Finished: Proof of dimensions W x L x H = 13 x 37 x 20 = 9620 cubc studs Making itself useful:

The cylinder stays in place pretty well, but the tube was a problem. I'll try to change that to get rid of the elastic bands because it really spoils the view.

Pneumatics done (just need to find a better solution for the elastic bands; that looks pretty bad):

Looks interesting. Good luck keeping within the 10000 cubic studs.

Thanks for the feedback Erik. The following pic gives an example of what I have in mind. These front outriggers do extend a bit horizontally but not a lot. On this scale I don't think I'm capable to replicate that effect.

There is.

I hope a cherry picker classifies as "construction equipment". First time for me to make a MOC with pneumatics, so not sure yet if I'll succeed. Bottom part with outriggers. Earlier versions had a problem that if you would put a pneumatic pump on the vehicle and press it in the outriggers would just collapse under the pressure ;-) Current version has one worm wheel per outrigger and that seems to be strong enough. The boom: Extended: Red knobs right in front of the rear wheels will be for the outriggers and the turntable: A potential issue might be that I'll fail to keep it within the maximum 10000 cubic studs. As it will be 13 studs wide and probably 40 long I'll have to keep it to a maximum of 19 studs in height (13 * 40 * 19 = 9880)

Is a cherry picker considered construction equipment our is that just outside of the allowed category?

On the upside you'll have more time for MOC's then. Looking forward to your life sized Mindstorms robot!

Amazing work, this should be an official Lego set. Didn't know you could use that remote with those hubs; guess I'll definitely have to check out PyBricks (as I don't really like controlling with my phone). Great humor: fish tank, atom bomb next to each other. Also great that you made the instructions freely available although I won't be able to make it myself as I'm missing most of the system parts.

I agree, a large passenger or freight plane would be very a very repetitive build with lots of the same parts. I think it's really unlikely we would ever see something like that in an official technic set.

Generating sine waves using gears; never thought about that. Really brilliant work, hope to see more of this in the future.

Don't have the set but I noticed I had (almost) every part, just not in the right color. Result is a Porsche with an identity crisis:

Also by far the part that I had most trouble with getting it right (went through a dozen iterations). If you look at for example a Huss Enterprise, that has only one tilting arm, but then the arm obviously has to extend much further. Physics don't scale well ... The speed is controllable (see for example the starting phase), but if you go too slow then the benches don't go outward like you would expect them to do. In real life the number of revolutions per minute is of course slower:

Finally a video (sorry, quality is not great. My phone has the better cam but I need that as a controller):

Can you have one motor/servo that selects a function, and then another one that provides the drive of that function? In other words not a single transformation movement, but multiple consecutive steps.

They would fit but fly out, which is not very comfortable (but might result in some nice video material). Will check if I find some way to fasten them.

This is my second attempt of making a funfair ride like the Reverchon Explorer For TC14 I already did an attempt to make a ride like the Explorer, but since then my collection as well as my skills have grown a bit so I decided to give it a new attempt: It's pretty big, new tow crane for scale: There are 16 of those seats, each capable of holding two passengers (original ride has 20, but this way it's already big enough): The middle part lifts and tilts the wheel in a way that the seats on come very close without hitting it. This was by far the hardest part to get right: The middle part rotates slowly in the opposite direction of the wheel. This way where the top and bottom of the wheel are is constantly changing, creating a "dancing movement": The mechanism: the middle part rotates (slowly; 1 XL motor in the bottom), on top of that are two linear actuators (each powered by an L motor) that provide the lifting. Another XL motor at the top is responsible for the rotation of the wheel. Another view of the middle part (wheel in lowest position): This is by far the biggest (in number of parts) thing I've ever made and I'm pretty proud of it. Of course the only way to properly show how it looks in motion would be a video ... which I screwed up. I will make a new one and upload it, but that might be for next weekend. Hope you like it, all comments, criticisms, and suggestions are highly appreciated!

Of course if the others are running, but could there be an effect of just other motors being connected and not running?

Is the amount of power that the control+ hub sends to the motors dependent of the number of motors attached even if others are running? It seems so in my case but it doesn't make a lot of sense to me (using the Buwizz app). Update: my bad, turns out I was just putting too much stress on that one motor; had nothing to do with the amount of other motors connected.

Did not buy it, but interesting for some: 42131 Cat is listed at €369 at Dreamland Belgium, AND until the 7th of November you get 20% off if you buy for €50 or more in "toys". So that's 369 * .8 = €295.2 or 2/3th of the Lego list price! https://www.dreamland.be/e/nl/dl/lego-technic-42131-cat-d11t-bulldozer-111267

Only needed to watch it 10 times before I understood how you managed to control 14 segments with 7 motors. It's really great, but I love the "elegance" of the Version 2, so I'm really looking forward to a Version 2 based 14 segment ;-)

So impressive! Also impressive it the fact the your Lego storage seems to take a whole wall!

42100 (Liebherr 9800) can easily be found for less than €350 so it's not really a fair comparison against for example the 42131 (CAT) which is just new.

This is what I'll remember from the review. For me this is one of the least inspiring sets. The Skid Steer Loader (42116) has more functionality than this.
