Industrial drone maker Percepto raises $45M and integrates with Boston Dynamics’ Spot

Consumer drones have over the years struggled with an image of being no more than expensive and delicate toys. But applications in industrial, military and enterprise scenarios have shown that there is indeed a market for unmanned aerial vehicles, and today, a startup that makes drones for some of those latter purposes is announcing a large round of funding and a partnership that provides a picture of how the drone industry will look in years to come.

Percepto, which makes drones — both the hardware and software — to monitor and analyze industrial sites and other physical work areas largely unattended by people, has raised $45 million in a Series B round of funding.

Alongside this, it is now working with Boston Dynamics and has integrated its Spot robots with Percepto’s Sparrow drones, with the aim being better infrastructure assessments, and potentially more as Spot’s agility improves.

Will the physics add up for near-silent, ion-propelled cargo drones?

Florida’s Undefined Technologies claims it has managed to increase the thrust levels of ion propulsion systems to “unprecedented levels” with its “Air Tantrum” technology, enabling near-silent drones with no moving parts, that look like flying pallets.

All aircraft propulsion systems provide thrust by moving air or another propellant, and for the vast majority of drones that means some kind of fan or propeller spinning angled blades to push air through and create thrust in the opposite direction. Ionic propulsion, on the other hand, is entirely electromagnetic.

The process uses a high-voltage electric field to ionize the nitrogen and oxygen molecules in the air, liberating electrons to create, primarily, a lot of positively-charged nitrogen molecules. These are drawn toward a negatively-charged electrode, usually in the form of a flat screen grid, and as they accelerate, they bang into other air molecules and bump them in the same direction to create an ionic wind.

Drones Solve a Nuclear Waste Mystery at Chernobyl

In 2019, Switzerland-based Flyability had a mystery to solve at the Chernobyl Nuclear Power Plant. Was nuclear waste still present in one of the plant’s decommissioned reactors?

“At the time of the disaster, the fifth block of the Chernobyl Plant was under construction and nearing completion,” a Flyability spokesperson said. “Given the rush to leave, there was no record of whether the holding pools in Reactor Five had ever received the depleted uranium fuel bars for which they had been made.”

Fast forward 33 years – Chernobyl’s decommissioning team needed to know whether any nuclear waste remained in the reactor. Like a flying Sherlock Holmes, Flyability drones took the case.

Hydrogen-powered VTOL drone flies for 3.5 hours

VTOL (vertical take-off and landing) drones are quite versatile, as they combine the vertical flight of a helicopter with the fast and efficient forward flight of a fixed-wing airplane. This one features an extended range, thanks to a fuel cell power system.

The experimental aircraft was developed by a team at the Netherlands’ Delft University of Technology (TU Delft), working with colleagues from the Royal Netherlands Navy and the Netherlands Coastguard. It has a 3-meter wingspan (9.8 ft), weighs 13 kg (29 lb), and features 12 motor/propeller units distributed on its two wings. Even if several of the motors fail, it can reportedly still fly and land successfully.

The drone is also a “tail-sitter”-type VTOL. This means that when taking off and landing, its body is angled upwards, allowing the propellers to work more like a helicopter’s rotor blades. For going into forward flight, the thrust is electronically redistributed between the 12 motors, causing the aircraft to level out into a horizontal orientation.
