LEGO Mindstorms: The Master's Technique

Poomah writes: "I started my LEGO building career in the late 60s with the basic bricks of that time. I built anything that came to mind. There was no end to the wonders I created with those basic bricks. As I grew up I strayed from the LEGO path to do things like going to college, getting a job, and getting married so I could start a family. When LEGO Mindstorms was released, I was one of the first in line to get one." Now he's discovered a book to help people get the most out of these toys, so here's Poomah's review of LEGO Mindstorms: The Master's Technique. LEGO Mindstorms: The Master's Technique author Jin Sato pages 361 publisher No Starch Press rating 9 reviewer Poomah ISBN 1-886411-56-5 summary How a master builds a LEGO MINDSTORMS robot.

I devoured the book, performed all of the challenges and even amazed my friends with a few inventions of my own. From time to time I would see some inventions spotlighted online. I would marvel at the time and dedication people would put into these. I would wonder, like many others, how someone would conceive such things as a copier or a Rubik's Cube solver. Now there's a book that explains LEGOS from the mind of a master and an engineer of 25 years: Jin Sato's LEGO Mindstorms: The Master's Technique."

When I first looked at this book I was so excited. It would give me the excuse I would need to play with my LEGOS once again. It even has a cute LEGO doggie on the cover. Wait a moment, that cute doggie uses two LEGO Mindstorms kits. It has two RCXs. I only have one. Is this book going to be of any use to me, the casual LEGO builder? Simply put, "Yes!"

Jin starts the book at the most logical place, the beginning. A quick one-page history, one short chapter on the LEGO bricks themselves. This includes info on what they are made of, some of the evolution of LEGO into TECHNIC pieces, and how to assemble them in different ways to create strong connections using minimal pieces.

Chapter 3 starts with the good stuff, motors and gears. What would LEGO Mindstorms be without motors and gears; just a lump of art. In just a few pages the Jin explains everything a first-year mechanical engineering student needs to know about gears. He steps you through creating a gear test bed. This shows you, using a single motor, how all the gears operate and work together. At this point I was wishing I had started reading this book at home near my LEGOS.

I could write in detail about the wonders of each chapter. To keep from writing a review that's the same size as the book, let me summarize some things. This book is filled with lots of examples. Not so much a beginning to end to create a single project, but more a process of creation. Anyone can follow a step-by-step approach for creating a single LEGO project. I have several of those at home sitting on a shelf covered in a thin layer of dust. I call them LEGO art. But with this book, each example evolves you into the next more complex example. The nice thing about these examples is the comments scattered through out. There is a bit of theory explaining how it should work before you get into the construction. This really helps you understand why you are building each part. Eventually you build up to building MIBO, the LEGO doggie on the cover. Personally I couldn't build MIBO since I only have a single RCX, but the concepts he explains gave me new ideas and a drive to build with my current resources.

Every LEGO Mindstorms enthusiast should have this book next to their LEGO storage bin. It's a great reference book when you are in a creative mood.

So I join you out back and we throw a blanket down over the fresh cut grass and grab a couple beers.

    By the end of the second beer, I'm losing track of the conversation and just watching the sweat roll from your neck down to the waistband of your cut offs. You are totally into telling me about the rest of your landscaping plans until you roll up to grab me another beer out of the cooler, and notice that my eyes are on your cutoffs.

    You laugh it off, but I can see the thought of me watching you is making your cock swell. You hand me my beer with a comment about how hot it is. Now, me being me, I can't resist cooling you off and I take a long drag on the beer before leaning over and dragging the beer bottle down the inside of your thigh. You jump so quickly in surprise that you end up dumping half your beer down my chest and now we have both gotten cooled off. This sends us into gales of laughter. But our eyes aren't laughing; your boner is practically crawling out the bottom of your cutoffs and my nipples are so hard they ache.

    Your eyes stay intently on mine as you lean in and pull my hair loose of the pony tail holder making my hair tumble down all over my shoulders and back. You draw a couple strands thru your fingers...and then pull on one of the strands drawing me in for a kiss. My hands come up against your chest for balance, and feeling you all sweaty, I just let 'em slide down to your waistband and around your back. Your lips press gently to mine, and your tongue finds mine and strokes.

    Like a magnet my hair is drawn to your sweaty shoulders and chest, and we're making a whole new kind of heat. You push me down onto the blanket and follow me down. Your kiss is turning harder, more passionate and your hips are rocking with the rhythm of your tongue. You pull on the strings of my bikini top and kiss my neck until my back arches with my moan. You quickly reach under and pull the lower string loose too. Kissing my quickly down my neck, across my shoulders you lick the beer off my chest. Apologizing in a whisper for getting my top wet, you lick the beer off my nipples at the very tips.

    My back arches and I whisper that more than my top is wet. You reward me by sweetly swirling your tongue against the nipples till they are both standing at attention and begging for more. My hips arch and I moan your name. By now I have forgotten where we are but as you lift up to pull my shorts off you notice your neighbor out in his yard with his eyes locked on us (and his hand jacking his lawn hose). You sink back down and kiss me firmly, letting me know exactly how much you want me. Then you whisper that your neighbor is watching, and ask me if we are going to cum inside or out. I laugh gently and whisper that I will cum inside and you can cum wherever you want. Kissing me firmly again you roll slightly to the side and say, "Take a look".

