SENSYN ROBOTICS, Inc. has released a new version of its drone-based power transmission facility inspection application "POWER GRID Check" with the addition of a large power transmission facility inspection function.
The inspection of large transmission facilities (such as extra-high-voltage transmission lines and multi-circuit facilities) can now be handled, further expanding the scope of inspections. In addition, functions developed in response to user requests have been implemented.
The inspection technology for large transmission facilities (such as extra-high-voltage transmission lines and multi-circuit facilities) is based on technology researched and developed jointly with Chubu Electric Power Grid Co.,Inc..

Support for Automatic Inspection Flights of Large Transmission Facilities (e.g., Extra-High Voltage Transmission Lines and Multi-Line Facilities)
The previous version of "POWER GRID Check" was applicable only to standard transmission facilities (load system transmission lines, etc.), but the new version enables automatic inspection flights for large transmission facilities (extra-high voltage transmission lines, multi-circuit facilities, etc.).
There were three major issues to overcome in order to perform automatic inspection of large transmission facilities.
(1) Large power transmission facilities have wide legs, so the object to be photographed cannot fit within the angle of view.
(2) Insulators are longer than standard insulators (e.g., load transmission lines), so the insulators do not fit in the angle of view.
(3) For safety reasons, it is necessary to maintain a greater separation between the insulators and the charging section than standard transmission facilities (load system transmission lines, etc.).
With this version upgrade, we have implemented an algorithm to solve the above issues and have been able to support large transmission facilities (e.g., extra-high-voltage transmission lines and multi-circuit facilities).
In addition, in response to numerous requests from users, we have implemented a function that automates tasks that previously required manual registration, thereby streamlining the work time.
Implementation of Data Management Function
Utilizing the data management function "Datastore" of SENSYN CORE, a business automation platform owned by SENSYN ROBOTICS, a data management function specialized for "POWER GRID Check" was implemented.
Since a drone acquires a huge amount of images, it takes a long time to sort through all the images of facilities taken by the drone, and there was a risk that data management of inspection history would become complicated. By implementing the data management function specialized for "POWER GRID Check," we were able to realize trend management by accumulating data, such as automatically sorting images according to the equipment part. In the future, we plan to implement an abnormality extraction function to further improve the efficiency and sophistication of data management.
Features of POWER GRID Check
- Automatic inspection of steel towers and power lines in a batch
Inspection of steel towers (supports and girders) and power transmission lines (overhead ground lines and power lines) can be completed with a single application.
- Can be operated with commonly available drones
Since general-purpose drones and cameras that are generally available on the market are used instead of special sensors, flexible operation is possible without depending on the manufacturer or model of the drone.
- Data management function
Acquired data can be centrally managed in the cloud. Repair plans can be shortened by reducing the number of man-hours required for physical delivery and eliminating the need for posting to reports.
In the future, we plan to add an automatic tracking function for power transmission lines (overhead ground lines and power lines). In addition, ongoing research and development will be conducted to further reduce labor and automate power transmission facility inspections through drone control using AI, image analysis, and other advanced technologies.
About SENSYN ROBOTICS
Our mission is to evolve what is considered “commonplace” in society with the power of robotics. It is under this mission that we have continued to take on pressing challenges in regards to specific social issues in various fields focused on facility inspections, disaster response, and security and surveillance by achieving the full automation of work with the power of robotics since our establishment in October 2015.
