In which I recall making models move in simpler times, invest in a LEGO Boost Creative Toolbox set, and set about meeting Vernie the robot. This article is as much for the beginner, trying to understand where to look for information, and finding out what my personal experience was like with the first couple of models. In the future I will build some more, and look at the programs involved along the way.
As life progressed, I graduated to the 181 train set: a black motor brick, with a dedicated battery box in the tender, running behind the engine. There was an additional switch below the battery box, which allowed a raised railway signal to stop the train. Somewhere along the road we found some coloured gears, and simple motorised machines became an option. Then came the Technical sets, with their single drive shaft motor, and optional gearing boxes. I have already written about these early Technic experiences this year.

So, when I heard about LEGO Boost, I became quite excited. LEGO Boost is a brick based (rather than Technic) robotics system with 3 independent motor channels, as well as a light and distance sensor brick, and an inbuilt tilt sensor, designed to be programmed by a 7 year old with some form of tablet device. Perhaps this would be something I could use in the not too distant future to motorise my models, or introduce a level of interactivity into them.
I first experienced Boost during the LEGO Fan Media Days in June 2017. Carl Merriam, one of the model designers, demonstrated some of the models and answered some of my questions about what was going to be required. Boost was released to most of the world in August 2017, and arrived in Australia in October 2017. It is dependent on an app, running on a capable tablet, to be of any significant use. Otherwise you have just $250 on a paperweight and some additional elements. Fortunately, the App has been available since the global release in the Apple App Store, as well as the Google Play store, and was available in Australia before the set was. I hope this is the case in all markets, but I notice that A Chinese language version is due to be released early 2018.
Of course, this does not mean that people have not tried, and there are now multiple alternative platforms for programming or controlling your Boost, be it using a smartphone or laptop with an alternative programming environment such as Scratch. This is beyond the scope of my expertise, and I will not attempt to include it further in the discussion. However, if you look, I suspect you will find things.
The bags are numbered for the purpose of constructing Vernie the robot: each numbered bag appears in order to build up each aspect of this happy little robot. Every couple of bags we take a little time out to do some programming exercises.
There are 850 elements, including the specific Boost Elements: The Move Hub, the servo Motor, the sensory brick and the required cables. The cable connections are different to those used in either Power Functions or Mindstorms sets to date, but are similar to those used in the WeDo 2.0 educational robotics platform.
Before starting work on Vernie, we build a simple wheeled platform to demonstrate the ease with which a motorised vehicle can be put together and programmed. I have a wheeled hub, with the other moot on top of it. I ask it to move, and to does. It even turns. Much Joy. Achievement unlocked.
Vernie is the hero model for Boost: an anthropomorphic robot on tracks, Vernie is so important as a starter model for BOOST that the bags are numbered in order that they are required for building him. The build was a little longer than I initially expected: probably 3 hours from start to finish, taking time out every few bags to run through some of the coding examples that you are encouraged to do.
Bag by Bag, Vernie gets built up: Torso, head, tracks, arms, hands and fashion accessories. You know, like sunglasses, a bow-tie and a microphone. Because any good robot needs to be able to do standup comedy.
The colour blocking also works really well: while the colour palette is limited, the instructions are designed so that the majority of adjacent parts are in contrasting colours, which makes for a better experience when working with the aid of a tablet screen for construction. It made it much harder to position a piece one or two studs out of line. I really appreciated this feature as I built this first model.
Vernie is a great introductory model, but while he is easy to put together, with elements in a bag per step, perhaps some care needs to be taken while dismantling him. I highly recommend keeping the Boost elements separate from the rest of your collection, especially if you are intending to put together the other models.
To this end, I went to my local hardware shop, and picked up some plastic containers. I could have done better, but am pretty happy with how I have it sorted. This sorting system works for me, but we all have our little ways. I will probably refine it as
I have only begun to scratch the surface with LEGO Boost. The coding exercises encourage experimentation, and are simple to complete. If you are looking to create a model that is open to user interaction, then Boost is a great place to start. With a wide variety of elements, both Technic and System, this is a great set for starting your LEGO Collection. You may not like the tablet restrictions, and it may be a bit tedious to work through all of the examples, but if you persevere, over time you will develop a good idea of how the coding elements work together. One of things to consider when purchasing Boost might be a set of separate sorting boxes, if you wish to keep the elements together.
I am looking forward to visiting some of the other models in the near future, and will present some of their interesting features here. For further information, there are a number of Facebook groups and communities dealing with LEGO Boost, as well as additional information available from the LEGO Boost FAQ Page.
I have covered this in a recent article. It is possible to unlock activities/ instructions, and also to access the most basic of the programming blocks (atomic level programming) Check out -with-boost-driven-to-distraction/
I have a similar problem, ours did a firmware update first though. Now it will not connect to any device... I have tried 3 android phones and the Nordic Semi nRF connect app and there seems to be no BLE signal at all from the boost hub.

I have been able to install the Lego Boost application on Android 5.1.1 (Kernel 3.4, BTLE 4.0), but was not able to pass the first couple of pop-up screens in the application. The application requires a successful connection with the Move Hub over BTLE before giving access to the building instructions.
Went into this and spent a few hours to figure out how to solve it. I will leave a possible solution.In my case I was using 3 different phones: Iphone 6s & 8, Samsung S9Lego Boost app ver: 1.9.7Fw ver: 1.0.00
I had similar problem with lenovo tab 2 a10-70. First problem was that BT can not connect to lego boost, because tablet was connected with BT to external loud speaker. I had to disconnect device.Second problem was that boost denied upload programs until firmware update.Problem was that BT modul ver 4.0 work with boost, but it is not able to update firmware in the brick. I had to install lego software on newer phone and made update this way.
The Lego Boost is designed to be run from an app on an Android or iPad tablet, using a graphics programming language not unlike Scratch. It makes a good job of this and is easy for kids to pick up, but these sorts of languages have their limitations. They can be inflexible and difficult to read, especially as the code gets bigger. By using Python, much more complex programs can created, many that are not possible with graphics-based code. So, give your Boost a boost by letting Python do the controlling.

The bulk of the documentation is in the README.md file and we found that not all of it works with the Raspberry Pi. But, it does contain some short single-function examples. Basically, to get the Move Hub to do things, you send it a command, as you might expect; however, to get information back from the Move Hub, you have to subscribe to the appropriate stream. When you do, you specify the name of a function that will be called when there is new data from whatever sensor you subscribed from. You must unsubscribe from the sensor before your Python program finishes.
After the green button is pressed, the distance sensor is tested; this repeats for 100 measurements. You can change the distance sensor reading by waving your hand in front of it: it returns a value in inches, to the nearest inch, for distances above one inch; for smaller distances, it returns finer values. The program converts this into millimetres for display. The tilt sensor tests require you to pick up and turn the Hub, and the motor angle read requires you to turn the motor wheels by hand. When no movement of the wheels has been detected over the last five seconds, the demo ends. 152ee80cbc
