This paper presents the building of lightweight tensile structures with quadrocopters. The construction elements (such as ropes, cables, and wires) in this kind of structure are subject to tension forces. This paper identifies the basic building elements (nodes, links) required for the construction of tensile structures, and translates them into meaningful trajectories for quadrocopters. The use of a library of building elements is suggested. Hybrid force-position control strategies based on admittance control are exploited. Prototypical tensile structures are built by quadrocopters to validate the proposed approach. An accompanying video shows the building process.
In its more common manifestations, granular jamming relies on vacuums and membranes to bring about liquid‐to‐solid phase change in materials. Petrus Aejmelaeus‐Lindström, Ammar Mirjan, Fabio Gramazio and Matthias Kohler of ETH Zurich, and Schendy Kernizan, Björn Sparrman, Jared Laucks and Skylar Tibbits of the Massachusetts Institute of Technology (MIT), describe two projects as members of the two research groups at ETH and MIT that have been collaborating to examine the possibilities of jamming in architecture and construction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
