Tiny Robobee X-Wing powers its flight with light

We’ve seen Harvard’s Robobee flying robot evolve for years: After first study to fly, it learned to swim in 2015, then to jump out of the sea again in 2017 — and now it has another trick up its non-existent sleeve. The Robobee X-Wing can fly employing merely the power it collects from light hitting its solar cell, establishing it possible to stay in the air indefinitely.

Achieving flight at this scale is extremely hard. You might think that being small-scale, it would be easy to take off and maintain flight, like an insect does. But self-powered flight actually gets much harder the smaller, which sets insects among the most bafflingly marvelous accomplishments of engineering “weve had” encountered in nature.

Oh, it’s easy enough to fly when you have a wire feeding you electricity to strength a pair of tiny wings — and that’s how the Robobee and others flied before. It’s only very recently that researchers have accomplished meaningful flight using on-board power or, in one case, a laser zapping an attached solar panel.

robobee chartThe brand-new Robobee X-Wing( identified for its 4-wing architecture) achieves a brand-new milestone with the ability to fly with no battery and no laser — simply plain full-spectrum light coming from above. Brighter than sunlight, to be fair — but close to real-world conditions.

The team at Harvard’s Microrobotics Laboratory fulfilled this by making the strength changeover and wing mechanical structures improbably lightweight — the whole thing weighs approximately one quarter of a gram, or about half a paper clip. Its power consumption is likewise lilliputian 😛 TAGEND

Consuming merely 110-120 milliwatts of power, the system matches the thrust efficiency of similarly sized bugs such as bees. This insect-scale aerial vehicle is the lightest thus far to achieve sustained untethered flight( as opposed to impulsive jumping or liftoff ).

That last bit is some shade thrown at its challengers, which by nature can’t quite achieve” sustained untethered flight ,” though what constitutes that isn’t exactly clear. After all, this Dutch fluttering flyer can go a kilometer on battery power. If that isn’t sustained, I don’t know what is.

In the video of the Robobee you can see that when it is activated, it kills up like a bottle rocket. One thing they don’t really have space for on the robot’s little form( yet) is sophisticated flight control electronics and strength storage that could let it use merely the vigor it needs, flapping in place.

That’s probably the next step for the team, and it’s a non-trivial one: adding weight and new systems entirely changes the device’s flight profile. But give them a few months or a year and this thing will be hovering like a real dragonfly.

The Robobee X-Wing is exhaustively was reflected in a paper published in the periodical Nature.
