CERBERUS Robot

Remote Internal Blade Inspections

As a pioneering leader in the internal inspection movement, CERBERUS was originally designed in 2018 and has undergone continuous improvements to remain at the cutting edge of the industry. It is a compact crawler robot designed for the remote inspection of wind turbine blade interiors. It navigates complex internal geometries to capture high-definition footage, eliminating the safety risks and inspection limitations associated with human confined space entry.

Equipped with a frontal 360º panoramic camera and dual high-resolution lateral cameras, CERBERUS captures every internal detail under a smart, auto-adjusting LED lighting system. Sensor-driven odometry provides precise location tracking during inspections.

The data collected during internal inspections allows for a comprehensive evaluation of the blade's structural integrity, analyzing the adhesive joints of the leading edge, as well as the web-to-shell and spar-to-shell bonds. Additionally, it facilitates detailed panel inspections to detect potential cracks, layup delaminations, core crushing in sandwich panels, or faults in the lightning protection system (LPS).

FAQ´s

How deep into the blade can inspections be performed?

With compact dimensions of 240 x 540 x 200 mm, CERBERUS is engineered to navigate deep into the internal cavities of wind turbine blades. The robot can advance through internal structures until the physical taper of the blade prevents further movement, ensuring the maximum possible inspection coverage allowed by the blade´s geometry and internal conditions.

How is confined space access minimized during inspections?

To carry out the inspection, the operator only needs to enter the confined space of the blade to place the robot at the root.

Are there safety measures to prevent the robot from becoming stuck inside the blade?

Yes. Every crawler is supported by a high-strength integrated safety cable, ensuring the robot can be securely retrieved from any point within the blade cavity.

What is the process for turbine operation during the inspection?

Yes. Every crawler is supported by a high-strength integrated safety cable, ensuring the robot can be securely retrieved from any point within the blade cavity.

During the internal blade inspection procedure, the turbine is stopped, and the blade to be inspected is placed horizontally parallel to the ground.
