I am a seasoned RC vehicle veteran. Over the last several years I've owned and operated nearly 50 different RC vehicles, ranging from basic starter trucks all the way up to $500+ vehicles. My experience with RC vehicles led me to a Parrot AR.Drone, which has a few features on it that allow it to fly somewhat autonomously. These autonomous features made me start looking into ways to make a regular RC truck more autonomous, which of course led me to start looking into robotics. Years ago, when the very first LEGO Mindstorms set was released, I actually purchased one. Upon getting it home, I decided that it was probably too advanced for me, and I ended up returning it. Fast forward to this year. While looking into ways to start getting into robotics, I headed to the store to buy a Robosapien X. Although basic, the Robosapien X seemed like a good place to start with robotics, as it had a basic way of being programmed, and it had some options for modifying it to add features and accessories. While at the store, I saw the Mindstorms EV3 set. I was immediately in awe, as the box just draws you in. I liked the looks of the models that it was showing, and knowing LEGO quality I knew it would be a product that functioned as good as it looked. It was a bit pricey for me, so I passed on it initially. A few days later, I kept thinking about the EV3 set, so I just went ahead and ordered one on Amazon. It arrived quickly, as is the case for most of the things shipped from Amazon, and I was all set to get started. Upon opening the packaging, you quickly realize that the outside sleeve is a "course" for the robots that you are going to build to navigate on. It's a nice feature, and a good way to include something like this. The cardboard is more sturdy than just a poster that folds up, so it seems like it will last longer than if it was made out of regular paper and included in the box. After getting the box open, I started inspecting the things that were included. Lots of parts, the motors, sensors, and that all important "brain" type of brick. The instructions included are for building the first model, which is called Track3r. I set about following the instructions to get the Track3r built. It was a fairly quick build, with no real issues that popped up. As is always the case the instructions were clear and concise and didn't leave me guessing at any point. After getting the model built, I headed to my PC to download the EV3 software, which installed quickly and easily. I then went about following the instructions for setting up my first program. Now, I'm pretty tech savvy...however, I've never really tried any kind of computer programming. This was the part of the Mindstorms EV3 kit that had me a bit concerned, as I wasn't sure if I was going to be able to wrap my head around it. Luckily, the LEGO programming method is extremely easy to use. It's a graphic system where you drag and drop "blocks" that serve as the commands, and then in those blocks you change settings in order to change what the robot will do when it reaches that portion of the program. In a matter of minutes I had the first program written and installed, and the robot very quickly did exactly what it was supposed to do...it moved forward, spun a blade and knocked a tire off of a spot, then moved back to the starting point. I was impressed. I had managed to program a robot all by myself, and it didn't even seem to frustrate at all. Over the next several days, I continued using the EV3 software to progress through the different models and "missions" that went with the Track3r. I continued to not have many problems with the programming, and by about the third mission I realized something...the LEGO EV3 software was slowly, subtly, but surely TEACHING me programming. Each mission was bringing new variables to the table that required different programming blocks and options. It was so subtle that at first you don't even realize that you're being taught something, and to me this is ingenious. Any time learning can be disguised as fun, I feel that it's something that will be more easily recalled and will be something that people WANT to continue to do. After the first four missions, before even progressing to the final mission with the Track3r, I decided to give it a go at creating a program completely from scratch. What I wanted to do was effectively "reverse" the Track3r, so that it's back was it's front and it's front was it's back, so that it could use the IR sensor as an "eye." I then wanted the Track3r to move around on it's own, and when it came into a certain proximity of an object it would back up and turn around, then continue going. It took me a little while to figure out a couple of the functions, mainly because I wanted the speed it reversed and the amount it turned to be "random," but with the help of the great Mindstorms Community on LEGO's site, I was able to figure it out...and in fact, I figured it out while waiting for a response from that site, but then used the response just to check my own work. After about a night worth of work, I had managed to create a program that had the Track3r roam about on it's own. Whenever it would get within about 8" of an object, it would back up (at a random speed), growl, turn around (a random amount at a random speed) and then move forward again. With this program, the Track3r is effectively able to just autonomously roam around the room and not get stuck on anything. Success!!! I had built a robot, and programmed it myself with a program that I had built from the ground up. I've had so much fun tweaking and adjusting this program that I've made, that I haven't really felt a need to move on to any more of the models. That's not to say I'm not looking forward to moving on to those other models, I am, and I probably will start a new one this next week...but the ways I've been able to slowly tweak my program to do EXACTLY what I wanted it to do has been a lot of fun for me. I believe that even though I've only gone through a small portion of what this set has to offer, I'm already convinced of this set's awesomeness. This is, without a doubt, the best LEGO set I've ever had...and, dare I say, one of the best products I've ever bought, period. Is it pricey?? Absolutely, but I believe it is worth every penny. I've had so much fun with the first set of builds for the Track3r that I feel I've already gotten value out of the kit...and the fact that I have a ton of stuff left to do before I even start moving on to ground up models with ground up programs just says to me that this kit's value is through the roof. Highly, highly recommended!! Read more

動画にあげたTRACK3Rは、取扱説明書(組立図)が紙ベースで入っているので、１時間ちょっとで完成しました。 これからパソコンを使って他のバージョンやセンサーを使ったオリジナルが作れると思うとワクワクします。 細かい部品が多いので、お菓子の箱(底の浅いもの)なんかが4個〜5箱あると作業時間が短縮できると思います。 Read more

You can even daisy chain the controllers together to make really complicated robots (a good excuse to buy another kit right?). It's lego. it's awesome. It's not cheap, and it eats batteries pretty quickly, so buy some rechargeables or drop the nearly $100 on the lego battery that can be charged in place, but like I said. It's a lego robot kit and it's awesome. Read more
