Special Issue Information

Dear Colleagues,

Climbing robotics has steadily gained interest over the years due to its potential of unlocking safe, efficient, and autonomous inspection and maintenance of dangerous and hard-to-reach spaces. Robots targeting these tasks have been traditionally multidimensional in terms of utilized adhesion and motion technologies, while being tailored to match specific application scenarios and environments. The motion and adhesion capabilities required for efficient handling of sensors and tools and the structural requirements posed by different environments spanning from aerospace to nuclear and underwater facilities have led to several actuation methods developed and evaluated on climbing robot designs. The challenges faced during autonomous operation of such systems, as well as the need for higher efficiency and safety, have in turn led to new advances in localization and navigation methods for collaborative and modular climbing machines.

In this Special Issue, both theoretical and practical contributions are encouraged, covering all aspects related to the design, modeling and control of adhesion and locomotion actuators for climbing robots, as well as contributions in navigation, localization, and collaboration of climbing robot systems. Comprehensive surveys on current technologies, industries and applications related to climbing robotics are also encouraged.

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 submissions that pass pre-check are 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. Actuators is an international peer-reviewed open access monthly journal published by MDPI.

The electroadhesion pad is mainly studied for applications, such as climbing robots and grippers. In this paper, we present our study with the confirmation of the adhesion properties of the electroadhesion pad with a double-insulating layer, pad modeling, and optimal design. Modeling and analysis consider the air layer generated during the manufacturing of both conventional single-insulated structures and dual-insulated structures. Through the finite element analysis simulation, the characteristics of the electroadhesion were verified, and modeling verification was performed, based on the variables that had a large influence as follows: applied voltage, electrode area, dielectric thickness, and permittivity. The electrode is made of aluminum, the substrate is made of silicon, and the dielectric is made of polyimide film. An error of up to 8.3% was found between the modeling and simulation. The optimization results were validated based on a pad applied to a climbing robot measuring 320×480mm² and weighing 2.8 kg. As a result, the optimal pad design resulted in an error of 7.3% between the modeling and simulation. Full article
