The "Electromagnetic Wave Exploration Drone" is a survey robot that can conduct investigations without being affected by the field environment. Since no prior preparation is required, it is possible to conduct surveys in less than half the time of conventional methods. Additionally, by utilizing the developed AI automatic analysis software, the speed of analysis and the accuracy of detecting cavities have significantly improved. 【Product Lineup】 ■ Drone Rear: A model capable of conducting cavity investigations under bridges using contact methods. ■ Drone Slope: A model equipped with non-contact radar. ■ Drone Vertical: A model that adheres to walls for conducting surveys. *For more details, please refer to the PDF materials or feel free to contact us.

The "U3V SYSTEM" is a 3D radar exploration system equipped with a multi-channel radar at the rear, capable of conducting measurements while traveling at high speeds. Compared to conventional radars, the amount of information acquired per run has significantly increased, greatly improving analysis accuracy and efficiency. It can be utilized for various applications, including subsurface cavity exploration, buried pipe investigation, bridge deck deterioration surveys, asphalt thickness and concrete pavement thickness surveys, and other buried object investigations. 【Features】 ■ Multi-channel system allows for area measurements across multiple survey lines at once ■ Continuous high-speed exploration eliminates the need for traffic regulation ■ Utilizes 3D radar recordings for multi-type analysis and evaluation ■ Ensures reliable acquisition of surrounding situation images linked to deformation locations *For more details, please refer to the PDF document or feel free to contact us.

"MIMM-R" is a mobile high-speed 3D tunnel inspection system that acquires color images of tunnel linings and high-precision three-dimensional spatial position data while in operation. By equipping a non-contact radar, it has become possible to investigate the thickness of concrete linings and detect voids behind them. The reduction in on-site workdays, decrease in high-altitude work, and less traffic congestion due to the absence of traffic regulations significantly enhance safety at the site. Additionally, as traffic regulations are not required, it contributes to the reduction of CO2 emissions caused by traffic congestion, ultimately benefiting the environment. 【Features】 ■ No need for traffic regulations ■ Significant increase in survey quantity due to the absence of traffic regulations ■ Measurements can be taken at speeds of up to 70 km/h by measuring with the antenna separated from the wall *For more details, please refer to the PDF document or feel free to contact us.

The "Road Tunnel Disaster Prevention Vehicle (Tunnel Master)" is a vehicle that can diagnose the integrity of tunnels in multiple ways. It is capable of a wide variety of diagnostics and investigations, ranging from "driving diagnostics" such as non-contact electromagnetic wave backfill surveys and 3D shape measurements to "detailed diagnostics" such as contact-type electromagnetic wave backfill surveys. It can improve on-site efficiency and safety, and is expected to be active in both preventive maintenance and post-maintenance. 【Features】 ■ In-vehicle operation: Remote control of antennas while driving ■ Lifting and rotating mechanism: Lifting from 2.7m to 3.8m (up to 4.5m), with 180° rotation left and right ■ High-altitude work platform: Equipped with four outriggers to enhance stability during high-altitude work ■ Roof carrier: Work can be performed on top of the cabin ■ Interchangeable: Automatic impact measurement is possible by replacing the antennas of the beam-type measurement system *For more details, please refer to the PDF document or feel free to contact us.

The "Wall-Mounted Automatic Tracking Waterway Tunnel Inspection Device" is an unmanned survey and diagnostic system equipped with a wall automatic tracking mechanism that ensures the high-sensitivity camera always faces the wall, capturing continuous images of the wall surface. As a primary functional diagnostic survey, it naturally flows through a non-pressurized waterway tunnel while water is flowing, capturing continuous images of the arch section of the waterway wall. These images are recorded and stored as digital unfolded images, allowing for the assessment of deformation and other conditions. 【Features】 ■ Cable-free, natural flow type ■ Compact and lightweight ■ Easy to transport and carry (entry/exit size 75×75 cm, weight 35 kg) ■ Stable image capture, capable of extracting deformation and understanding underground conditions ■ Diagnosis with accuracy equal to or greater than "visual inspection during water stoppage" *For more details, please download the PDF or feel free to contact us.
