With the launch of the new LEGO Power Functions 2.0 (now referred to as LEGO Powered Up) system in the #60197 LEGO City Passenger Train, #60198 LEGO City Cargo Train, and #76112 LEGO Super Heroes App-Controlled Batmobile, a lot of questions and concerns surfaced from the LEGO fan community. Ambassadors of the various recognized LEGO fan groups were asked to gather and submit questions from their members, so the LEGO Powered Up team can answer them. Below, I have included a summary of some of the topics that was discussed, and you can read the full discussion in this LEGO Ambassador Network blog post and comment section. 🙂
In response to questions about renaming LEGO Power Functions to LEGO Powered Up, the LEGO Powered Up team confirmed that although initially they used LEGO Power Functions 2.0 as the name of the new LEGO electronic building platform, they now refer to it as LEGO Powered Up.
The LEGO Powered Up platform was designed to replace LEGO Power Functions completely, and also reach into other product lines that used different electronic systems. Current products using elements from the LEGO Powered Up platform are as follows: LEGO WeDo 2.0, LEGO BOOST, LEGO City trains, LEGO DUPLO trains, and the LEGO Super Heroes App-Controlled Batmobile. All new electronics sets from now on will use the LEGO Powered Up platform, including LEGO System sets, LEGO Technic sets, LEGO DUPLO sets, and LEGO Education sets.
While some of the components of the new platform look very similar to LEGO Power Functions (i.e. battery box, motors, etc.), there are some significant differences that make the two systems incompatible; the wired connections have different connectors, and the wireless connection uses Bluetooth instead of Infrared. (This wireless connection is used both between the physical LEGO Powered Up elements, and for connecting to mobile smart devices.)
There were a number of questions about LEGO releasing adapters to make some of the LEGO Power Function components compatible with the LEGO Powered Up system. The LEGO Powered Up team had no plans to release adapters, however due to much concern and criticism from the community about this, they may reconsider. (Note: the two power control wires of the old 9V system, LEGO Power Functions, and LEGO Powered Up have the same function across the three platforms.)
There were also questions about the physical connections of the LEGO Powered Up platform, like incorporating more than two outlets on the battery box, and being able to stack connectors (like in the LEGO Power Functions platform). The LEGO Powered Up team is still working on further developing the new platform by adding new components and functions, and they did not go into detail answering these questions. However, they did explain that the reasoning behind not using stackable plugs was to enable more intelligent interaction through the wires. An example of this is that all elements can now be electrically identified, so when attaching e.g. a train motor, the LEGO Powered Up hub and the LEGO Powered Up app can recognize it as a train motor. This allows younger users to easily put components in the right place. Another benefit is that LEGO can optimize functionality based on particular elements. For example, when using a train motor or an add-on light, the handset increments/decrements power (good for trains/setting lights), but when using the medium motor, the handset sets 100% power when a button is pressed down (good for RC vehicles).
Questions about the limitations of the remote control versus the app were also asked. For the LEGO City trains, the app can provide sound-effects for the trains – something that the remote cannot do. The LEGO Powered Up team responded that although this function is not fully developed yet, the remote can connect to a smart device via Bluetooth, and you will be able to give different functions to the buttons via the app.
In regards to how many LEGO Powered Up hubs a single remote can control, the LEGO Powered Up Team shared that you can link up to five devices together. With a mobile smart device, the current limit is up to ten hubs, but this is device-dependent. As far as how many motors you can control with a single hub, with the Smart Move Hub 2 I/O used in the LEGO BOOST set, you can control up to four motors (two internal and two external), and with the Smart Hub 2 I/O, you can control two external motors.
An interesting feature of the LEGO Powered Up system is that if you build two or more hubs into the same train, and give them all the same channel color, you can drive up to five train motors in sync by connecting them to the same output on each hub. This is especially useful for long trains. In addition, you can use two motors at the same time from the same controller with one motor having its polarity reversed. This is done by turning the button interface to the direction of control needed. This feature is very handy for operating vehicles where you want vertical control for forward/backward drive and horizontal for steering.
