this is my response once i run the code with the correct indentations:NameError: name 'tank_drive_on_for_rotations' is not defined on line 48 Here is My code to help with identifying and help correct my issue: #---- sim_magic_preloaded BOILERPLATE ---- from ev3dev2.motor import MoveTank, MoveSteering, SpeedPercent, OUTPUT_B, OUTPUT_C from ev3dev2.sensor import INPUT_1, INPUT_2, INPUT_3, INPUT_4 from ev3dev2.sensor.lego import ColorSensor, GyroSensor, UltrasonicSensor from ev3dev2.sound import Sound from ev3dev2_glue import get_clock speaker = Sound() def say(txt, wait=False, show=True): """Say and optionally show a phrase.""" if show: print(txt) # `wait` controls blocking behaviour speaker.speak(txt, play_type=int(not wait)) tank_turn = MoveSteering(OUTPUT_B, OUTPUT_C) tank_drive = MoveTank(OUTPUT_B, OUTPUT_C) ultrasonic = UltrasonicSensor(INPUT_1) colorLeft = ColorSensor(INPUT_2) colorRight = ColorSensor(INPUT_3) gyro = GyroSensor(INPUT_4) # ----- YOUR CODE BELOW HERE ----- # Initialize robot components tank_drive = MoveTank(OUTPUT_B, OUTPUT_C) ultrasonic = UltrasonicSensor(INPUT_1) colorLeft = ColorSensor(INPUT_2) colorRight = ColorSensor(INPUT_3) gyro = GyroSensor(INPUT_4) speaker = Sound() # Define constants SIDE_LENGTH = 100 # This corresponds to the size of the shape being used in the design.
