Error when inputting data using scanner

At one point in my program I use scanner to read the users keyboard input, after pressing enter I get this error:

NullPointerException:

at JerooProgram.makeRobotJeroos(JerooProgram.java:158)

at JerooProgram.main(JerooProgram.java:23)

at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)

at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)

at java.lang.reflect.Method.invoke(Unknown Source)

Right after collecting the data I assign it to a String, I don't know if that matters or not.
