Robotic Excavators and Diggers in Construction Automation; 2024 Guide

Building is a hard profession, and there is a persistent labor scarcity in Europe to construct the houses, schools, and highways that we depend on daily. So why not assign the laborious task to construction robots we won’t have to?

That is precisely the goal of the study being done by experts at the Robotic Systems Lab at ETH Zurich in Switzerland. Without human assistance, they have trained an autonomous excavator to build stone walls out of rocks weighing several tons. The machine’s initial task was building a loading bearing wall that was 65 meters long and six meters high. If used at a larger scale, the method might open the door for quicker, greener buildings.

Robotic excavators and diggers make a 3D map of the construction site and locate the wall’s stones and building blocks on their own using LiDAR sensors. The excavator can detect and seize big stones in its immediate surroundings thanks to specially made equipment and machine vision, which is a computer vision system. It is also capable of registering their center of gravity and approximate weight.

Robotic excavators and diggers then use an algorithm to identify the optimal placement for every stone, placing each piece with an accuracy of less than one centimeter in the intended spot. In a single consignment, the autonomous machine can lay 20 to 30 stones, roughly the amount that might be supplied by a single delivery.
