In late 2019, after years of learning aviation and aerospace engineering, Hector (Haofeng) Xu determined to study to fly helicopters. On the time, he was pursuing his PhD in MIT’s Division of Aeronautics and Astronautics, so he was acquainted with the dangers related to flying small plane. However one thing about being within the cockpit gave Xu a larger appreciation of these dangers. After a few nerve-wracking experiences, he was impressed to make helicopter flight safer.
In 2021, he based the autonomous helicopter firm Rotor Applied sciences, Inc.
It seems Xu’s near-misses weren’t all that distinctive. Though massive, business passenger planes are extraordinarily secure, individuals die yearly in small, personal plane within the U.S. A lot of these fatalities happen throughout helicopter flights for actions like crop dusting, preventing fires, and medical evacuations.
Rotor is retrofitting present helicopters with a set of sensors and software program to take away the pilot from a number of the most harmful flights and broaden use circumstances for aviation extra broadly.
“Folks don’t understand pilots are risking their lives on daily basis within the U.S.,” Xu defined. “Pilots fly into wires, get disoriented in inclement climate, or in any other case lose management, and virtually all of those accidents could be prevented with automation. We’re beginning by focusing on probably the most harmful missions.”
Rotor’s autonomous machines are in a position to fly quicker and longer and carry heavier payloads than battery powered drones, and by working with a dependable helicopter mannequin that has been round for many years, the corporate has been in a position to commercialize rapidly. Rotor’s autonomous plane are already taking to the skies round its Nashua, New Hampshire, headquarters for demo flights, and clients will be capable of buy them later this yr.
“Quite a lot of different corporations try to construct new automobiles with a number of new applied sciences round issues like supplies and energy trains,” stated Ben Frank ’14, Rotor’s chief business officer. “They’re attempting to do every thing. We’re actually centered on autonomy. That’s what we specialise in and what we predict will convey the most important step-change to make vertical flight a lot safer and extra accessible.”
Constructing a crew at MIT
As an undergraduate at Cambridge College, Xu participated within the Cambridge-MIT Change Program (CME). His yr at MIT apparently went nicely — after graduating Cambridge, he spent the following eight years on the Institute, first as a PhD scholar, then a postdoc, and eventually as a analysis affiliate in MIT’s Division of Aeronautics and Astronautics (AeroAstro), a place he nonetheless holds at the moment. In the course of the CME program and his postdoc, Xu was suggested by Professor Steven Barrett, who’s now the top of AeroAstro. Xu stated Barrett has performed an necessary position in guiding him all through his profession.
“Rotor’s expertise didn’t spin out of MIT’s labs, however MIT actually formed my imaginative and prescient for expertise and the way forward for aviation,” Xu stated.
Study from Agility Robotics, Amazon, Disney, Teradyne and lots of extra.
Xu’s first rent was Rotor Chief Expertise Officer Yiou He SM ’14, PhD ’20, whom Xu labored with throughout his PhD. The choice was an indication of issues to return: The variety of MIT associates on the 50-person firm is now within the double digits.
“The core tech crew early on was a bunch of MIT PhDs, and so they’re a number of the finest engineers I’ve ever labored with,” Xu stated. “They’re simply actually good and through grad faculty they’d constructed some actually improbable issues at MIT. That’s most likely probably the most crucial issue to our success.”
To assist get Rotor off the bottom, Xu labored with the MIT Enterprise Mentoring Service (VMS), MIT’s Industrial Liaison Program (ILP), and the Nationwide Science Basis’s New England Innovation Corps (I-Corps) program on campus.
A key early choice was to work with a well known plane from the Robinson Helicopter Firm quite than constructing an plane from scratch. Robinson already requires its helicopters to be overhauled after about 2,000 hours of flight time, and that’s when Rotor jumps in.
The core of Rotor’s answer is what’s often known as a “fly by wire” system — a set of computer systems and motors that work together with the helicopter’s flight management options. Rotor additionally equips the helicopters with a set of superior communication instruments and sensors, a lot of which have been tailored from the autonomous automobile business.

“We consider in a long-term future the place there are now not pilots within the cockpit, so we’re constructing for this distant pilot paradigm,” Xu stated. “It means we now have to construct sturdy autonomous techniques on board, but it surely additionally signifies that we have to construct communication techniques between the plane and the bottom.”
Rotor is ready to leverage Robinson’s present provide chain, and potential clients are snug with an plane they’ve labored with earlier than — even when nobody is sitting within the pilot seat. As soon as Rotor’s helicopters are within the air, the startup affords 24/7 monitoring of flights with a cloud-based human supervision system the corporate calls Cloudpilot. The corporate is beginning with flights in distant areas to keep away from threat of human harm.
“We’ve got a really cautious method to automation, however we additionally retain a extremely expert human professional within the loop,” Xu stated. “We get one of the best of the autonomous techniques, that are very dependable, and one of the best of people, who’re actually nice at decision-making and coping with surprising eventualities.”
Autonomous helicopters take off
Utilizing small plane to do issues like struggle fires and ship cargo to offshore websites just isn’t solely harmful, it’s additionally inefficient. There are restrictions on how lengthy pilots can fly, and so they can’t fly throughout hostile climate or at evening.
Most autonomous choices at the moment are restricted by small batteries and restricted payload capacities. Rotor’s plane, named the R550X, can carry masses as much as 1,212 kilos, journey greater than 120 miles per hour, and be geared up with auxiliary gasoline tanks to remain within the air for hours at a time.
Some potential clients are thinking about utilizing the plane to increase flying occasions and enhance security, however others need to use the machines for totally new sorts of purposes.
“It’s a new plane that may do issues that different plane couldn’t — or possibly even when technically they might, they wouldn’t do with a pilot,” Xu stated. “You may additionally consider new scientific missions enabled by this. I hope to go away it to individuals’s creativeness to determine what they’ll do with this new instrument.”
Rotor plans to promote a small handful of plane this yr and scale manufacturing to supply 50 to 100 plane a yr from there.
In the meantime, within the for much longer time period, Xu hopes Rotor will play a job in getting him again into helicopters and, finally, transporting people.
“At the moment, our impression has so much to do with security, and we’re fixing a number of the challenges which have stumped helicopter operators for many years,” Xu stated. “However I feel our greatest future impression can be altering our each day lives. I’m excited to be flying in safer, extra autonomous, and extra inexpensive vertical take-off and-landing plane, and I hope Rotor can be an necessary a part of enabling that.”
