Help Karel the robot clean up her world!

Commands

Tell your robot how to complete this level by writing commands. Commands go in the Robot tab inside the commands method

void commands() {
  // put your robot instructions here!!!

}

Here's a list of the commands you can use.

move()

Move the robot forward one square in her current direction.

A wall must not be directly in front of the robot when moving.

turnLeft()

Turn the robot left 90 degrees.

pickBeeper()

Tell the robot to pick up a beeper from the world.

A beeper must exist at the robot's current position.

putBeeper()

Tell the robot to put down a beeper at her current position.

The robot must have beepers in her beeper bag.

turnOff()

Stop running commands and print the results.

Errors

If you break the rules of a command, your robot will shut itself down. For example, this set of commands:

void commands() {
  move();
  move();
  move();
}

will cause your robot to shutdown because it may not walk through walls. Here is what that will look like in the world:

and in the console:

Press space to start
Karel is facing East  at [1, 1] with 0 beepers.
Karel is facing East  at [2, 1] with 0 beepers.
Karel is facing East  at [3, 1] with 0 beepers.
Karel !!!Error!!! Tried to walk through a wall!

Goal

This is what it should look like when you have successfully completed the level.
