The prototype in the linked video was first tested back in 2023, and since then a few startups have set their sights on the technology (e.g. Nomadic Drones and Voltair). When working on the linked prototype we ran into some fundamental iss

In their report ( https://gitlab.com/hybrid-drone/paper ) the authors mention that they implemented one controller for flying and another for diving. The transition seems to be initiated manually, but they propose a few

As far as I can tell from their report ( https://gitlab.com/hybrid-drone/paper ), the authors did not consider underwater RF transmissions in their prototype design and simply use standard COTS components typically used

A more relevant metric than admins/professor would be admin staff/scientific staff. Given that a research group under a professor will probably contain numerous associate professors, assistant professors, postdocs, PhDs, and resea

This is part of our research into drones for power line maintenance that we conduct at the University of Southern Denmark. You may have seen our previous work on drones that can recharge directly from power lines ( https://www.you

The gripper has several modes. There's a mode for charging the battery and providing holding force given AC powerline current, a mode for just holding the drone without charging given AC powerline current (if battery is full), and anot

The voltage of the powerline is not relevant since the charging principle is based on inductive coupling. So as long as you have a current above ~100A the harvester should work, irrespective of voltage. And high currents equal higher chargi

Besides obvious issues such as minor gusts of wind, flight time, and spinning knives around eye level, this is a pretty novel idea. The amount of uses people have found for drones is impressive, e.g. mapping, spray painting, fruit picking,

The world in which the story is set is mostly devoid of living animals. Consequently, owning an animal has become a symbol of wealth and status. Naturally, most individuals cannot afford such a luxury, and a whole industry of robotic animal

The EU could take a page out of Denmark's climate playbook to easily meet emissions targets. A large contributor of projected Danish emissions has been low-lying wetlands converted to farmland via draining. Calculations predicted that
