the completeparts referenceHere’s a detailed overview of all the pieces in your LEGO BOOST kit. You canalso identify LEGO elements precisely by their LEGO ID, which is printed onthe LEGO BOOST test pad.bricksFIGURE S-1 shows the LEGO bricks included in the LEGO BOOST set; their names arelisted in TABLE S-1. For each type of brick, only one color is shown, even when you canfind the part in more than one color in the LEGO BOOST set, as listed in the table. LEGObricks are measured and identified by the number of the studs they have on top. Thesmaller number always comes first, so you say “a 2-by-4 brick,” not “a 4-by-2 brick.” Thewidth of a 1x1 LEGO brick is the Fundamental LEGO Unit, or module (1 module or 1M isabout 8 mm). The LEGO building system is based on this unit, and this consistent unit ofmeasurement will allow you to add your existing LEGO collection to your BOOST robots.1

Technic bricksFIGURE S-3 and TABLE S-3 show the Technic bricks included in the set. The Technicbricks have holes passing through them. Technic bricks are measured by thenumber of their studs. Except for the 1x1 Technic brick (A), there are no Technicbricks with an odd number of studs.ABCDGJEHKLFFIGURE S-3 LEGO TechnicbricksIMTABLE S-3 the Technic bricksLABELNAMECOLORATechnic brick 1x1 with holegreenBTechnic brick 1x2 with holewhiteCTechnic brick 1x2 with cross holeyellow, red, greenDTechnic brick 1x2 with holestanETechnic brick 1x2 with two liftarmsdark greyFTechnic brick 1x4 with wingfrontblackGTechnic brick 1x8whiteHTechnic brick 1x10dark azureITechnic brick 1x16whiteJbrick 1x2 with pindark greyKbrick 2x2 with pin and cross holewhiteLbrick 2x4 with pinsgreyMTechnic frame 4x6dark azurethe complete parts reference3

tilesTiles are like plates without studs. You can use tiles for decorative purposes, tomake flat surfaces, or to build sliding structures (that is, with a brick or a platesliding onto them). Tiles are shown in FIGURE S-7, and their names are listed inTABLE S-7. Tiles have a little groove along their bottom edge to make it easier todetach them. You can use the sharp end of the LEGO element separator as leverto do so (see instructions for using the brick separator on page 6 of the book).ABFCGDHFIGURE S-7 LEGO tilesEIJTABLE S-7 the LEGO tilesLABELNAMECOLORAtile 1x1 roundorangeBtile 1x2orangeCtile 1x3whiteDtile 1x4orangeEtile 1x8whiteFtile 2x2red, blueGtile 2x2 round with holeorangeHtile 2x4yellow, red, blue, green, black, whiteItile 2x2 invertedpinkJpanel 1x2x1dark greydishesFIGURE S-8 shows the dishes; their names are listed in TABLE S-8.

These elements allow you to build in different directions, such as to theside or even upside down. In FIGURE S-9, you can see how this technique wasused in Vernie’s construction.Notice that the sensor is mounted upside down and that the studs of thepart that forms the eye are facing backward. Do you recognize that part? Exactly,that’s the slide shoe you saw above!FIGURE S-9 Vernie featuresa lot of examples of the SNOTbuilding technique.stud directionSNOT partindicator8SUPPLEMENT

The SNOT building technique can make your models look more beautiful,but it can also strengthen assemblies. FIGURE S-10 and TABLE S-9 list the SNOTelements. The brackets are described by their number of vertical studs and horizontal studs.ABCDEFGHFIGURE S-10 SNOTelementsTABLE S-9 the SNOT elementsLABELNAMECOLORAbracket 1x2, 1x2 downorangeBbracket 1x2, 1x2 upredCbracket 1x2, 1x4 downgreyD1x1 brick with headlightyellowEbracket 1x2, 2x2 downwhiteFbracket 1x2, 2x2 upblackGplate 2x2x2/3 with two studs on the sidewhiteHbrick 1x2x2 with studs on the sideredslopes andcurved bricksFIGURE S-11 and TABLE S-10 show slopes and curved bricks. These elementsare mostly used as decorative parts or to replace bricks to get more interestingdesigns. Sometimes, slopes and curved bricks can be used to build small rampsor bevel borders to ease the sliding of objects inside a slot. The slope elementsare named by the angle in their name; for example, slope brick 45 2x2 inverted.The element labeled A is also known as the “cheese slope” because its shaperesembles a slice of cheese.the complete parts reference9

This category includesstraight beams and angular beams (sometimes called liftarms). Beams can haveround holes where you can fit pins, or cross holes where you can insert axles oraxle pins. FIGURE S-12 shows these parts; their names are listed in TABLE S-11.The beams are measured by counting their holes. For example, a straight beamwith three holes is a 3M beam. The number of holes in a beam corresponds tothe length of the beam. As for the bricks, their size is expressed in FundamentalLEGO Units or modules.FIGURE S-12 Beams andliftarms1MABJCDKEFGHILthe complete parts reference11

Some may seem unrelatedto the others, but they all do one basic thing: they connect parts. When buildingwith wood, we use nails, glue, staples, screws, and so on to connect pieces. Inthe wonderful LEGO Technic realm, we use pins, axles and bushes, axle connectors, and the various cross blocks.pins and axle pinsPins hold beams together when fitted inside their round holes. Pins are dividedinto two groups: pins with friction and pins without friction. FIGURE S-13 andTABLE S-12 show pins and 3M pins, axle pins, pins with towballs, and some special 3M pins. This last category is represented by the pin with a stop bush (alsocalled a bushing) and two kinds of long axle pins.12SUPPLEMENT

They are color coded: 2M pins are always grey, while 3Mpins and axle pins are tan. Pins without friction are used mainly to connect moving beams. An axle pin without friction can be used to hold a gear so that it canturn freely. A 3M pin without friction (tan) exists, but it’s not included in the LEGOBOOST set.The pins with friction (D through J) have ridges that increase friction andmake the pin harder to turn. These also prevent connections from rattling. Thepins are color coded to help you identify their function. The 2M pins with frictionare always black, and 3M pins and axle pins with friction are blue. The 3M pinswith stop bushes come in many colors, but they’re light grey in the BOOST set.There are also special 3M axle pins (I and J).the complete parts reference13
