thank you! The idea was to build a tinier version of the manipulator crawler (i.e. this big guy) :) Unfortunately the battery box is not sufficient to balance the arm, but it's definitely a first step! I would place further on the opposite side but the motor cable is too short.

Welcome in! hope Rome is treating you well :)

What an amazing design! Very neat and ingenious. I might have a look at your stud.io files to learn a few tricks.

Thanks, Glaysche. I presume that I am also going to follow that path (or rabbit hole) :P Do you have a link to your robotic arm?

So, time for a quick update! I redesigned the tower and the horizontal part of the gripper arm. This allowed me to put the battery pack and one of the gripper motors somewhere where they can actually counterbalance the weight of the gripper In order to move the gripper motor, I had to introduce a system of axles. I'm not entirely happy of how it turned out (there is a bit of backlash) and I still haven't secured the motor, but here is a preview: Furthermore, I changed the mechanism responsible for lifting and lowering the arm. This new system doesn't have any hinge, relies on gravity to lower the arm, and looks a bit silly. However, it provides a wider range of heights: I also moved the motor driving the rotating platform so that it sits vertically: Feedback and suggestions are very very welcome! :)

Yeah, I also thought it was weird. I now added BBcode thumbnails with links to the original files.

Hey everyone, I'd like to show you my very very first attempt at a MOC, using pieces from the Liebherr excavator. My main source of inspiration for this comes from the legendary manipulator crawler MOC which I very much enjoyed building. However, I felt like I wanted something a bit smaller and more agile to serve me coffee in the morning or mop the floor (disclaimer: it can't really do any of this yet :P). The vehicle features 2 independently driven tracks (1 L-motor each), a panning tower section (1 XL-motor), an arm that can move up or down using a simple parallel lever system (1 L-motor and 2 linear actuators), and a scissor-like gripping mechanism ( XL-motor and a tiny linear actuator) that can rotate freely (1 L-motor). The motors are controlled using 2 hubs: the one in the platform controls the first 4 motors mentioned, while a second hub in the tower section handles the gripping arm retraction and rotation. Overall, I'm quite satisfied with the base (especially the cover for the hub) and the gripping mechanism. The tower section and arm are still WIP. These are the things I'd like to improve: move gripper motors closer to the tower for better weight distribution and to reduce fatigue on the actuators smarter arm lifting mechanism with increased range of motion make the second hub more accessible Here are a few shots (please let me know if I'm breaking any rule with regards to posting pictures etc). I know that the idea is not the most pioneering one but I have to start from somewhere, ehe. Hope you enjoyed it, looking forward to feedback and suggestions for improvements!

Welcome in, BananaBrick! best of luck with your idea submission, it looks really cool!!

Hey Lena, welcome here. I work with machine learning myself, and your app is very impressive! Must have been hell collecting and labeling all the training data :P

These might not be legendary or pioneering sets, but they're still on my personal bucket list of sets I want to build : 42055 Bucket Wheel Excavator: novel concept (especially for those jaded with cars and trucks), plenty of features using only one motor, and lots of parts for MOCs and mods, though I'm not a big fan of the color palette there. 42110 Land Rover Defender: it just looks so smooth and detailed, makes for a great showpiece 42128 Heavy-Duty Tow Truck: pneumatics!!!

Thank you, Feuer! :)

Hey everyone! I recently decided I was going to spend my disposable income on lego bricks (or, in my case, liftarms and axles) so here I am. I write from Denmark, though I am originally from Italy. Being the geeky/engineer guy, I am mostly interested in Technics and Mindstorm themes. I'm trying to get a hobby that doesn't involve coding in Python, but let's see about that. I started my collection with the 42100 and 42114, which together account for a whole lot of pieces. No, I haven't mixed them up yet ;) Right now I'm working on a small tank/robot thing out of the Liebherr, I hope I can post it soon. That's it for now. I look forward to meeting fellow AFOLs, getting inspired by your MOCs, and sharing my own.
