If the robot is sleeping and if human is detected, "wakeup" action is sent.
file services/C_pir.py :
TIMER IS RESET IF HUMAN IS DETECTED

if not RobotIsSleeping:
humanDetected()
IF ROBOT IS SLEEPING WAKUP IS CALLED
if RobotIsSleeping:
sleepModeWakeUp()
file inmoovLife/sleepMode.py
SLEEP ACTION IS CALLED BY A X SECONDS TIMER
def SleepTimerRoutine(timedata):
if pirTimerStarted and not RobotIsSleeping:
sleepModeSleep()
