New to coding
- Block Lab, Worlds 1 to 3: sequences, loops, variables.
- Quest Lab: rebuild two favourite missions in real Scratch.
- Editor: make something of your own and save it.
Code and robotics
Build programs that do something
Block Lab · scratch.logicnaut.dev
Learn logic with Scratch style blocks
Seven worlds and 46 missions, from “walk to the star” to FizzBuzz, factorial, and a five point star. Blocks use the real Scratch names and colours, Jarvis acts out every program, and the checker explains exactly what happened.
- Sequences, loops, variables, decisions, repeat until, words
- Run animates each block; Check tests several inputs
- Works on a phone or tablet, tap to add blocks
Quest Lab · quest.logicnaut.dev
The same missions inside real Scratch
The full Scratch editor with a quest panel beside it. Build the mission with every block Scratch has, press Check, and the real Scratch engine runs it and grades what the sprite actually did.
- Real editor, real engine, real .sb3 files
- Same goals, hints, and par as Block Lab
- Best on a tablet or laptop
Editor · editor.logicnaut.dev
A free style Scratch editor for your own ideas
Nothing to pass, nothing checked. Make a game, a story, or an animation. The project saves on this device every few seconds and can be saved as a file that opens on scratch.mit.edu.
- Every Scratch block, sprite library, and sound
- Autosave on the device, no account
- Start here after a Block Lab world to make something yours
PID Lab · pid.logicnaut.dev
PID control for VEX IQ robots
A simulated BaseBot whose motors are not twins, so it drifts. Read the gyro, find the error, and steer it back: first with an if, then P, I, and D. Every mission is checked on several robots and has an “In VEXcode IQ” card.
- Six units, 20 missions, from open loop drift to a PID square lap
- Encoder degrees, gyro heading, and the slipping wheel that fools encoders
- Field view, rotation chart, and an IQ Brain screen
PI Lab · pi.logicnaut.dev · private, password
See your own robot code think
One real VEXcode IQ program, a P drive and a PI turn, built up in fourteen small levels: the gyro number, error, P, the error bucket, loop speed, and the stop window. The last levels run the learner's own blocks on a simulated robot.
- Guess first, then run, then two quick checks per level
- Step one block or one loop trip at a time, with live values
- Load a newer .iqblocks file; it never leaves the device
Logicnaut CS · cs.logicnaut.dev
C++ through guided missions and a real compiler
32 guided C++ missions across ten sectors, with prediction puzzles, bug fixes, and code completion. A Practice Lab compiles real C++20 in an isolated sandbox when a signed in learner presses Run.
- Three routes: Young Explorer, Independent Learner, Fast Track
- Optional guardian account for cross device progress
- Sequential unlocking, XP, and review suggestions
Math and the world
Know the numbers and the map
Logicnaut Math · math.logicnaut.dev
An accelerated Grade 7 journey, one idea at a time
Nine units, 21 modules, and 110 skill destinations, with original playable missions on ratios, rates, proportions, percents, and simple interest. Each day: warm up, see it, try it, teach it back.
- Word decoders, visual examples, and friendly retries
- A teach back step that checks for the core idea words
- XP, levels, Starbits, and a reward shop
Foundations · foundations.logicnaut.dev
Deeper mental models for elementary math
Sixteen visual game quests for a learner who can already calculate and needs to see why: multiplication and division meaning, US money, time, and geometry. Wrong answers reveal free strategy clues.
- Four worlds, open from the start
- Models you can see, like the 64 chair array
- A Spark for every completed quest
MapSprint USA · usa.logicnaut.dev
Every state, every capital, on a blank map
Find the state, spell its name, spell its capital. Seven stages from warm up to a mixed test, with region filters, pinch zoom for the small states, and a voice that says and spells each word.
- Points, accuracy, streak, and a personal best per drill
- A missed spelling is retyped before the round moves on
- Hands free rounds that advance on their own
Where to start
Three flight paths
Robotics team
- PID Lab, Unit 1: see the drift and why hand tuning fails.
- Units 2 and 3: proportional steering, then encoder degrees.
- Units 4 to 6: I, D, and full PID, then run it on the BaseBot.
Math and beyond
- Foundations for the why behind multiplication and division.
- Logicnaut Math for the accelerated Grade 7 map.
- Logicnaut CS when the next language should be C++.
The Logicnaut promise
Private by design. Progress lives in the browser on the device. Children never get accounts, email, or ads. The only cloud account is an optional guardian account in Logicnaut CS.
Encouraging by default. Hints are free, stars only go up, and there are no rankings, loot boxes, or streak loss. A wrong answer is a “not yet”, with a reason.
Honest checking. Every lab runs the work and reports what happened, in plain words a nine year old can act on.
Built to transfer. Block names match Scratch, robot blocks match VEXcode IQ, and the C++ is real C++.
