An interesting thought, im pretty wary on most automated construction techniques, but dry stone construction does seem like a good fit for automation. It needs to be done before any other construction is really done and takes a decent chunk of time even for a team of humans so not a lot of people or other things going on around the area or in the way. There are still some issues that need experimentation. You can go 99% of the way with fairly simple imaging, but that last 1% can be tricky and usually requires tactile sensation and probing and pushing on stones to get a rock solid fit, but perhaps the actual technique/style of stone fitting would alleviate that last bit.
