Snake Robot Slithers Through Pipes, Laser-Welds From Within
What if it was possible to weld pipes from the inside? While not necessary for all welding, sometimes there are metal tubes that need repair, and no good way to get to them other than going inside. For tubes that are too small for humans, repairing them means extensive work getting to them from the outside. What if, instead, we could send robots down the tubes, and have them weld with laser?
