The engineers in the Ai have to wait out coastal Virginia's rainy spell to begin flight training and the suspense is KILLING us, so in the meantime, let's talk about why the Hive is the coolest thing to enter Building 1222 since
First and foremost, the Hive is a research vehicle– which means that efficiency and reliability are paramount. No one cares how fast our UAV will go if it can't get through a full day of flight tests. So, its creator Zak built in triple-redundant GPS and ESC systems to make sure that no matter what happens, the Hive stays in the air. It even powers up prop-by-prop instead of all at once to get maximum mileage out of every battery charge.

The co-ax props aren't just a design element; they're engineered to produce enough lift to carry a medium-sized dog (in theory!). When the vehicle itself is already six feet wide, that's an unprecedented amount of power for an Ai research vehicle.
"[The Hive] can carry a sixty-five pound payload with ease," said Zak. "It's got a lot of thrust."
 |
| Stacking the props also has aesthetic advantages for when multiple vehicles take to the sky. According to Zak, "You don't wanna have four octos out there with eight arms each. It looks ridiculous." |
Despite its might, the Hive was designed to be portable. Once it folds up into a 20x20 inch square (sans battery pack), it becomes compact enough to fit in a military-issue Pelican backpack. Expanding and shrinking the vehicle is easy– just remove the screws, fold the arms into position, and replace the screws.

So: it's packable, it's efficient, it's enormous. All good qualities in an Ai robot. But the most innovative thing about the Hive, the reason we're so excited to include it in our atmospheric science mission, is what it can do once we get it three identical friends.
This is a twenty percent scale model of the module that will link four Hives together into what we're calling a "Mothership." We can use this to link them together on the ground and take them off together as a single mega-UAV, but with a flick of a switch, this piece will un-link the vehicles mid-flight, deploy a controllable parachute, and drift back to the ground.

"The NASA meatball alone is two and a half feet in diameter [on the full-size product], so that gives you some size perspective," Zak said. "And look at all the space inside. There's room for all kinds of sensors in there." The inside of the central element is so roomy that he sees potential for making the piece fully autonomous, capable of deploying its own parachute and steering itself to Earth.
Overall, what makes the Hive such a sensational development for our lab is the limits it removes from our research. Even beyond atmospheric science, The Hive has the power and versatility to do anything we need it to do, indoors or outside.
"This really is a multi-use platform," Zak said. "You can use it in any of the projects here at Langley."
