Karel Searches for the Doors

Now, Karel finds himself in a world as shown below on the left. He starts in the SW corner $($facing east$)$ and wants to get to the SE corner and pick up his item there $($see the end position below$).$ However, there are a number of walls blocking his way. Fortunately for Karel, each wall has a single one$-$tile$-$wide opening. And even more fortunate is that he already knows how to move through an opening for a single wall, as you told him how to do that in the previous problem. Now he just has to do it repeatedly. And remember to pick up the item.
