EV3 Coding

The Introductory Coding strand for teams building with LEGO® MINDSTORMS® EV3 and word blocks in the EV3 Classroom app. Work through these in order. Fill each sheet in on screen, then press Download to save a local copy of your answers. It does not turn in your work automatically; give the downloaded file to your teacher. Starting at Project 4, everything you build is tested against a real Stack Attack mission. All seventeen together cover every point on the field.

Phase 1 · Get Connected2 projects

Project 1 Wake Up Your RobotThe brick, charging, Bluetooth, naming your brick, your Robot Card, and running your first program from the EV3 Classroom app.No field missionOpen Project →

Project 2 Your First ProgramHats, stacks, and the block shelf. Timing with wait blocks, lighting the brick display, and five deliberate bugs to find and fix.No field mission Open Project →

Phase 2 · Make It Move4 projects

Project 3 Motors and PortsLettered ports, checking direction with the mirror rule, the wheel-spin trick, and the number the brick is always counting.No field mission — robot on blocksOpen Project →

Project 4 Out and BackTurn tape-measure inches into wheel rotations, drive out of the starting box, stop where a judge can see it, and return fully within the box. Fixing drift with the steering dial.Mission 1 · Mission 10 — base + bonusOpen Project →

Project 5 Learning to TurnOne dial, three turn shapes — radius, one-wheel, and zero radius. Wheel degrees are not robot degrees; build a repeatable 90° turn anyway.Mission 12 — approach only Open Project →

Project 6 Bulldoze RunFour missions and sixteen points using nothing but driving. The OFF definition, pushing technique, and the two kinds of stop.Missions 2 · 4 · 13 · 14Open Project →

Phase 3 · Make It Grab2 projects

Project 7 Your Robot’s ArmA motor that goes to a place instead of just going. The Start Pose Rule, degrees from home, gentle speeds, chosen arrows, and a touch on Botguy.Mission 9 — baseNeeds the arm build Open Project →

Project 8 Arm and Claw TogetherTwo motors as one system — grab, carry, stack, release. Live-judged versus final-position scoring, and the safe starting shape.Missions 12 · 3 · 11 · 13 bonus — 37 ptsNeeds the arm + claw build Open Project →

Phase 4 · Make It Reliable4 projects

Project 9 Names for Your NumbersMake variables, set them at the top, and drop the orange ovals into your blocks. Change a number once instead of everywhere — then stack for twenty points.Mission 5 — base + bonus · 20 ptsOpen Project →

Project 10 Feeling for ThingsThe touch sensor, hexagons, and the checking that never sleeps. Drive until bump, find a wall you can trust, and stack the pyramid.Mission 13 advanced — 13 ptsOpen Project →

Project 11 Counting and Turning by FeelDegrees per inch behind the move block — and the gyro that feels the whole robot turn. Correct the overshoot, and the square finally closes.Missions 9 · 8 · 18 — 40 ptsOpen Project →

Project 12 Teaching Your Robot New MovesMake your own blocks. The shelf, the define hat, and the call — plus inputs, and blocks that call your other blocks.Mission 15 — base + bonus · 18 ptsOpen Project →

Phase 5 · Make It Smart3 projects

Project 13 Deciding What to Doif, if/else, and chains. Asking once versus asking forever — and a claw that notices when it grabbed nothing.Mission 3 advanced — 22 ptsOpen Project →

Project 14 Seeing Light and DarkReflected light answers with a number, and black is the low one. Pick your own threshold, find the line from anywhere, start on a signal.Missions 14 · 18 — 35 ptsOpen Project →

Project 15 Following the LineSteer from a sensor reading. Follow the edge, not the middle, keep the dial under 50 — then reach four of the hardest targets on the field.Missions 6 · 7 · 16 · 17 — 51 ptsOpen Project →

Phase 6 · Clean It Up2 projects

Project 16 Building Your ToolboxOne master Toolbox project every mission starts from. Best blocks in, improvements to the master first, and a backup nobody touches.No field mission — refactorOpen Project →

Project 17 Repeating Without RebuildingThe loop that counts for you. Smooth the arm, repeat the base for the bonus — and collect the last thirty-eight points.Missions 7 · 11 · 16 · 17 — 38 ptsOpen Project →

Strand complete. All 17 EV3-track projects are here. Together they cover every base, bonus, and advanced bonus in the 2026-2027 Game — all 301 points — on LEGO® MINDSTORMS® EV3.
