EMS spokesperson Robert Mulaudzi said they were going back on site on Friday.
“This time we will also be deploying robots, thanks to Delta Scan, a company that deals with robots in most of the engineering sector,” he said.
The robots will help them to clear up any uncertainty in some of the lines which have lots of methane gas and electrical cables.
“So we will be using these robots to make sure that we can be able to locate Khayalethu. If we do see something along the line we will be able to immediately send our rescue technicians to recover the boy while the cleaning process in the split chamber is continuing,” he said.
