Need help with Mars Rover.

Hello, My rover is supposed to explore the entire field independently and circle the hills in the process. The area to be explored is with border hills. My problem is that when the rover hits the boundary hill when it comes back from the right side it turns left even though the code says it should turn right. The code of the rover is right below. I hope you can help me.
?

Change all string comparisons from: var == "string" to "string".equals(var)

Unfortunately, your suggestion didn't bring anything. He still turns left instead of right on the left side. Still, many thanks to you.

You need to move line 3 up outside the act method (line 0 or -1). You have it where it is always a new var assigned with "links". It ?may? also be required that it should be assigned "rechts", instead.
