Self-Reconfiguring Robot MorphBot Deep Dive: How 100 Modules Autonomously Transform Shape Based on Tasks

On August 9, 2028, ETH Zurich published a paper in Science Robotics demonstrating the MorphBot self-reconfiguring system composed of 100 robot modules. Each module is a 3-centimeter cubic unit equipped with a processor, communication chip, magnetic docking connector, and drive wheels on all six faces.

MorphBot's core innovation lies in its distributed morphological planning algorithm. When an operator issues a task command (such as "pass through this narrow gap and retrieve the object on the other side"), the system automatically computes the optimal form — 100 modules may first assemble into a snake shape to pass through the gap, then reconfigure into a form with a grasping arm upon reaching the target area.

The paper's first author explained that MorphBot's form switching is driven entirely by local communication between modules. There is no central controller; each module exchanges information only with its six adjacent neighbors, achieving global morphological transformation through "emergence." This architecture gives the system exceptional fault tolerance — even if 10% of modules fail, the remaining modules can still complete reconfiguration.

ETH Zurich plans to collaborate with the Swiss National Robotics Center to apply MorphBot to post-disaster search and rescue and industrial pipeline inspection scenarios. Miniaturizing modules to the centimeter level is the next-phase target.
