Driving straight using gyroscope (Lego Dance)
Introduction
We create a simple code with gyroscope to drive a straight line. Sometimes starting the gyroscope fails and it starts drifting. Fix it by unplugging and plugging the cable.
Theory
The plan:
Robot drives a straight line perpendicular to its starting position. If the robot for some reason goes to different direction, the gyroscope will fix the direction. However, the final position might be different.
The code:
We use loop (orange) with gyroscope (yellow) block, math add block (red) and steering (green) block. This is called as a proportional control system, P-controller.
Exercises
- Drive a longer distance.
- Add small obstacles, eg a mat or small LEGO building on the driveway to disturb the robot.
- What is the meaning of b in math block? Try with different values.
- Drive a square by creating similar Drive Straight code blocks one by one. Use gyro reset in between.
