Special Issue Information

Dear Colleagues,

What is a soft robot? Robotics is the science of building machines that interact with the world around them, move parts of their own, perform tasks that a human might tackle and are programmable, or, in some cases, capable of making certain decisions. The approach to take inspiration from nature and use soft deformable and variable stiffness technologies represents an innovative trend in robotics, which has generated new branches, such as bioinspired robotics and soft robotics, respectively. The importance of soft body parts appears clear in many natural organisms, as animals that are composed almost entirely of soft materials and liquids have increased adaptability and robustness. Grasping and manipulation of unknown objects, locomotion on unstructured and rough terrains, proving safer contact with humans, are just some of the tasks a soft robot is asked to perform.

The integration of functions and the hybrid assembly of soft materials represent key aspects for achieving autonomous soft robots. There is a growing belief that soft materials may help go beyond capacities of current robotics technology. The use of soft materials or deformable structures provides robots with more advanced and efficient abilities, such as squeezing, stretching, climbing, growing, morphing, and others, which were not possible with an approach to robot design based on only rigid links. At the same time, this approach poses challenges to science and technology, which include understanding the ways that robots can adapt their morphologies to the environment, making more difficult control solutions in computational terms, defining new design rules, but also in developing and adopting innovative manufacturing technologies.

Soft robotics is still taking its first steps, but it has already driven promising robotics application scenarios, which include biomedical, service, inspection, search-and-rescue, exploration, opening new perspectives for improving wellness and quality of life.

We invite authors to submit original research and review articles, which stimulate the continuing efforts to understand and improve knowledge in this field.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biomimetics is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) is waived for well-prepared manuscripts submitted to this issue. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We present the basic module of a modular continuum arm (soft compliant manipulator for broad applications (SIMBA)). SIMBA is a robotic arm with a hybrid structure, namely a combination of rigid and soft components, which makes the arm highly versatile, dexterous, and robust. These key features are due to the design of its basic module, which is characterized by a three-dimensional workspace with a constant radius around its rotation axis, large and highly repeatable bending, complete rotation, and passive stiffness. We present an extensive analysis and characterization of the basic module of the SIMBA arm in terms of design, fabrication, kinematic model, stiffness, and bending behavior. All the theoretical models presented were validated with empirical results. Our findings show a positional typical error of less than ≈6% in module diameter (highly repeatable) with a passive stiffness of 0.8 N/mm (≈1 kg load). Our aim is to demonstrate that this kind of robotic element can be exploited as an elementary module of a more complex structure, which can be used in any application requiring high directional stiffness but without the need for an active stiffness mechanism, as is the case in daily activities (e.g., door opening, water pouring, obstacle avoidance, and manipulation tasks).
