A startup south of Austin is using robots to build homes out of clay pulled directly from the ground, reports a local news station:The materials are gathered on site, mixed, and placed on a build plate. From there, a robot lowers from above, picks up the clay with a claw, carries it to the wall and drops it into place. Later, the same robot switches tools, using a hammer attachment to pound the material into shape. "It's kind of trying to replicate how a human might build an adobe house," said software engineer Anastasia Nikoulina... Using machine learning, the system constantly evaluates the wall, adjusting how it builds to create a flat, solid surface... The project is underway at Proto-Town, a ranch between Lockhart and Luling where startups test new technologies, from anti-drone systems to nuclear reactors. The company plans to build their next home on the property, with hopes to do more than 20 homes over the next year.Read more of this story at Slashdot.
