Prove it again: Run any move with the gyro off, then on, and compare. The gyro
should win every time — that’s the proof, not a guess.
Watch the heading: Print hub.imu.heading() before and after a turn. Does the
change match the number you typed in turn()?
Re-tune your true 360°: Run robot.turn(360) with the gyro on. Did the heading
land back near 0? Nudge your turn value (355-363) until it does.
Get Ready for Obstacle Avoidance (Next Session)
Today the robot still runs a fixed script — it does the same moves no matter what’s in
front of it. Tomorrow we add the distance sensor so it can react.
Think about a rule like “if something is close, back up and turn.” That “if” is a
decision — exactly how a robot reacts to the world.
Explore More (If Curious)
How far off does a long drive get with the gyro off vs. on? Try a 2-meter straight.
Reset the heading mid-program and see what happens to the next turn.
