Visible in murky water and dark places: Examples of underwater inspections that do not rely solely on diving and the introduction of related products.

Our company prioritizes the safety of workers while conducting inspections and surveys of underwater structures, and we promote the use of underwater robots and drones as a means to achieve stable survey quality, shorten construction periods, and optimize costs. In sites such as bridge substructures, dam embankments, agricultural waterways, and distribution reservoirs, issues of safety and reproducibility often arise in traditional diving surveys due to murky water, dark conditions, and flowing currents. This document is organized around achievements and case studies to help assess "in which environments underwater drones are effective" and "what level of results can be expected" when introducing them to address these challenges. It is not just a product description; it specifically introduces survey methods, verification content, and implementation effects using actual site photos and sonar images. We use the FIFISH W6 MAX and E-MASTER NAVI for inspections, and by combining them with 2D imaging sonar and direct power supply systems, we achieve stable long-duration surveys even in murky water environments. This document can serve as practical reference material for those considering the feasibility of introducing underwater drones or reviewing survey methods.

Utilizing our unique inertial navigation technology, we support both "plane automatic navigation" and "vertical automatic navigation"!

The "FIFISH W6 MAX" is a versatile mission ROV that can be used for offshore wind power, infrastructure inspections, and vessel inspections. With the Q-DVL hovering system equipped in this product, it can lock the drone's position underwater, enabling automatic high-precision stationary holding even in strong currents. This makes operation easier and allows for smooth and precise inspections even in strong flows. 【Features】 ■ Navigation speed of 4.5 knots ■ Maximum diving depth of 350m ■ Equipped with a new industrial motor ■ Improved flow resistance through fluid engineering ■ Payload of 15kg ■ Equipped with AI enhancement, surveying, and autonomous navigation functions *For more details, please download the PDF or feel free to contact us.

Reduce the operator's burden with automatic navigation. Supports high-precision 2D and 3D seabed mapping and measurements using AR laser scalers.

The "FIFISH E-MASTER NAVI" is a compact industrial AI underwater drone developed for measurement, inspection, and investigation in complex underwater work environments. It is equipped with 2D and 3D seabed mapping capabilities and measurement functions using an AR laser scaler, enabling smooth movement and filming underwater through automatic navigation. This reduces the operator's workload while allowing for efficient inspection tasks. Additionally, it features a replaceable dual battery system that supports hot-swapping, allowing for battery replacement without turning off the power. It can also be used in areas where inspections are difficult due to strong water currents or high turbidity. 【Features】 ■ A high-end model focused on time efficiency in operations ■ Smooth filming with a locking function on targets due to advancements in AI system technology ■ New attachments that make it easy to add and remove optional tools ■ Contributes to improved work efficiency with an ultra-wide-angle fisheye lens of 176° (146° underwater) ■ Suitable for underwater inspections of infrastructure and marine facilities *For more details, please refer to the materials.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily visible at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

PERI products are used at construction sites around the world. This time, we would like to introduce the construction work of the "Dunajec Road Bridge" spanning the Dunajec River in the town of Nowy Targ in southern Poland. The road bridge was planned to be constructed using a balanced cantilever method, dividing the cantilever beams starting from each pier into 10 segments. A particular concern was to strictly adhere to the concrete pouring cycle for each segment. To achieve this, a balanced cantilever carriage (VBC) equipped with a hydraulic advance system and an automatic formwork stripping function was adopted. By utilizing the VBC, it became possible to pour concrete for segments up to a maximum length of 5 meters in a single cycle, allowing for efficient and timely construction. PERI products: 1. TRIO Panel Formwork 2. VARIO GT24 Wall Formwork 3. PERI UP Flex Modular Scaffold 4. VST Heavy-Duty Shoring Tower PERI Japan Co., Ltd.
