SMORES
Name	SMORES
Type	Modular robotic system
Developer	Modular Robotics Lab; NASA; University of Pennsylvania
Introduced	2010s
Purpose	Reconfigurable modular robotics research

SMORES is a family of modular self-reconfiguring robotic modules developed for research in swarm robotics, modular manipulators, and autonomous reconfiguration. The system emphasizes connectorized cube-like modules with embedded motors, sensors, and microcontrollers to enable distributed control, locomotion, and collective manipulation. SMORES has been demonstrated in laboratory experiments by academic groups and in collaborative projects with industrial and space research organizations.

Overview

SMORES modules form a reconfigurable robotic platform combining hardware developed by research groups at Carnegie Mellon University, Harvard University, Massachusetts Institute of Technology, University of Pennsylvania, and collaborators at NASA Jet Propulsion Laboratory. The platform was featured in demonstrations alongside projects from MIT Media Lab, Robotics Institute, and research funded by agencies such as the Defense Advanced Research Projects Agency and the National Science Foundation. SMORES contributed to the discourse on modular robotics cited in conferences like IEEE International Conference on Robotics and Automation, Robotics: Science and Systems, and workshops at International Conference on Intelligent Robots and Systems.

Design and Components

Each SMORES module is a cube-like unit housing actuators, power electronics, a battery, and a microcontroller similar to those used in projects at Cornell University and Stanford University. Mechanical interfaces were inspired by connectors used in systems from M-TRAN and PolyBot research groups, and electrical docking resembles approaches from ATRON and SuperBot. Sensor suites include cameras and inertial measurement units comparable to devices used in projects at Georgia Institute of Technology and University of Illinois Urbana–Champaign. Communication layers leverage protocols similar to implementations by teams at ETH Zurich and University of Tokyo for local neighbor discovery and global coordination.

Locomotion and Reconfiguration

SMORES modules achieve locomotion through coordinated actuation and magnetic or mechanical docking mechanisms, drawing on locomotion strategies demonstrated in projects by Klavins Lab and EPFL. Reconfiguration routines borrow principles from decentralized aggregation work at Arizona State University and path-planning techniques used by researchers at Caltech and Johns Hopkins University. Experiments demonstrated crawling, rolling, and chain-based traversal comparable to behaviors reported in literature from IROS and ICRA proceedings. Physical reconfiguration maneuvers were validated against simulation frameworks developed by teams at University of Pennsylvania GRASP Lab and Brown University.

Control Architecture and Algorithms

Control for SMORES combines distributed algorithms influenced by swarm strategies from Santa Fe Institute-associated researchers and formal verification approaches used at Massachusetts Institute of Technology CSAIL. Communication topologies and consensus methods echo studies from Princeton University and University of California, Berkeley laboratories. Motion planning and task allocation used adaptations of multi-agent planning techniques developed at University of Michigan and University of Oxford. Learning-based components, when present, referenced reinforcement learning work from DeepMind collaborators and supervised perception modules comparable to systems in Stanford AI Lab publications.

Applications and Experiments

SMORES was applied to demonstrations of self-assembly, shape morphing, collective manipulation, and environment exploration reported in experiments conducted at Purdue University and University of Washington. Use cases explored included payload transport analogous to projects at ETH Zurich and reconfiguration for confined-space traversal similar to demonstrations by NASA Jet Propulsion Laboratory teams. SMORES modules featured in comparative studies with other modular systems such as M-TRAN, ATRON, and Roombots in workshops at European Robotics Forum and in special sessions at IEEE Robotics and Automation Letters.

Development History and Variants

The SMORES lineage traces to early modular-robotics research from institutions like Carnegie Mellon University and collaborative projects involving NASA research centers and university partners including University of Pennsylvania and Harvard University. Iterations incorporated improvements in docking reliability, battery density, and on-board computation paralleling advances from Apple Inc. and Intel Corporation mobile hardware trends. Variant designs and successor concepts were pursued in parallel by groups at EPFL, University of Tokyo, and industry labs, informing the broader evolution of modular robotics showcased at venues such as IROS and ICRA.
