10. Safety Devices

 The quadrocopter has arangeof safety devices inthetransmitter and ight modelwhichprotectthe

model from damage and/or should reduce possible damage to a minimum. The protection mechanisms are

identiedbyLEDindicators(model)oranacousticwarningsignal(transmitter).

a) Transmitter

The battery condition is continually inspected while the transmitter is in operation. If the voltage level of the batteries

dropsbelowacertainvalue,thetransmitterwillsignalthiswithanintermittentwarningsoundandpermanentashing

ofthe LEDatthetransmitter(gure3,item2).Inthiscase,stopyingatonceandreplacethebatteriesofthe

transmitter.

b) Model

The LEDs in the quadrocopter show if the transmitter is "bound" to the model and reception of the control signal is

proper.ThisisdisplayedbypermanentlylitLEDs(gure5,item5).WhentherearLEDsash,thequadrocopterdoes

not correctly receive the transmitter signal. In this case, "binding" must be performed again.

The quadrocopter constantly monitors the voltage of the connected battery. Should this fall below a critical level over

aparticulartimeframe,thiswillbeindicatedbytheashingLEDs(gure5,item5).

Ifthevoltageundercutispermanentlybelowaspecicvalue,anemergencylandingisinitiatedafterabrieftimeand

the motors are switched off.

 IftheundervoltageisdisplayedatthequadrocopterbyashingofallLEDs,onlyapprox.oneminuteight

time remains to independently return the model to the starting point and land it. If a certain voltage level

oftheightbatteryisreached,thecontrolwillbeswitchedoffbythetransmitterandautomaticlandingis

initiated.Thisprocesscannotbeinuencedbythetransmitteranymore.

If the model is above a body of water, tree, house, street, persons, animals, etc. at the time and/or if the

modelisyingmorethan1.5metresaboveground,themodelmaybedamagedorlostandtheremaybe

property damage and injury to persons/animals nearby.
