Robotic Excavator Builds 6-Meter-High Dry Stone Wall Without Human Assistance ... (10 meters by 1.7 meters by 4 meters) and a permanent retaining wall (65.5 meters by 1.8 meters by 6 meters) ...

A load-bearing wall with a height of 6 meters and a length of 65 meters made using stones and rubble. This was piled up by HEAP, an autonomous excavator developed by researchers at ETH Zurich.

An algorithm running on HEAP's control module subsequently determined the best location for each boulder, in order to build a stable 6-meter (20-ft) high, 65-meter (213-ft) long dry-stone wall.

In brief: Until today, dry stone wall construction has involved vast amounts of manual labour. ... Autonomous excavator constructs a 6-meter-high dry-stone wall. ETH Zurich.
