Re: Robot Communication Lost for odd reason

Timed loop structures run at an elevated priority to regular code, so it was probably locking out normal operations.

Maybe your catapult loop takes longer than 10 milliseconds to execute? A timed loop runs at a higher priority than normal, and would starve the rest of your program of CPU cycles.
