Modular robots achieve budding-style physical self-replication
1 reports · 1 sources
Siyuan Zhang and co-authors published a paper reporting budding-style physical replication using isomorphic modular robots: a single module design combines magnetic docking interfaces with two actuated joints, can fold from a planar two-dimensional configuration into a three-dimensional structure, and assembles into two forms, a three-module "trilobite" and a five-module "seal." An operator uses a small number of discrete motion commands to control the already-assembled parent robot, causing it to sequentially magnetically dock with spare modules, assemble a structurally identical second individual, and separate it from the parent; the parent retains all of its original modules. The authors state that this is a preliminary hardware demonstration of the complete process in both forms, and that it currently still relies on direct manual teleoperation rather than autonomous control.

- Robotic Budding: Homogeneous Modular Robots Achieve Physical Self-Replication
Researchers propose a standardized robotic module that combines a magnetic docking interface with two actuated joints and can fold from a flat two-dimensional configuration into three-dimensional structures. Modules of a single design can be assembled into two morphologies: a three-module "trilobite" and a five-module "seal". Using a small set of discrete motion commands, an operator steers an assembled parent robot to dock magnetically in sequence with spare modules, assembling a second, structurally identical individual that then separates from the parent. The parent retains all of its original modules, forming budding-style physical reproduction.
