The Lego® Mindstorms® EV3 Laboratory: build, program, and experiment with five wicked cool robots! Dedication about the author about the technical reviewer about the comic designers acknowledgments introduction

playing without a computer whom is this book for? what do I need to use this book? the EV3 software the structure of this book the companion website let’s start already!

comic: the EV3L scientist’s apprentice 1. your LEGO MINDSTORMS EV3 set

the studless way of building

studless vs. studded: the structural differences

naming the pieces

beams

straight beams angular beams frames thin beams and links

connectors

pins and axle pins axles and bushes axle, pin, and angle connectors cross blocks

gears wheels, tires, and treads decorative pieces miscellaneous pieces electronic pieces

the differences between the EV3 retail and education sets conclusion

Comic: continued 2. building ROV3R

base module ROV3R with wheels touch sensor bumper ROV3R with touch sensor bumper line-following module line-following ROV3R front IR sensor ROV3R with front IR sensor wall-following module wall-following ROV3R

alternative: ROV3R with wall-following and line-following modules

Dexter’s cleaning tool ROV3R with cleaning tool

alternative #1: ROV3R with cleaning tool and touch sensor bumper alternative #2: wall-following ROV3R with cleaning tool

ROV3R with treads secret project: grabber module conclusion

Comic continued 3. programming

the building blocks of any program

sequences choices loops

programming with the brick program app your first brick program the block palette

the action blocks

the move block the large motor block the medium motor block the display block the sound block the brick status light block

the wait blocks

the wait touch sensor block the wait reflected light sensor block the wait color sensor block the wait brick buttons block the wait motor rotation block the wait time block the wait infrared sensor block the wait infrared remote block

the loop block conclusion

4. advanced programming with the brick program app

ROV3R with touch sensor bumper making ROV3R drive along geometric paths making ROV3R follow lines

using the brick program to follow lines improving the motion

making ROV3R follow walls

improving the motion

conclusion

Comic continued 5. EV3 programming

EV3 software setup EV3 software overview

the lobby the programming interface the hardware page the tools menu the programming palettes

the action blocks The Flow control blocks the sensor blocks the data operations blocks the advanced blocks My Blocks

project properties

connecting the EV3 brick to your computer importing a brick program

analyzing the imported brick program editing the imported brick program going for precision

traveling a precise distance turning a precise number of degrees

experimenting with action blocks controlling the program flow

the switch block

conclusion

Comic continued 6. experimenting with the EV3 infrared components

remote IR beacon using the remote IR beacon as a remote using sensor blocks and data wires EV3 software features for debugging programs displaying data nicely with the text block understanding data types

data type conversion

following the remote IR beacon using the basic operations of the math block conclusion

Comic continued 7. the math behind the magic!

dealing with measurement noise the math block in advanced mode the round block the compare block

converting numeric values to logic values embedded compare blocks

the constant block improving our wall-following program conclusion

Comic continued 8. LEGO recipes

the angular beams unveiled triangles vs. rectangles extending beams bracing cross blocks gears revisited

getting gears to mesh together well assembling gears gear combinations 90-degree-coupled gears gear trains the worm gear motion transformation

building ideas for the motors

medium motor with front output #1 medium motor with front output #2 medium motor with single lateral output medium motor with double lateral output medium motor with single geared-down lateral output medium motor with gearbox medium motor with multiple outputs large motor with horizontal output large motor gearing options

the logic operations block the timer block conclusion

Comic continued 11. building the SUP3R CAR

main assembly hood assembly main assembly car roof assembly main assembly steering assembly main assembly building the R3MOTE conclusion

Comic continued 12. programming the SUP3R CAR

electronic vs. mechanical differentials using variables using arrays

using the variable block with numeric and logic arrays using the array operations block

using the switch block with multiple cases running parallel sequences (multitasking) building the My Blocks

the ResetSteer My Block the Steer My Block the Drive My Block the ReadRemote2 My Block
