Access $SYSTEM_TIMER in Karel

Hi everybody,

I am looking for a way to count the time when the servos of my robot are on. I found the $SYSTEM_TIME[1].SRV_TOT variable that would do the job but I can't access this variable with my Karel program. I am on a R30iB mini plus controler.

Thanks!

Here is my Karel code:

IF Day <> $SYS_TIME.$DAY THEN

IF $SYSTEM_TIME[1].SRV_TOT - Memo_SRV_TIME > 480 THEN

TIMER_DAY[i] = $SYSTEM_TIME[1].SRV_TOT - Memo_SRV_TIME - 480

ELSE

TIMER_DAY[i] = 0

ENDIF

Memo_SRV_TIME= $SYSTEM_TIME[1].SRV_TOT

i=i+1

ELSE

Day = $SYS_TIME.$DAY

ENDIF

And this is the error:

C:\Users\NMARILLE\Documents\My Workcells\Arvis2\loc_timer.kl(45)

45 IF $SYSTEM_TIME[1].SRV_TOT - Memo_SRV_TIME > 480 THEN

^ ERROR

Id must be defined before this use. Id: $SYSTEM_TIME

thanks

Hello HawkME,

I still have the same error, and in my program $SYSTEM_TIME[1].$SRV_TOT is not written in yellow like other system variables.

Do you have an idea?

this is working!

thank you !
