Reliable Robotics Emerges From Stealth with Autonomous Passenger Airplanes

Are you ready to jump on an airplane without a pilot onboard? San Francisco-based Reliable Robotics thinks that you are. They have emerged from stealth and are demonstrating their autonomous, small craft, passenger airplanes flying over populated areas.

The company is led by SpaceX and Tesla veterans and emerges from stealth with $33.5 million in venture capital funding to transform the future of aviation. While we're all busy watching autonomous mobile robots get deployed in stores, warehouses and hospitals, Reliable has been testing its autonomous passenger planes in the air.

What Is An Autonomous Passenger Airplane?

In the first flight, the pilot pressed a button on a remote user interface and the unmanned four passenger Cessna 172 Skyhawk (C172) automatically taxied, took off, and landed. Most recently, the company demonstrated fully automated remote landing of an even larger aircraft, the Cessna 208 Caravan (C208), capable of carrying 14 passengers.

“Automated aircraft are going to fundamentally shift the entire airline business, and Reliable Robotics is well positioned to be a key player in this new market. The progress their team has demonstrated in a short amount of time is very impressive,” said David Neeleman, Founder of five commercial airlines including JetBlue Airways.

Reliable Robotics seamlessly integrated its autonomous platform onto the 2,550 pound C172. They began the C172 program in January 2018 and completed fully automated gate-to-gate operation before the end of that year. Extensive system safety analysis and testing was conducted prior to the unmanned test flight in September 2019. This marked the first time a privately funded company operated a passenger airplane of this type with no pilot on board over a populated region, and was an important step in certifying the autonomous platform for repeated, safe civil use on certified aircraft.

“We spent the first portion of our flight test program focused on the C172. We thoroughly tested every aspect of our system in simulation and conducted rigorous safety checks before operating the aircraft without a pilot on board and are now proud to share what we’ve been working on,” said Robert Rose, Co-founder and CEO of Reliable Robotics. “By bringing advanced automation to aviation, we will deliver higher safety, reliability and convenience for cargo operators and eventually for passengers.”

What Is The Future For Autonomous Passenger Airplanes?

The company designed and built a proprietary autonomous platform that can be applied to any fixed-wing aircraft. The platform includes avionics, software, mechanisms, a communications system, remote command interfaces, along with a backup system that has the capability to take over if needed. Following the C172 program, it was adapted for use on the larger C208. Reliable Robotics is now working with the FAA on incrementally bringing this technology to market, having already demonstrated automated landing on the C208 last month.

Reliable Robotics was founded in 2017 by engineers who believe aircraft should fly themselves. The leadership team includes Co-founder and CEO Robert Rose who led flight software at SpaceX and the Autopilot program at Tesla, launching the Falcon 9 rocket, Dragon spacecraft and the first consumer automobile with fully unassisted self-driving capability. Co-founder and VP of Engineering Juerg Frefel led the team developing the compute platform for the Falcon 9 rocket and the Dragon spacecraft. Other senior members of the team have played key roles in the development of the Boeing 787, Airbus A380 and other major commercial aircraft and avionics systems.

The company raised $33.5 million in two funding rounds with $8.5 million in Series A led by Lightspeed Ventures and a previously unannounced $25 million in Series B led by Eclipse Ventures; Pathbreaker Ventures and Teamworthy Ventures also participated. The funding is being used to build components of the remote hardware and software needed to retrofit aircraft and to continue hiring top aerospace and engineering talent.
