i think the other experts on this forum might have an easier time helping you with more information: What debugging steps did you take: - checked the mechanics, does everything work as expected? - checked correct function of each sensor input, e.g. do you get the expected sensor value in the program when a blue square is in front of the sensor? - where in the code does the error occur, e.g. what condition isn't being fullfilled for the loop to be exited? A video of the problem and the movements up to this point might be useful as well. That seems like a good and fun project, i wish you good luck and much fun getting it to work

I feel like the motorised coupler would be awesome on a rc model. Imagine trying to attach the shovel remotely, changing between them, ...

That's great! Only the frowning mouth doesn't fit how fun this is Do you have pictures of the inside? I don't know those system pieces but it feels like there is not a lot of space for all the motors, especially including the battery box. It seems to be a really compact construction.

No, i get what you mean. Maybe another way to put it: "A clutch that engages even when you're doing everything right." An example that kind of fits: 42043 Arocs has one that allows the pneumatic pump to keep on working when the supports reach their end position.

No wonder, moving so much weight with reliable mechanics is quite an impressive feat.

Completely agree with @howitzer there: sharing the building process and talking about it with the members is part of the fun. I also have several threads of unfinished TC entries.

Wow, i love that! Gives me great "Homeworld: Deserts of Kharak" vibes. Technic as spaceship works surprisingly well. The backstory was a nice touch.

That's incredible! I love the idea of such a machine built in Lego. Looking forward to following your process.

Why don't you use a 24/12 gearing? This is achievable with a 1 stud vertical offset.

Thank you for those videos, they are great inspiration! Incredible that they manage to position those balls that precisely!

I think that's a good idea, to make this two separate contests (maybe with at least one vehicle in between to prevent burnout).

YES! i'm not sure i will be able to participate, but i love the idea. These kind of models really are underrepresented in the LEGO lineup and i feel in the MOCs as well.

These three are all the same ecosystem, just different controllers (as far as i know) pybricks supports them all.

That's a nice bike I love the detailed engine with timing belt and ignition. Do you have more detailed pictures/video on it? Stream of characters / no pictures here (Firefox) right click -> open image in new tab leads to some M$ OneDrive error reading something like "this element can't be loaded at the moment".

Thank you, yes. That's what i meant by: I highly recommend the archived forum i linked in my initial post. The inverse kinematics is relatively simple with solutions that can be calculated independent of each other. Please do, this was exactly my starting point as well (without the mindstorms set lying around) This is my next goal in programming, inspired by the guy on github showing the movement of a glass of water without spilling
