# Station Maintenance

## Check station is positioned on flat, leveled, and elevated surface

Confirm that the entirety of the station is placed on a flat, level and dry **OUTDOOR** working area off the ground for best internal operational movements and precision landing of the drone. An Industrial leveler can be used as a tool to verify the positioning. Confirm that there is no overhead obstructions such as tree branches or other structures.

## Interior visual inspection

Visually inspect the physical condition of the station from the interior. Monitor any abnormalities inside the station such as unknown damages, stains, or debris as well as watermarks or any deformation of the silver-coated insulation inside the station. Carefully clean the station interior section if necessary. Be sure to use caution when dealing with sensitive electronic components and do NOT use water inside the station. The cooling fan also should be cleaned frequently to maintain proper temperature and ventilation.

## Landing pad

The landing pad should be cleaned periodically. The precision landing QR codes along with the AR- tag should be in good form to allow the Precision Landing process to run smoothly. Inspect the health of the QR stickers routinely.&#x20;

Confirm that the internal pad Aruco marker is in good condition without any damage to the design of the tag. Clean with a moist towel but do not leave any wet puddles on the pad.

## **Check power supply connection**

Make sure the power cable connection and socket at both ends (station-power source) are intact and perfectly secured to avoid short circuits due to weather exposure during operation. Clean the male and female conductor point with contact cleaner if necessary and confirm that the prongs are in good condition without damage or debris.

## Check ethernet connectivity

Ethernet LAN connection is one of the most important things for this Hextronics stationed Drone operation. Making sure the functionality of this connection is mandatory to allow data transfer processes to run smoothly. Inspect male and female connection points frequently.

## Inspect cooler compartment and ventilation.

Make sure there is no obstruction in the HVAC compartment. Clean the ventilator section thoroughly using a cleaning brush or anti-static cloth. Verify that the fan is blowing cold air. Open the service panel to access the Micro AC component inside the case and use compressed air to remove any debris.

Carefully place your hand over the internal fan and confirm that the fan is blowing air, and cold air when the cooler is enabled. Confirm that the fan is spinning and producing sufficient air flow when powered on. The fan works independently from the compressor so you can also verify that the air being blown from the fan is cold to verify the compressor system.

## Check the state of wiring and components

Reference the wiring orientation according to the wiring diagram. Look for visibly damaged points and make sure no cable is loose or hanging. Please contact the Hextronics Support team if you detect any defective wiring. The below listed components should be securely fixed and connected within the station. Please see the component diagram to reference individual parts.

Drone R&#x43;**,** Raspberry Pi, Odroid N2 Flight CPU, Battery chargers, Battery PCBs, Cooling Fan, Ethernet LAN switch Box, 24V Power Supply Box, Hexboard, PTC Resistive Heater Climate Control Relays, Compressor Control PCB, Evaporator AC Coil.

## Inspect antenna

Check the physical the omni-directional antennas. Make sure both antennas are in good condition and the underside connections are securely tightened. Clean the connection point if necessary using the contact cleaner and remove the antenna during any relocating process.

## Check battery charger slots

Examine each battery charging slot carefully. There should be no debris or obstruction inside the charging docks as it has been shaped precisely according to the drone battery dimension. Perform visual inspection of the charging slots and clean the area if necessary, using a vacuum, contact cleaner or anti-static cloth.

Individually confirm that each battery slot tray is in good condition with no damage, and that the internal charging connector is straight and not missing any pins and that the pin housing is not bent or deformed in any way. Also confirm that batteries are inserted smoothly into the slots during battery swap operations.

## Inspect mechanical parts to operate with no obstruction

The mechanical moving parts must be individually inspected to confirm there are no obstructions and that the components move smoothly. Clean and grease the area if necessary by referencing the maintenance module timeline to prevent metal-on-metal wear & damage.

## Weather resistance seals

The weather seals are responsible for maintaining a dry interior of the station, any moisture or humidity within the station is likely to result in electrical & hardware malfunctions. Please confirm that the weather seals are in good condition and cover the entirety of the designated area.

## Belt condition & tension on Landing Pad and Gantry

Proper belt tension is required for hardware operation movements to be successful. Manually inspect and squeeze each belt loop for any damages or missing teeth. The belts should be rigid and tight, loose belts should be addressed as soon as possible for proper station operations to continue.

Confirm that the belt teeth are orientated in towards the pulleys and on track, also inspect the integrity of the teeth to confirm there are no bald spots or missing teeth.
