That's going to be the deepest version of a pick and place robot ever. It will be interesting to see how that works...
re: the humanoid robot in that link- I do not see any advantage to going to the trouble of packaging the bot in humanoid form, although having arms articulated in a similar manner to a human would make training operators a lot easier.
Although I have presently have no somewhat intact wreck to use it on, I've been toying with the idea of a similar 3D imaging setup for a wreck site, with stainless or aluminum pipe rails on two sides of the site and a flexible sliding gantry- similar to a CNC router setup- where a 3D camera traverses the wreck site every couple of hours and records every change made to the site. In poor visibility locations, a sonar unit could be used to produce similar results.. Accompanying that would be a GoPro on each corner recording the work day.
