Its maiden voyage will come in May 2014, in the Yellow Sea. "The mission will be excavation of ancient artifacts by cooperating with marine archaeologists," said lead researcher Bong Huan Jun.<br />"CR200 will do precise seafloor mapping of the turbid area with acoustic equipment. We will also try a number of possibilities of CR200's role for underwater excavation."

"I expect there will be demands in scientific fields if Crabster does well in its sea trials," said Huan Jun. "Then many other Crabster will be possibly manufactured for use across the world."
