Fecha de publicación: | 21-may-2020 | Editor: | John Wiley & Sons | Citación: | Computer Graphics Forum 0: 1-14 (2020) | Resumen: | Modelling soft robots is a non-trivial task since their behaviours rely on their morphology, materials and surrounding elements.These robots are very useful to safely interact with their environment and because of their inherent exibility and adaptability skills. However, they are usually very hard to model because of their intrinsic non-linearities. This fact presents a unique challenge in the computer graphics and simulation scopes. Current trends in these elds tend to narrow the gap between virtual and real environments. This work will explain a challenging modelling process for a cable-driven soft robot called Kyma. For this purpose, the real-time Finite Element Method (FEM) is applied using the Simulation Open Framework Architecture. And two methods are implemented and compared to optimize the model efciency: a heuristic one and the Model Order Reduction. Both models are also validated with the real robot using a precise motion tracking system. Moreover, an analysis of robot–object interactions is proposed to test the compliance of the presented soft manipulator. As a result, the real-time FEM emerges as a good solution to accurately and efciently model the presented robot while also allowing to study the interactions with its environment | URI: | http://hdl.handle.net/10261/219259 | DOI: | 10.1111/cgf.14026 | ISSN: | 0167-7055 | E-ISSN: | 1467-8659 |
