2G Robotics has offered a variety of customized solutions for underwater scanning. These solutions rarely come ready off the shelf and the creation of custom frames and rigging is a necessity.
To collect proper data, it is important that ULS scanners remain stationary relative to the target surface throughout the entirety of a scan. Consistency is key to accurate results. They have used different methods to ensure that the laser scanners are capable of delivering accurate data. Recently they have developed a potting process that allowed the use of electromagnets for quick and easy deployment of custom scanner frames. With proper insulation, electromagnets are capable of successful operation in water.
The company has developed a potting process for complete insulation of electromagnets making them a viable for underwater use. This process allows the magnets to function at considerable depth. A wide range of underwater electromagnet strengths are available and full customization makes this solution possible for many applications.
2G Robotics’ most recent deployment integrated a grid of eight electromagnets, remotely controlled through an ROV. Spring loaded, these underwater electromagnets were capable of articulating to fit different diameters of steel platform members. They were designed to hold a custom 2G frame in place for the completion of scans, maintaining stability. 2G robotics has designed and deployed custom frames for use with divers as well as different sizes of remotely operated vehicles. Underwater electromagnets are capable of stabilizing micro class vehicles, allowing these smaller units to successfully deploy the laser technology. Units from Videoray or Seabotics, for example, would be capable of such an operation.
Underwater electromagnets are very useful because they can be turned on or off by interrupting the circuit. Before energizing the underwater electromagnet, the magnets are easily placed into position by ROV or diver. With the introduction of this technology to the industry underwater deployment specifically related to stability of small systems underwater has been dramatically improved.
