ACSL's Made-in-Japan drone adopted by Penta-Ocean Construction
for the development of UAV Real Time Receipt Inspection System of Soil VolumeLoaded on Barge using 3D-LiDAR Drone

ACSL's domestic drone “ACSL-PF2” has been adopted to Penta Ocean Vanguard-DroneLiDAR,
a real-time receipt inspection system of soil volume loaded on barge using a drone equippedwith a 3D-LiDAR sensor and an LTE module, developed by Penta-Ocean Construction.

ACSL will continue to develop industrial drones to support people involved in various fields
such as infrastructure inspection, disaster prevention, surveying, and agriculture, which arefacing various challenges such as manpower shortage and operational efficiency.

ACSL Ltd. (Head Office: Edogawa-ku, Tokyo; CEO: Satoshi Washiya; hereinafter “ACSL”) is pleased
to announce that its domestic drone “ACSL-PF2” has been adopted to Penta Ocean VanguardDroneLiDAR” (POV-DL), a real-time receipt inspection system of soil volume loaded on barge using adrone equipped with a 3D-LiDAR sensor and an LTE module(the System), developed by Penta-OceanConstruction Co., Ltd. (Head Office: Bunkyo-ku, Tokyo; President: Takuzo Shimizu; hereinafter“Penta-Ocean Construction”).

In the construction of breakwaters or quay walls, it is necessary to inspect the quantity of stone,
sand, and other materials loaded on each box barge to control the quantity of work. In Penta-OceanConstruction, four to six staff members of the main contractor on a box barge used to inspect thequantity of sand and stone using range rods or flagging tapes, which took about 20 minutes, and forms
1had to be prepared after returning to the office.
When the barge was offshore, the staff members had to travel back and forth by a transportationboat, and in some cases, it took more than an hour to complete the inspection.
ACSL is developing domestically produced industrial drones, which are already being used in various
fields such as infrastructure inspection, logistics, disaster situation monitoring, and security. ACSL
has developed its own flight controllers for controlling drones, and since they are domestically
produced and secure, as well as they can integrate functions with LiDAR and expand functions suchas data uploading via LTE communication, they have been selected by Penta-Ocean Construction todevelop the System.
With the System developed by Penta-Ocean Construction, a POV-DL is flown over the box barge bya land-based staff member, who photographs the loading conditions with an optical camera and uses
3D-LiDAR to measure the loading shape in the hold for 5 seconds, enabling the loading volume to be
calculated and displayed immediately and forms to be generated automatically.
ACSL will continue to develop industrial drones to support people involved in various fields such as
infrastructure inspection, disaster prevention, surveying, and agriculture, which are facing various
challenges such as manpower shortage and operational efficiency and promote their social
implementation.