    Peeking over your shoulder I see Mr. Middle America standing dumbly in the middle of his lawn. I quickly pull back and kiss you passionately till you have forgotten that he is there, and are reaching for my shorts again. Unable to resist my playful mood, I scream "Oooooh God, baby, ohh yes make me cum!" and then jump off the blanket and grab my top and run in the house. You curse and start to run after me, catching me just inside the house panting "You're not getting off that easy". "Definitely not, I'm planning on getting off on your very hard, very long cock baby" and I grab you and kiss you with my tongue simulating exactly the stroke and rhythm I want you to make me cum with.

Taking my time, I release you and listen to you moan your appreciation as you lean back against the kitchen counter and drop your head back. Your cut offs sound loud as they hit the floor, but not as loud as your breathing. I slowly engulf your warm sweaty cock in my mouth and listen for the catch in your breathing. Sure enough, your breath halts and then with a whoosh starts back up again, louder and harsher than a moment ago. You widen your stance, giving me plenty of room to lick and suck your cock. My tongue bathes you and I moan my appreciation of your taste. I suck you deep and stroke firmly with my hand at the base, letting my fingers ease under your balls and stroke behind them. I feel your legs tense and you moan loud and reach out and stroke my head and hair and start whispering to me. Over and over you tell me how good it feels, how hot and slick my tongue is, how badly you want me, how beautiful I am, how hard you are.

    With every word I am more aroused, moaning and panting around your cock. My moaning and panting is driving you crazy and you pull me up for another torrid kiss, our lips and tongues mating wildly. You don't bother with my zipper, just running your hand down the inside of my shorts and find my bikini bottoms. Cursing you pull your hand out and reach with both hands for my button and zipper and then push the shorts and bikini bottoms off at once and slide your hand right into my furry mound. You waste no time and sink a finger deeply inside me, never letting go of my mouth and tongue. I moan and melt against you, my mouth going slack, unable to feel anything except your hand. Quickly you insert another finger and at the same time brush my clit with your palm and I shudder and squeeze your fingers with my love muscles.

    I drag my lips up your neck to your ear and pant and whisper in your ear "now, now!" gasping and melting on your fingers. "Oh, no baby" you whisper back and stroke your fingers in and out of me, then spreading my juices over my clit. "My turn to tease you baby" you grin as you take your hand away and pick me up and slide me onto the kitchen counter. "Spread your legs and I'll make you cum" you tell me. Suddenly I feel open and exposed, until I notice that somewhere along the way you unzipped your pants and are slowly jacking your cock. Its rock hard, and all my attention is centered on it. When you lean close and spread my legs, my thighs part like melted butter. I lean back on my hands and let my head drop back until my hair is brushing the counter top. "Ohhhh yes, what a sweet juicy pussy you have baby" you moan. You swirl your tongue along my clit and down into my now sopping slit. The sound of your voice so rough and uncontrolled is like lightning in my soul. You take notice that I tense and shiver when you talk, and immediately start a rolling dialogue pausing only to flick your tongue on my clit. You slide your fingers in circles around my slit, not sliding them in, just around and around.

    "Yes, I'm going to make your sweet pussy cum baby, you know I am. I want to feel this pretty pussy tighten all over my cock baby". I gasp and close my eyes, sinking deeper into the electricity your creating. You suck on my clit and continue to tease my slit until I moan that I can't hold back any longer, "I wanna come on your cock, pleeeeease baby". You immediately slide me off the counter and I wrap my legs around your waist and begin kissing you like tomorrow doesn't exist. You push me against the cold refridgerator door and split me open with your cock. I shudder and immediately begin cumming from the cold on my back and the heat in my slit. My pussy milks your cock hard until you start to cum too. It feels like one very long, very wet cum. I can't tell where mine stops and yours begins. Suddenly there is loud silence as the refridgerator momentarily pauses running. "Lets go to bed" you whisper. "What about the lawn?"

    When I was young I never thought it was needed to go poking for books on how to do more things with my toys. Whatever happened to people thinking for themselves and coming up with their own ideas and ways of using things?

    Something just strikes me as incredibly wrong when you have to use a thick book to play with toys.

    Aren't toys supposed to be an amusing waste of time and not a complete thing you have to study?

  47. Lego in the Lab by iiii · · Score: 1
    Independent of the merits of the parent post here, Legos are used in the lab.

    I recently went to a talk by a guy (Dave Brown of DAU and GMU ) who got his PhD recently, and used Legos in his dissertation experiments. He showed that by "learning" a Bayesian network from actual performance data of a system you could create a model that would predict the performance of the system much more accurately than the textbook formulae it was theoretically supposed to follow.

    To show this he studied battery decay patterns by running lego models around and measuring the speed they went as they ran out of juice. He also uses lego models for prototyping in the classes he teaches at Defense Acquisition University.

    In short, this guy gets to play with legos at his paying job, and for his PhD project. The bastard. I'm so envious. I gotta figure out how to work that into my job.

    Not a literal one but when you are working on your obscure little project, have you ever just hit a dead end, a "you cannot move forward unless..." and after you tear at your hair, run screaming in circles you look to a referance manual and wham there is the solution.

    Books like these speed up the engeneering process a lot. Imagine that if to make a car the wheel had to be reinvented every time, sure we would learn a little more about basic wheel construction than if we just took knowing how a wheel works for granted, but we would never get around to power steering if we were still hung up about how a clutch works.
