"In all these cases X is calculated as follows: If the robot’s power supply has more than 100 energy units available, then X = 100; otherwise, X is the amount of power units remaining. Similarly, P is calculated as the smallest of two values: 20 and the actual amount of ammunition units remaining."

You should use this rule only while writing result command, and use default amount of ammunition and energy while calculating.

In my solution there was such bug, that in patrolling mode, after switching to defence mode my program hadn't exited and tried to move or turn.
