Background

Robotic joints are indispensable components that directly determine the capabilities and performance of diverse robotic systems. In the domain of collaborative and assistive robots, adaptive joints are essential for enabling safe human-robot interaction, demanding compliance and adaptability to ever-changing environments. Current approaches employ soft actuators, variable stiffness mechanisms, and compliant transmission elements to enhance safety and operational efficiency. On the other hand, industrial robots necessitate joint designs that prioritize high precision, repeatability, and robustness. The intricate design of these joints balances compactness, reliability, and a broad spectrum of functional prerequisites, necessitating a multidisciplinary synthesis of expertise in mechanics, actuation systems, control algorithms, and materials science to deploy joints that not only function precisely but also adapt effectively to the specific demands of different robotic tasks.



Research Topic aims to explore the latest advancements in the design, modeling, control, and validation of robotic joints, addressing the increasing complexity of modern robotics. As robotic systems evolve, there is an increasing need for innovative joint designs that can meet the diverse and challenging functional requirements across applications ranging from human-robot collaboration to industrial automation. We invite contributions that cover the full spectrum of robotic joint development challenges, including the mechatronic design and modeling of cutting-edge compliant, soft, and high-precision joints suitable for dynamic environments. Critical focus areas include advanced control strategies to enhance joint safety and efficiency, emphasizing the real-time adaptation of stiffness characteristics tailored to specific tasks, or the compensation of transmission errors via sensor-based or model-based methodologies. Papers exploring virtual prototyping, simulation, and testing techniques are also encouraged to deepen the understanding of joint behavior under diverse conditions. Additionally, we welcome experimental studies that validate innovative designs and methodologies, including case studies demonstrating the practical applications of robotic joints in industries such as healthcare and manufacturing.

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.
