This does not mean Reliable Robotics makes use of a regular autopilot system. “I wish we could have bought an off-the-shelf autopilot,” said Rose. “The fact is nobody makes an autopilot that can handle all phases of flight: taxi, take-off and landing,” he added. “The other problem is that they don’t handle failures gracefully… If you’re going to automate the entire aircraft, and you’re not going to have a pilot in there, then you need something that can not only detect failures, but also respond to them immediately. So, we set out to go built it. A lot of the methodologies and principles that we’re following echo what we developed at SpaceX.”
In terms of equipment, what exactly does it take to automate a small cargo aircraft, such as a Cessna 208? “We have developed custom computers, software, mechanisms, communication systems, ground control centres, back end data network for transferring all of the data between the aircraft and the control centre…” Rose mentioned that “actuators are another thing that we have spent a great deal of time developing. You can’t buy actuators of the shelf that are suitable for automating the aircraft to this degree.”
Looking at the rate at which Reliable Robotics has achieved its milestones, it is impressive how quickly the team has made progress. “This is really a testament to the simulation capability that we have developed,” remarked Rose. “We felt from the beginning that it was of crucial importance that we build a simulation capability for our aircraft that the world has never seen before!” The team was able to model flight dynamics with great accuracy, with the result that systems worked remarkable well during actual test flights, saving a significant amount of time.
