Beschreibung

Recent advances in the rapidly growing field of soft robotics have shown that robots made from soft materials surpass traditional rigid-link and continuum robots in performance in terms of adaptability and flexibility. Owing to their structure-inherent compliance, soft robots are also credited with being able to bridge the gap between humans and autonomous machines. However, for soft robots to become mass-producible in future days, rapid design and modeling tools are indispensable. Currently, the need for fast and versatile development tools is contradicted by a design flow that is mainly driven by experiments. To counter the perceived gap between experimentally and simulation driven research in soft robotics, we have developed a finite element based kinematic modeling framework for soft continuum robots that is applicable to a range of different designs. The corresponding design and modeling tool effectively combines the capabilities of both MATLAB and Abaqus via a Python interface. In this paper, we provide detailed description of the developed methodology and demonstrate the feasibility of the approach on a soft pneumatic actuator.
