Notice the world
A sensor sees the line. A player sees a warning, a door, a character, or an impossible signal.
OPEN WORKBENCH / EXPERIMENTS WELCOME
Make a system
show its work.
I like the moment a black box starts making sense. This is a little corner for tracing inputs, adjusting rules, and finding out what the system does next.

01THE LINE-FOLLOWING SANDBOX
A TINY CONTROL LOOP YOU CAN TOUCH
Tune the response.
Watch it find the line.
My FLL team used PID-based line following on a LEGO Mindstorms EV3 robot. This browser demo is an illustrative sandbox, not telemetry or a recovered copy of that robot’s settings.
SIMULATION / OPEN LOOPREADY TO ROLL
The pale line is the track. The mint trace is the robot’s path. Try increasing P, then add a little D to calm the response.
CONTROL DECK
Change the gains
TRACKING ERROR—LAP 01 / 00%
Adjust the gains, then start the run.
02WHAT THIS LITTLE EXPERIMENT IS FOR
A robot and a game
share a loop.
The objects are different. The satisfying part is familiar: send something into a system, get a response, and learn from the gap between what you expected and what happened.
Choose a response
The controller corrects. The game applies its rules. The designer decides what information to give you.
Feel the result
The robot finds the track again. The world changes. Then there’s a new reason to try.
03THREE THINGS ON THE BENCH
Different materials.
Same curiosity.
EV3 line follower
Team robotics: robot design, lead programming, and the delight of getting a real machine around a real course.
Read the competition storyCOTé:PTC
A science-fiction concept where imperfect control, quiet, mission markers, and memory are part of the storytelling.
Explore the projectThis little corner
A static site, a few interactions, and a chance to see what can live on a tiny hosting setup.
