Robotic leading edge repair
Complete leading edge repairs with robotic consistency.
SPARROW combines heavy-lift drone deployment, precision tooling, controlled material handling, and repair documentation to execute repeatable leading edge protection work onshore and offshore.
What SPARROW is
A repair robot delivered directly to the blade.
SPARROW is Clobotics’ drone-delivered robotic system for wind turbine blade leading-edge repair. A heavy-lift drone positions the robot on a horizontal blade, where modular tooling prepares the damaged surface and applies the specified leading-edge protection system.
The controlled workflow reduces dependence on manual work at height, helps repair teams use narrow weather windows more effectively and keeps the preparation, application, quality review and process record connected around the same blade.
Drone-delivered robotics
Built around the full repair environment.
SPARROW combines stable drone deployment, modular repair tooling and operator oversight in one field-ready system for onshore and offshore campaigns.
- Heavy-lift drone deployment
- Modular surface-preparation tooling
- Controlled LEP application
- Traceable process records
How it works
A controlled repair sequence—from deployment to verification.
The workflow keeps the robot, tooling, operators and process data connected through every repair step.
Position the blade
The blade is placed horizontally with its leading edge facing upward.
Place the robot
A heavy-lift drone lowers SPARROW smoothly onto the repair area.
Prepare the surface
Modular tooling sands and cleans the damaged leading-edge zone.
Apply protection
SPARROW applies the specified leading-edge protection system.
Record the work
The team checks quality and retains a traceable repair record.
SPARROW in action
Watch the repair system move from field setup to work on the blade.
See the drone-delivered robot, the supporting equipment and the operating team come together in a controlled repair workflow.
Evidence, not only hardware
Show the repair and the record behind it.
The strongest proof is a connected story: the robot in operation, the field team controlling the process and the data retained after the repair.
Repeatable tooling and controlled application reduce variation between blades.
Experienced crews supervise deployment, tooling and quality checks.
Process data supports verification and future maintenance planning.
Offshore proof
Commercial offshore campaign partner Robotic repair moved from prototype to commercial operation.
SPARROW has completed record-setting offshore leading-edge repair campaigns with Ørsted, demonstrating how a drone-delivered robot can use weather windows more effectively while keeping technicians away from the blade surface.
FAQ
Questions operators ask about SPARROW.
What type of repair does SPARROW perform?
SPARROW is designed for wind turbine blade leading-edge preparation and leading-edge protection application using modular repair tooling.
How is SPARROW placed on the blade?
A heavy-lift drone lowers the repair robot onto a horizontally positioned blade, allowing deployment without a rope-access repair team on the blade.
Can SPARROW work offshore?
Yes. The system has completed commercial offshore robotic repair campaigns and is designed for both offshore and onshore operation.
How is repair quality documented?
The workflow records process steps and operating context so the completed work can be reviewed and retained with the blade’s maintenance history.
