VR robot in a maze - from Blocks to Python

Recently I produced a post about playing with Vex Robotics VexCode VR blocks and the Maze Playground.

The post finished with me saying I would like to play with Python and do a Python version of it. Well it is actually very easy to do it.

You can do it in two stages from the block code. First click on the <> icon (lighted in the figure above and it gives a further view producing Python code that changes as you change the blocks. The last stage is to convert to a text project (button at the bottom right of the screen.

Example of the code.

myVariable = 0

def when_started1():

global myVariable

drivetrain.drive_for(FORWARD, 100, MM)

while not down_eye.detect(RED):

drivetrain.drive_for(FORWARD, 5, MM)

if right_bumper.pressed():

drivetrain.drive_for(REVERSE, 30, MM)

drivetrain.turn_for(LEFT, 20, DEGREES)

drivetrain.drive_for(FORWARD, 20, MM)

else:

if left_bumper.pressed():

drivetrain.drive_for(REVERSE, 30, MM)

drivetrain.turn_for(LEFT, 120, DEGREES)

drivetrain.drive_for(FORWARD, 10, MM)

else:

drivetrain.turn_for(RIGHT, 10, DEGREES)

drivetrain.drive_for(FORWARD, 10, MM)

wait(5, MSEC)

vr_thread(when_started1())

The code in action

This is possibly a nice transition tool going from block-based programming to text-based.
