“…The scope and practicability of outer-space missions could be greatly enhanced through utilizing on-orbit robotics and assembly, whereby, outer-space exploration hardware could be reused for a lower cost. Studies such as [55] have shown that the assembly and performance efficiency may be kept roughly constant while incorporating infinitely scalable reconfigurability by employing modular materials, e.g. reversibly assembled cellular composites.…”

Despite their contributions to the financial efficiency and environmental sustainability of industrial processes, robotic assembly and disassembly have been understudied in the existing literature. This is in contradiction to their importance in realizing the Fourth Industrial Revolution. More specifically, although most of the literature has extensively discussed how to optimally assemble or disassemble given products, the role of other factors has been overlooked. For example, the types of robots involved in implementing the sequence plans, which should ideally be taken into account throughout the whole chain consisting of design, assembly, disassembly and reassembly. Isolating the foregoing operations from the rest of the components of the relevant ecosystems may lead to erroneous inferences toward both the necessity and efficiency of the underlying procedures. In this paper we try to alleviate these shortcomings by comprehensively investigating the state-of-the-art in robotic assembly and disassembly. We consider and review various aspects of manufacturing and remanufacturing frameworks while particularly focusing on their desirability for supporting a circular economy.

“…A second step has been the design of simple autonomous robots [54,56] that are able to move on the resulting lattice structures and move their elementary cell components, thereby allowing the reconfiguration of the overall edifice. Combining such materials and robots in space promises to greatly increase the dimensions of constructible facilities and spacecraft, as well as offering to extend mission capabilities with reconfiguration and re-use [47]. Because moving mass and volume into space remains a critical factor, it is conceivable that the involved robots (just like the building material) can be produced and assembled in space; because robots will still require more complex production steps than the passive material, their availability will remain a bottleneck, so limiting their number is highly desirable.…”

We provide algorithmic methods for connected reconfiguration of lattice-based cellular structures by finite-state robots, motivated by large-scale constructions in space. We present algorithms that are able to detect and reconfigure arbitrary polyominoes, while also preserving connectivity of a structure during reconfiguration; we also provide mathematical proofs and performance guarantees. Specific results include methods for determining a bounding box, scaling a given arrangement, and adapting more general algorithms for transforming polyominoes.
