A pneumatic system does not really need to detect endpoints. 42100 needs to be calibrated for 2 reasons - one is to be able to use the visual controller matching the actual position of the arm and the bucket, the other is to avoid engaging the actuator clutches. With the motors controlling the pneumatic valves there's no option for a visual controller but they don't need any protection either. But such system with the 4 pneumatic functions would require 4 tacho motors, I think it's quite an overkill to add 4 Large PU motors just to control the valves. It'd be a great opportunity to introduce a micro motor for the PU system :) Anyway, it'd be quite refreshing to see a set with RC pneumatics instead of putting the Liebherr setup in a different form factor.

Yes they do :) Just a few minutes of work: -

IP = Intellectual Property In this case it simply means that it will be the LEGO version of a real-life branded vehicle. -

@Bartybum sure, you can add buttons to adjust the logical 0 position. It is planned to be covered in one of the following tutorials. -

If you want to build a control profile in the Powered Up app that actually makes sense, here's a step by step tutorial: -
Technic 2021 Set Discussion
kbalage replied to LvdH's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Considering the price point of the much smaller sets with Powered Up components I don't think too much would fit in that price, and there'd be too many motorized sets anyway. I would rather like to see a modern interpretation of 8285 with only manual functions. -

According to the catalogue the release is scheduled for March -
If you check the video at this point you will see that they do touch the mudguards. There's a reason why LEGO designed the set this way, this mod is for the ones who prefer the look over the functionality of the suspension.

Problems with the Technic Skin

Thanks Jim, Eurobricks addicts started to get worried :D -

Same for me... @Jim are you aware of this? -
51515 uses a 7.3V battery pack, you can check the detailed documentation here. I don't want to disappoint you but the 18+ product line is more of a marketing gimmick then a real will to develop specific products for adults. There are some like the Art series, but I highly doubt TLG would invest serious resources to develop a high power system with specific more durable parts and electronics. Just take a look at the development of Powered Up, they are way back behind schedule with a system that has a much wider target audience. Realistically you can expect a rechargeable battery pack coming for Powered Up, but I'm almost sure that'll have a limited voltage around 7.2V.

I was quite surprised to see the level of outrage caused by the lack of differential among the comments... the design of the rear section is quite unique with the different angles used and a differential simply does not fit there easily: I know the current setup with the gears is not realistic, but honestly the rear wheels driving the fake engine is not realistic either so I don't think that should be a dealbraker. The set is perfectly playable with this setup and that matters more for the target audience. -
Not directly, this unit is designed as a replacement for the battery holder and the bottom cover of the AAA PU hub. From a functionality perspective it gives you similar results (apart from the higher voltage) like the rechargeable PF battery box. A proprietary rechargeable battery that can be used only for a specific system is not very eco-friendly compared to the generic rechargeable AA/AAA batteries that are versatile and can be recycled properly. Well I would not call the app primitive, it is definitely more flexible than anything that was offered by LEGO for Power Functions. Most people think the Powered Up app is actually too complicated and only targeted towards people who are familiar with coding, I wish it had a much simpler interface/option like the BuWizz app for a quick and easy to use control setup. LEGO will never release anything beyond 9V. Even with that voltage you can easily create a setup that brakes the plastic, and with higher voltage there's even a bigger risk of that. LEGO motors are (more or less) safe to use up to 12V, but that is already well beyond the "toy for kids" concept so I think it's better if only 3rd party companies are offering it for people who know and understand the risk.

There's a rechargeable battery replacement solution for the AAA hub that you can also power externally: https://keybrick.one/

As I mentioned in the video this set was not sent by LEGO as I managed to buy it in a local shop earlier. In such cases we are allowed to publish earlier than the official embargo, obviously with a proper proof of purchase and a legit source (no Ebay, not fallen from the truck or smuggled from the factory etc). -
LEGO has 3 types of motors in the PU range. "dumb" motors with no encoder and only power control, like the 45303 Simple Medium Linear Motor or the 88011 Train Motor motors with encoder but only relative positioning for speed/power control, this one only knows it's position relative to the "power on" position so the usage as a servo is limited, like the 88008 Medium Linear Motor (Boost) motors with encoder and absolute positioning, these motors have a physical 0 position and can be used as a servo, like the 88013 Technic Large Motor or the 88014 XL motor About the "linear" in the name I only have guesses - there's now an "angular" motor type that has the driving axle perpendicular to the longest side of the motor, so the "linear" might be the one that has the regular driving axle setup.

Here is my building review of the set, I have to say that I liked it very much (but I still hate to apply stickers ) -
[APP] BrickController2
kbalage replied to imurvai's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
What does it do exactly when it is jammed? If it turns to left ot right by itself and stays there then it's not related to the app directly, does the same with Control+ as well.- 1,316 replies

You need to create the code first in the app for the control profile, mapping the PU remote's buttons to the hub's outputs (basically the motors). Both the hub and the remote needs to be connected to the app for this. Next time you want to use the remote with that vehicle, you load the profile in the app and you connect both the hub and the remote to it. You press play and you are ready to go.

The Powered Up remote offers the same functionality as the small PF remote, but with buttons instead of levers. There's no easy speed control, but that was not offered with the small PF remote either. You can configure the Powered Up app to use the PU remote as an input and you are ready to go, this should work for most vehicles. For trains it works out of the box with speed control. I would also like to see proper remote with proportional joysticks for PU, let's see if it happens or not. But considering the implementation of the Ps4/Xbox controllers in the Mindstorms app I think we can expect something similar for PU in the future instead of a proprietary design. That solution would still require the smart device as a bridge, but the usability would be greatly improved.
