A research project at Harvard aims to demonstrate an autonomous multi-robot systems capable of the construction of 3D structures. The hardware comprises a mobile robot and specialized passive blocks; the robot is able to manipulate blocks to build desired structures, and can maneuver on these structures as well as in unstructured environments. To illustrate the robot’s ability to perform complex tasks combining these functions, they demonstrate it autonomously building a ten-block structure significantly larger than itself.
