Wow, that’s amazing! Is there a name for this walking mechanism?

[@Jiangquan1982]

Thanks for your amazing work. Can you please tell me how to use your lms file? I cannot open it.

[@greenfridge7074]

Hey Quan Jiang, thanks for the feedback!
I'm not sure if the file works across all platforms, but in iOS i can just open it directly with the Lego robot inventor app. Does this help?

[@Jiangquan1982]

Thank you! Will try it.

[@louishere5236]

Sorry, but this file( that you has leaved for your “watchers”) cannot be opened by me on phone( I can not download special app for robot inventor set on pc because of strange error, can you help me?( I only need a piece of code that contains instructions for robot how to walk straight), thank you for this amazing robot and amazing idea, good luck

[@greenfridge7074]

Hey LOUishere, i uploaded a screenshot of the code so you can copy the parts you are interested in. Here is the link: www.dropbox.com/s/5c45z8xxyzigg8u/IMG_9428.PNG?dl=0 I hope this works for you! :)

[@louishere5236]

Thank you very much for your answer, it is smth that I am needed in

[@glebsilenko]

Спасибо, круто получилось.

[@creative_constructs-g6o]

I can tell you workout by how veiny you hand are 💪🏾😂

[@mikefpv0]

Thanks! It works perfectly. But there must be importance for detais. I install the hub in wrong side and this makes everything unworking.

[@Ttevere1214]

Bro I need to build this in my class and program it but I was able to download the program with a lot of effort on a iPad

[@creative_constructs-g6o]

Wait, is this greenfridges alt?

[@greenfridge7074]

Hi, sorry, but i don't understand. Can you explain please?

[@creative_constructs-g6o]

@@greenfridge7074 oh sorry, yt was glitching a bit. It was showing me the video but said that it wasn’t yours. Idk why? But I thought it was one of your other channels. Btw nice design!

[@theperfectbotsteve4916]

im gonna try and make it remote controlled

[@inspirecodeteam]

I build that but I don't know which one is wrong. When he walks a leg is automatically broken. I find that fault but I don't see it. And also the other leg sticks and doesn't move while walking.
Help!

[@greenfridge7074]

Hey Smart Creations, did you check if any moving part inside touches something? The white parts to mount those yellow axles on the motorplates are not optimal, but i found no better option in the set, so you have to make sure they are orientated in the right direction to not touch each other or some other part while moving. If that does not help, maybe you can upload a short video of the accident happening. :)

[@inspirecodeteam]

@@greenfridge7074 Yes, the yellow axle push the white part and it stuck.

[@Dimosthenis_Gkemitzoglou]

Hello! Can you please tell me how to programm this robot?

[@greenfridge7074]

Hello! You can download the programming. The link is in the video description :)

[@greenfridge7074]

And if the file does not work for you, you can find a screenshot of the whole program here:

[@Dimosthenis_Gkemitzoglou]

@@greenfridge7074 thank you very much for your help! Whenever I press the right/left button, it goes to the right/left, instead of rotating right/left. And when I lift the right/left side, it rotates to right/left side. Also, it doesn't go forward or backwards. By the way, do I have to place rubber items in the feet?

[@greenfridge7074]

@@Dimosthenis_Gkemitzoglou This could have various reasons.
You could check if:
- the coding is really correct.
- the motors are connected to the right slots of the hub with the right letters, like in the video.
- the pins that connect the yellow cross bars to the motors are always in the marked hole of the motor.
I hope this is helpful for you :)
