🧠 Algorithm & Sensor Behavior

Track Navigation Logic

How the 14-channel array handles PID line tracking, turns, gaps, and intersections[cite: 1].

STATE: PID Line Following 01 / 08

Straight Line & Gentle Curves

Uses the center 8 sensors for smooth tracking using the PID algorithm with weights (-4, -3, -2, -1, +1, +2, +3, +4)[cite: 1].

Detection: 1 or more of the 8 center sensors detect black[cite: 1].
Action: Adjust motor speeds via PID steering correction[cite: 1].
[ SENSOR ARRAY STATE ]
Weights: -4 to +4 Center Group[cite: 1]
STATE: 45° Turn (Left / Right) 02 / 08

Angled Transitions

Line shifts off-center toward either side but stays within range of the center 8-sensor cluster[cite: 1].

Left Turn: Left Motor Speed ↓ | Right Motor Speed ↑[cite: 1]
Right Turn: Left Motor Speed ↑ | Right Motor Speed ↓[cite: 1]
[ SENSOR ARRAY STATE ]
PID Correction Active[cite: 1]
STATE: Gap Timer Active 03 / 08

Track Gap Handling

When all sensors read white, a 1-second timer triggers to drive straight across the gap[cite: 1].

Found (<1s): Resume PID Line Following[cite: 1].
Lost (>1s): Stop motors completely[cite: 1].
[ SENSOR ARRAY STATE ]
ALL WHITE — GAP TIMER ON (1s)[cite: 1]
STATE: 90° Hard Turn 04 / 08

Sharp 90° Turn Execution

Triggered when outer wing sensor groups detect the line while center sensors lose contact[cite: 1].

Condition: At least 1 of the outer 3 left/right sensors detects black[cite: 1].
Action: Execute a hard differential turn until center aligns[cite: 1].
[ SENSOR ARRAY STATE ]
LEFT WING TRIGGERED → HARD TURN[cite: 1]
STATE: Intersection 05 / 08

Crossroad / Intersection

Detects full cross-lines while maintaining a center reference path[cite: 1].

Condition: ≥3 center sensors AND ≥1 left wing + ≥1 right wing sensor detect black[cite: 1].
Action: Drive straight through[cite: 1].
[ SENSOR ARRAY STATE ]
FULL CROSSOVER DETECTED[cite: 1]
STATE: Diamond Loop 06 / 08

Diamond Split Navigation

Handles track splits where the center path vanishes and splits into two curves[cite: 1].

Condition: Outer left or right sensor detects black with 0 center readings[cite: 1].
Action: Default to Left path selection[cite: 1].
[ SENSOR ARRAY STATE ]
SPLIT DETECTED → SELECT LEFT[cite: 1]
STATE MACHINE TABLE (PART 1) 07 / 08
State Detection Condition Action
PID / Straight 1+ center sensors detect black[cite: 1] 8-center PID (-4 to +4)[cite: 1]
45° / Curve Line offset within 8 center sensors[cite: 1] Continuous center PID[cite: 1]
GAP All sensors white[cite: 1] Start 1s timer, drive straight[cite: 1]
GAP Found/Lost Black within 1s / No black for 1s[cite: 1] Resume PID / Enter LOST state[cite: 1]
STATE MACHINE TABLE (PART 2) 08 / 08
State Detection Condition Action
90° Turn (L/R) ≥1 outer left or right sensor detects black[cite: 1] Execute hard left/right turn[cite: 1]
Intersection ≥3 center + ≥1 left + ≥1 right outer[cite: 1] Drive straight through[cite: 1]
Diamond ≥1 outer sensor active, 0 center sensors[cite: 1] Turn Left[cite: 1]
LOST Gap timer expired (>1s)[cite: 1] Stop motors[cite: 1]
