The error message tells you exactly what is wrong.
4. ERROR in C:\robocode\robots\Robot\Noblesse.java (at line 40)
turnRadarRightRadians(Double.POSITIVE_INFINITY);
^^^^^^^^^^^^^^^^^^^^^
The method turnRadarRightRadians(double) is undefined for the type Noblesse
There is no method called "turnRadarRightRadians" that takes a double. There are two ways to fix it:
1) Don't call the (non-existent) method
2) Define the method.
There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
