Dear Colleagues,

Autonomous robots have special energy needs, their batteries need to be recharged after every use and their autonomy is limited, particularly for aerial vehicles (UAV). In urban and grid-connected systems the recharging procedure is controlled with very well-known approaches; however, in remote and countryside areas, when the grid connection is not warranted or even non-existent, those robots have to do their duty regardless. Therefore, a special energy supply has to be developed to recharge operational robots and the concept of “off-grid” has a particular and special relevance in such cases.

Considering this fact, in this Special Issue, new research and developments are expected regarding efficient energy supply systems based on renewable sources in tough environments where no grid connection exists.

In this Special Issue, potential topics include, but are not limited to the following:

• Renewable energy supply systems for mobile robots.
• Energy processing for mobile robots: New trends in conversion architectures.
• Energy management in mobile robots: New trends in control algorithms.
• Energy optimization in robotic applications.
• Optimal battery recharging systems in off-grid environments.
• New trends in electrical vehicles (EV) recharging in off-grid environments.
• Contactless battery charging in mobile robots.
• Rethinking usual robotic applications with off-grid supply.
• New robotic applications in off-grid recharging systems.

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 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. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). 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.
