  A Superb Addition to the Mindstorms Series

  I have been a huge fan of Lego and robotics for a number of years, so the Lego Mindstorms series is something that naturally caught my attention. My experience with Mindstorms started with the EV3 set. I originally purchased a set for personal use. I then used my role as a Primary School educator to introduce EV3 into classrooms. When I heard about the next iteration in the Mindstorms series, Robot Inventor, I couldn’t wait to get my hands on it. I had heard a few negative comments about the 51515 set before purchasing it, which raised a little bit of doubt in my mind that it would be a worthwhile purchase. Thankfully, those doubts have been firmly put to rest. The new Mindstorms set looks fabulous straight out of the box, You receive lots of little bags packed full of colourful parts, some stickers and a small booklet with some links. There are no instructions in the box, with digital instructions being favoured instead. The model instructions, as well as videos, code examples and the coding software are all contained within the new Mindstorms app. The app is well designed and easy to navigate. My one complaint so far would be the difficulty I had locating the Windows version, which was tucked away in the Microsoft App store. I would have expected the PC software to be easier to find for a new premium product such as this. A more visible link on the product page would help. The Mindstorms Robot Inventor kit features 5 new robot designs out of the box. Personally, I think these new robots are an upgrade on the models that come with the EV3 sets. Each robot model starts with a basic build. You then have the option to choose one of many additional activities to further develop and refine your robot. Charlie, which is the first robot I built, has ten additional activities to add to the base model including: a golf multiplayer game, a drum kit and a ski board. This new approach is a welcome improvement over the EV3 set. When you wish to start a new project, you can simply remove the additional parts/code and start again with your base model already built. This is in contrast with the EV3 kit, which only has one mode for each of the 5 robots. Once you get bored, you have to tear the entire thing down and start again. The biggest improvement that the 51515 Robot Inventor kit brings is in the coding software. The new Mindstorms app allows you to choose from Scratch or Python style coding, giving the user the option of block base coding or text based coding. This is such a drastic improvement over the coding software provided with the previous EV3 system. Speaking as an educator who has used the Mindstorms sets in school classrooms, this new approach to the coding is a game changer and will allow so many more children (and adults) of just about any ability to enjoy playing and learning with Lego Mindstorms. There are a few complaints from hardcore Mindstorms users which cannot go unmentioned. Robot Inventor 51515 does remove the option to daisy chain blocks. The wires are also hard wired rather than removable. Users will need to be more careful when pulling robots apart, because snapped cables will be a lot more expensive to replace now that they are built into the motors. It is a little disappointing that this new kit appears to be less flexible in its design than the previous EV3 was. Overall, I am really pleased with my purchase of the Lego Mindstorms Robot Inventor kit. The base package is a smart upgrade on the previous entries in the series with hours and hours of content to make and play with out of the box. This is before you factor in all of the fantastic creative possibilities that users will be able to design & make for themselves. The new coding software is head and shoulders above the previous EV3 software in accessibility and user-friendliness. I hope that Lego will continue to support the 51515 kit with extra features and add-ons for users to enjoy later down the line. Hopefully some of the negative aspects that current hardcore Mindstorms enthusiasts are disappointed with will be addressed throughout the product’s life.

  Using a 10 year old laptop updated to windows 10 and a Bluetooth 4.0 USB dongle, works fine with the new Mindstorms software. The programme supports either the Xbox or PlayStation 4 controller for use with the M.V.P. driving challenges, which makes it much easier to control than with a phone or tablet. To show it's versatility, have built the colour sorter from the EV3 set, see uploaded image. This new set as some great potential and I hope Lego keep supporting it.

  Overview

  I got this the day it came out , and I'm having a pretty fun time with it! Here are the specs of each main piece in this set: BRICK: The Brick is a net-down to the EV3 Brick because it only has 6 ports you can connect your motors/sensors with, it does not have a screen where you can test your sensors in real time (without a phone), you can only use the rechargeable battery, no normal AA batteries, so if the rechargeable battery breaks, you need to get a new one, and the Brick is not compatible with the EV3 and EV2. The good things about it is the bluetooth connection to your phone that has the coding app is down to the nanosecond when you are looking at your sensors in real time, the sounds it makes are pretty nice, you can download up to 20 different coding projects onto it, it comes with a rechargeable battery and it is much, much lighter than the EV3 Brick. MOTORS: I'm pretty sure the motors are as fast as the EV3 ones, and they are rectangular, so you can make easier shapes when you are building them. The HUGE downside is the cord, which is long enough, but if it breaks, you cannot fix it or buy a knew cable like the EV3 cords. COLOR/DISTANCE SENSOR: The cords are the same thing as the motors, and it is kind of hard to put them on your build because there isn't much connection points on them. The distance sensor can detect anything from about 40cm away, while the color sensor can only detect something from about 14cm away, so it is a small downside when it comes to detection distance. The color sensor can detect quite a bit of colors, more than the EV3 sensor (I think). LEGO BRICKS: I am glad that there is a lot more Lego bricks than the EV3 set, and there is a wide variety of bricks. You have 6 very sturdy wheels, a big red ball and a small red ball, two white rubber bands, two huge dart launchers, a 11x19 teal technic baseplate, a bunch of gears, some cool stickers, and a lot of white technic coverings, including A LOT of the usual technic peices! Also, the charging cable is not that long, which isn't a big deal in my opinion. CODING: I love how you can use Python on the EV4, and I love even more the Snap-It coding style that is much better than the different style the EV3 used. There is a wide variety of Snap-it blocks you can use, so you can do whatever you want with your EV4 set! I would have given this set a 5-star only if the cables on the motors and sensors are basically the same ones used in the EV3 sets.

  I found Robot Inventor a real improvement on NXT and EV3, with a slimmed down hub and motors and with many pieces to expand the range of activities of the five robots you can build. I've only built one of the five so far: "Charlie". I take my time in building Lego sets because I find the activity both absorbing and relaxing. The on-screen building instructions were clear and the programs for activities as you build very helpful to assure that what you had built was working properly. The further activities for "Charlie" once you had built him/it were excellent (I've uploaded five so far), and the drumming activity is especially attractive. The speed of movement provided by the motors is impressive, as are the lights on the hub for numbers and expressions. The two robots with a face are "Charlie" and "Blast", with Gelo unique for its movements and the other two being things which interact with things. Once I've finished with "Charlie", I will want to build "Blast", but to do so, sadly, I have to dismantle the first in order to build the second. The movements of "Blast" that I have seen on videos remind me of "Robocop" in the two films with that title. Could be fun to build. I think Lego MIndstorms has done a great job with this set (congratulations to the designers), and I would highly recommend it to anyone who wants to have hands-on experience in robotics at a manageable and fun level.
