Abstract

We demonstrate autonomous construction of structures using a robot arm that can fabricate threads of TPA (Thermoplastic Adhesive) in free space on the fly. TPA has many important material properties that help to greatly simplify the otherwise complex task of building structures in complex environments. We present a model for the formation of TPA strings based on plastic deformation which also includes the temperature dependent material properties which change significantly as the thread is formed and cools. Experiments of drawing TPA show that drawing forces due to the viscosity of the TPA are more dominated by the speed of drawing than the changes in viscosity due to temperature. The load bearing capacity of individual strings is also modelled and measured and structures are built using the TPA strings which due to the adhesiveness can be anchored to a wide range surfaces as well as to other strings. © 2013 IEEE.
