![]() ![]() Manipulation tasks in unstructured environments are still challenging for roboticists both in grasping of unknown objects and arm displacement or positioning. The experimental results pointed out that our design and approach can lead to the realization of robots able to act in unknown and unstructured environments in synergy with humans, for a variety of applications where compliancy is fundamental, preserving robustness and safety. The SIMBA manipulator has demonstrated excellent grasping and manipulation capabilities by being able to grasp objects with different fragility, geometry, and size and by lifting objects with up to 2 kg of weight it demonstrate also to be robust and reliable. We used a hybrid approach in designing and manufacturing by integrating soft and hard components, in both materials and actuation, providing high lateral stiffness in the arm through flat springs, soft joints in fingers for more compliancy and tendon-motor actuation mechanism providing flexibility but at the same time precision and speed. In our novel design, we have proposed (1) a modular continuum arm with independent actuation units for each module, to increase maintainability (2) a soft reconfigurable hand, for a better adaptation of the fingers to objects of different shapes and size (3) a moving base for increasing the workspace. In this paper, we describe the conceptual design and implementation of the Soft Compliant Manipulator for Broad Applications (SIMBA) manipulator, which is designed and developed for participating in the RoboSoft Grand Challenge 2016. 2The BioRobotics Institute, Scuola Superiore Sant’Anna, Pontedera, Italy.1Center for Micro-BioRobotics, Istituto Italiano di Tecnologia, Pontedera, Italy.Emanuela Del Dottore 1,2 Ali Sadeghi 1 Alessio Mondini 1 Barbara Mazzolai 1 ![]()
