Brad Wallace May 24, 2015 Waterloo startup explores HMS Erebus Brad Wallace May 24, 2015 But not so much in the water. More on the computer.I wonder if we can get a copy of the model? That would be soooo cool! Mr. Gillham, 33, founded 2G Robotics in 2007 as an engineering student at the University of Waterloo. The tech firm manufactures cutting-edge underwater laser scanners used by Parks Canada to preserve archaeological records from Erebus. These lasers use an “advanced version of trigonometry” to calibrate multiple points by scanning the surface of the wreck over and over again, creating a 3-D model of the site, said Mr. Gillham.Parks Canada can then use these incredibly detailed models to study the geometry of the wreck, or virtually “dive” the wreck site sitting at headquarters in Ottawa.