Some reviewers reported that the range of the Bluetooth connection was only 3-4 meters, even though the advertised range is well over 10 meters (although this can be limited by factors such as electromagnetic interference). The LEGO Powered Up team will look into these reports and see if they can figure out what might be the problem. When the hub and controller are out of range, the connection gets lost, and both devices go into standby mode with a blinking white LED. Any running motors will get turned off. Unfortunately, it’s not possible to elect to keep the motor running while there is no connection, even though this would be very useful for trains. In addition, if you are using the app, and your smart device turns off/goes on standby, motors will get turned off as well. When the hub and controller are back range again, the link will be reestablished. The good news is that each of the network connections runs on a unique address, so another controller can’t highjack your network. In addition, these network connections are remembered even after the connection gets lost.
There were also questions about the compatibility of the LEGO Powered Up components in different systems, like LEGO BOOST, LEGO WeDo, LEGO City Trains, etc. Some of the questions were as follows: Can we use the LEGO Powered Up remote with the LEGO WeDo hub? Can we use the LEGO Powered Up remote with the LEGO BOOST hub? Can we use LEGO Boost / LEGO WeDo sensors with the LEGO Powered Up hub? Can we use the LEGO BOOST / LEGO WeDo / LEGO Powered Up app to control any of the other platforms? The LEGO Powered Up team responded that the aim of the new platform is that all the wired and wireless components will eventually work together. However, some of these connections are not implemented yet and will come through firmware and app updates. Please note that the LEGO Powered Up system does not work with LEGO Mindstorms, and there was no mention of making them compatible in the future.
In response to questions about the electrical characteristics of the system, like maximum current at the outputs, minimum and maximum voltage at the outputs, torque of the various motors, and how these compare to LEGO Power Functions 1.0 components, the LEGO Powered Up team stated that these will be shared later this year.
As far as powering the LEGO Powered Up system, the Smart Hub (used in the LEGO CITY trains and the App-Controlled Batmobile) holds 6 AAA batteries, and the Smart Controller holds 4 AAA batteries. Rechargeable Lithium, NiMh, etc. batteries can be used instead of traditional batteries. According to the LEGO Powered Up team, the power consumption of the old and new platforms is comparable.
An interesting question was about how reliable the system is in an environment with many active controllers (school setting, LEGO convention, etc.). The response from the LEGO Powered Up team was that the new platform can be used in an environment with many active devices. With LEGO WeDo 2.0, they have seen over 45 active independent networks working fine without noticeable impact to model action/reaction.
There is also concern about how long the LEGO Power Functions components will be available for those who want to stay with the older system, and when will they get completely replaced by the LEGO Powered Up components. In response, the LEGO Powered Up team assured fans that LEGO Power Functions will be available for some time and won’t suddenly disappear from stock. There will be a period of time where both systems will be available, until the older system gradually gets phased out. The new LEGO Powered Up components should be available individually at the beginning of 2019 at the Online LEGO Shop.
Reading the questions, answers, and follow-up questions, it is clear that there are still some concerns that need to be addressed. The LEGO Powered Up team did test the new system in workshops with LEGO train fans to ensure the best solutions, and they will continue to be in dialogue with the LEGO train and LEGO Technic fan communities to see how to improve and expand the possibilities with the LEGO Powered Up platform. This is especially important for the smooth continuation of LEGO train shows and LEGO Great Ball Contraptions, as well as for children to be able to transition their older trains over to the new platform.
If you are interested in the new system, I encourage you to read the full discussion at this LEGO Ambassador Network blog post and comment section. And, if you are curious to try out the new LEGO Powered Up platform yourself, the #60197 LEGO City Passenger Train, #60198 LEGO City Cargo Train, and #76112 LEGO Super Heroes App-Controlled Batmobile are available at the Online LEGO Shop.
