Payloads
SKYRON2 utilizes a modular payload architecture with interchangeable sensor arms. Swap payloads based on inspection requirements — one platform, multiple testing capabilities.
Short Arm
Lightweight probe for accessible surfaces
The standard payload for routine inspections on accessible surfaces. Its compact form factor minimizes wind resistance and maximizes flight stability, making it ideal for high-volume thickness measurements across large structures.
- Electromagnets
- 2
- Sensor Window
- Single-point
- Surface Prep
- Manual
- Weight Class
- Light
Use Cases
- Routine wall thickness surveys on storage tanks and pressure vessels
- High-volume UT spot checks on accessible hull plating
- Coating thickness verification across flat and curved surfaces
- Rapid screening of corrosion-prone areas on offshore platforms
Long Arm
Extended reach for hard-to-access surfaces
Extends sensor reach beyond the standard envelope, enabling inspections on surfaces obstructed by piping, structural members, or other obstacles. Maintains the same adhesion reliability as the Short Arm while accessing otherwise unreachable measurement points.
- Electromagnets
- 2
- Sensor Window
- Single-point
- Surface Prep
- Manual
- Weight Class
- Light
Use Cases
- Thickness measurements behind piping runs and structural supports
- Inspections on recessed surfaces within confined structural bays
- Measurements on elevated surfaces above catwalks and grating
- Access to areas where the drone body cannot directly approach
Delta Arm
Multi-point scanning from a single attachment
Features a motorized sensor positioner within a 20 cm × 20 cm window. Once attached to a surface, the sensor repositions to take multiple measurements without detaching — dramatically reducing inspection cycle time on dense measurement grids.
- Electromagnets
- 6
- Sensor Window
- 20 cm × 20 cm
- Surface Prep
- Manual
- Weight Class
- Medium
Use Cases
- Dense thickness mapping grids on tank shells and bulkheads
- Critical zone inspections requiring multiple adjacent readings
- Corrosion monitoring programs with closely-spaced measurement points
- Reducing total flight cycles on high-density inspection scopes
SPARM
Integrated surface preparation and measurement
The Surface Prep ARM combines a motorized stainless steel brush with a sensor probe in a single payload. Clears surface rust, loose scale, and debris before positioning the sensor for measurement — eliminating the need for separate surface preparation passes.
- Electromagnets
- 6
- Sensor Window
- Single-point
- Surface Prep
- Motorized brush
- Weight Class
- Medium
Use Cases
- Inspections on weathered or corroded surfaces without prior prep
- Offshore structures where manual surface cleaning is impractical
- Reducing inspection downtime by combining prep and measurement
- Surfaces with loose mill scale, rust, or marine growth
Surface Prep
Dedicated surface clearing for contact-based inspection
A heavy-duty payload engineered exclusively for surface preparation. The motorized wire brush clears rust, loose scale, marine growth, and debris from ferromagnetic surfaces — conditioning them for subsequent UT measurement passes. Designed for workflows where dedicated prep runs are required prior to contact testing.
- Electromagnets

- Brush Type
- Motorized wire brush
- Surface Prep
- Motorized brush
- Weight Class
- Heavy
Use Cases
- Pre-conditioning corroded surfaces before UT thickness surveys
- Removing marine growth and mill scale from hull plating
- Clearing debris from structural members on offshore platforms
- High-volume surface prep across large inspection grids prior to contact testing
Sony Gimbal Camera
Stabilized high-resolution visual inspection
Provides gimbal-stabilized, high-resolution imagery for visual inspection programs. Captures detailed surface condition data for corrosion mapping, coating assessments, and defect documentation across large industrial structures.
- Electromagnets
- N/A
- Sensor Type
- Sony camera
- Stabilization
- 3-axis gimbal
- Weight Class
- Light
Use Cases
- Visual condition assessment of flare stacks, columns, and towers
- Corrosion mapping and coating degradation documentation
- Pre-inspection surveys to identify areas requiring contact testing
- Regulatory visual inspection documentation and reporting
Testing Capabilities
Each testing modality is compatible with specific payload configurations. Most arms support multiple sensor types for maximum flexibility.
UT
Ultrasonic Testing
Contact-based thickness measurement using ultrasonic waves. Detects corrosion, material thinning, and internal defects.
EMAT
Electromagnetic Acoustic Transducer
Non-contact electromagnetic inspection. Ideal for high-temperature surfaces and through-coating measurement without couplant.
DFT
Dry Film Thickness
Coating thickness measurement to verify protective coating integrity across large industrial surfaces.
VT
Visual Testing
High-fidelity visual inspection for surface condition assessment, corrosion mapping, and defect identification.
Pair with the right power system
Heavier payloads like the Delta Arm and SPARM benefit from tethered power for unlimited flight time.
