Which drone to use?

Objectives:

• Critically evaluate all types and sizes of

rotary aircraft currently available on the market for their suitability to conduct water quality sampling and monitoring.

• Select

a drone platform for payload adaptation allowing water samples and physico-chemical data collection.

Which drone to use?

Initial Requirements to meet project goals:

• Drone must be able to lift a slung payload of 6 kg.
• Fly for a minimum of 10 minutes
• Fly 200 m carrying this payload weight.
• Capability to fly in wind speeds up to 8 m/s.
• Drone including the payload must not exceed 15kg
• Must be capable of providing “loss of a single motor”

redundancy.

• Must

have GPS + GLONASS capability with redundancy available between them.

• Retractable undercarriage.
• First person view (FPV) integrated zoom camera of at

least 12 MP .

Which drone to use?

• Suitable

for dual

• perators

where the camera movements can be controlled by a second operator with two compatible pilot / camera HD monitors supplying a live view with HDMI output.

• The

primary controller must be able to provide additional channels available for integration with the payload.

• The

controller system must allow for software development kit (SDK) integration.

• The radios must operate on primary EU ISM Band 2.4

GHz transmission with optional 5.8 GHz backup.

• Drone must give real time telemetry information for

the duration of the flight.

• Drone and all its accessories must be CE approved.

Selected Drone

DJI Matrice 600 Pro

Objectives:

• Investigate

various water sampling attachments (payloads) in operation.

• Examine

the applicability

• f

using standardised physico-chemical probes as sensor attachments to the payload.

• Explore the safest means of operating the package
• n site, particularly for take off and Landing modes.
• Consider

communication needs between the

• perator and attached payload.
• Assess the ability of the drone to remotely store and

transmit physio-chemical data.

Prototype Payload Build

Prototype Payload Criteria

Retrieve 2 litres of water from 10 cms below the surface of the lake. Water sample must not be contaminated by the system Collect and log “time stamped” chemical measurements when in the water Final weight suitable for drone transportation Automated payload operation from water entry to exit Waterproof and completely buoyant

Prototype Payload Build

The payload build and design is subject to a non-disclosure agreement (NDA) and is currently deemed to be commercially sensitive

Prototype Payload Build

Key features:

• Prototype payload weight is 6kg outbound and 8kg

inbound.

• A remotely operated camera and “live link” verifies

payload operations.

• Flight time from take off to return is 6 mins, including

sample time in the water of around 3 mins.

• Altitude for flight was maintained at less than 15 m in

all cases.

• Samples were taken more than 100 m from the lake

shore.

Prototype Payload Build

• Collection of a 2 L water sample and in-situ real time

chemical analysis was collected with 100% reliability.

• Operational testing on site verified that Safe “One

person” Take

• ff

and Landing remote from the shoreline can be deployed in difficult locations if required.

• An emergency release has been incorporated and

tested should the payload become fouled or drone performance deteriorate

Limitations encountered during field trials

Limitations UAV with attached water sampling payload Weather Limited by wind speeds greater than 8 m/s Limited by moderate – high rainfall levels Payload Payload weight should be less than 10kg Payload swings in the wind UAV Operational carrying capacity of M 600 drone Personnel Must have experienced, licensed UAV pilot
