| If your line drawing has an intersection, you can tell your robot always turn left or always turn right (for example) by "hard-coding" the Turn Angle. With the program stopped, try setting the Turn Angle to -90 degrees. | If your line drawing has an intersection, you can tell your robot always turn left or always turn right (for example) by "hard-coding" the Turn Angle.
