Line Follower v2
A PID-tuned line follower that laps our track in 9.8 seconds.
The problem
Our first robot oscillated on curves and lost the line at speed.
What we built
Moved to an 8-sensor IR array, wrote a PID loop with feed-forward on curves and cut 140 g from the chassis.
Hardware
ATmega328P, TB6612FNG motor driver, N20 600 RPM motors, QTR-8RC sensor array, 2S LiPo.
Software
Arduino C++, PID tuned with a serial plotter and logged runs.
Outcomes
Lap time went from 16.4 s to 9.8 s. Placed 2nd at the zonal robotics meet.
