So check this out, researchers from ETH Zurich just went and did some crazy stuff. They used an autonomous excavator to build a massive 6-meter-high and 65-meter-long dry-stone wall. And get this, the whole thing is part of a digitally planned and autonomously excavated landscape and park. How nuts is that?
The team did all this as part of the National Centre of Competence in Research for Digital Fabrication (NCCR dfab). They used sensors on the excavator to map out the construction site and find all the building blocks and stones needed for the wall. And get this, the excavator’s got specially designed tools and machine vision approaches to scan and grab those large stones, and even figure out how much they weigh and where their center of gravity is.
Then, this algorithm comes in and figures out the best spot for each stone, and the excavator just goes ahead and places them all in the right spot, all on its own. This thing can place like 20 to 30 stones in one shot – that’s about as many as one delivery could provide. How wild is that?
