, Canada, 2G Robotics is a leader in mobile scanning and imaging technologies that improve the speed and accuracy of subsea inspection using remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs) and manned-submersibles.Under Gillham’s leadership, the company pioneered the use of lasers to generate high-density point clouds that help identify small features, defects and collect precision measurements for a variety of survey tasks. 2G Robotics was acquired by Sonardyne Group in early 2020. “Jason has put 2G Robotics on a great course for the future and he leaves behind

This is understood to be by far the highest constant wave ‘pure blue’ power generated from a frequency-doubled fiber laser.“The absorption of

(CP) surveys to help determine the effectiveness of the current cathodic protection systems. A portion of the CP surveys included the cleaning of select anodes throughout the jackets, both by divers and the ROV and the taking of measurements, both manually in the case of the divers and by scaling lasers when taken by the ROV.The surveys of the three jackets took place concurrently, with the diving operation conducted from the jackets and the ROV operations were performed from a floating asset. Through the course of the inspection program, the ROV performed more than 100 dives with nearly 700 hours

Higher Learning & SINTEF’s Existential Rise

for study and one to create commercial value out of the apparent solution. So, when salmon lice infestations at a Norwegian salmon farms became too great a problem, SINTEF adopted a two-tier approach: help regulators study the salmon, the lice and the river and offer to help creating innovations like lasers that shoot the lice off the fish. For large-scale aquaculture and fisheries vessels, there’s SINTEF wave and model analysis in first-class test tanks. The result has been offshore aquaculture structures on the scale of an offshore oil rig and fish-handling vessels for worldwide markets.&ldquo

Crab Comms: "It's not hunger pains, I just want to talk ..."

of stridulation from her ghost crabs, neither their legs nor claws were moving.Collaborating with Damian Elias from UC Berkeley, Taylor verified where she thought the noise could be coming from. The stomachs of many crustaceans contain a gastric mill, a three-pronged structure used to grind food. Using lasers to pinpoint areas of the crab that could be responsible for the noise and then analyzing the sound signature, they found that the interior of the crab where the stomach is located was responsible for producing the sound."The first time I heard the rasp, I couldn't believe how clear the sound

In all, INESC TEC developed the “perception, navigation and awareness systems” for the mining vehicle and EVA robot (together the same EU project).The other AUV developed under the aegis of the EU is the UX-1 (prototype) or UX-1b, a spherical vehicle equipped with lasers to help mining vehicles navigate and mining companies understand the contours of an underwater mine. Impressively, INESC TEC is also a key outfitter for this Europe-wide research success story that involved 17 consortium partners from nine European countries, including robot developers SMD and BMT

Subsea Wreck Brought to Life by Lasers

An innovative underwater survey technique that integrates photogrammetry with Subsea laser LiDAR (SL) technology has helped create accurate, precise, reverse engineered 3D models of a rare and historically significant aircraft resting at the bottom of the sea.The technique was developed during an October 2018 expedition with the nonprofit Air/Sea Heritage Foundation to document the largely intact wreck of a US Navy Douglas TBD-1 Devastator aircraft on the seafloor of the Jaluit Lagoon in the Republic of the Marshall Islands (RMI).Of the 129 Devastators built, all were either lost in battle, destroyed
