And so we took that multibody simulation framework, and based on it we built our own Mars helicopter simulation, put together our own rotor model, our own aerodynamics models, and everything else that's needed in order to simulate a helicopter. That's a system that has been in development at JPL for about 30 years now, and it's been used in a number of missions. HГҐvard Grip: We developed a Mars helicopter simulation ourselves at JPL, based on a multi-body simulation framework thatвЂ™s also developed at JPL, called DARTS/DSHELL. IEEE Spectrum: Can you tell me about the simulation environment that JPL uses for IngenuityвЂ™s flight planning? He summarizes this role as вЂњoperating the flight control system to make the helicopter do what we want it to do.вЂќ Grip also has the title of Ingenuity Chief Pilot, which is pretty awesome. To answer our questions, we talked with JPLвЂ™s HГҐvard Grip, who led the development of IngenuityвЂ™s navigation and flight control systems. Last month, we spoke with Mars Helicopter Operations Lead Tim Canham about IngenuityвЂ™s hardware, software, and autonomy, but we wanted to know more about how the Ingenuity team has been using simulation for everything from vehicle design to flight planning. There will be more flights over the next few weeks, but all it takes is one to prove that autonomous helicopter flight on Mars is possible. If Ingenuity pulls this off, that will have made its entire mission a success. If everything looks good, the first flight will consist of a 1 meter per second climb to 3 meters, 30 seconds of hover at 3 meters while rotating in place a bit, and then a descent to landing.

Before liftoff, the Ingenuity team willВ conductВ a variety of pre-flight checks, including verifying the responsiveness of the control system and spinning the blades up to full speed (2,537 rpm) without lifting off. Ingenuity is scheduled to make its first flight no earlier than April 11. Navigation sensors: VGA camera, laser altimeter,В inclinometer We talk with IngenuityвЂ™s Chief Pilot, HГҐvard Grip, to learn how it all works. With that in mind, the Ingenuity team has been relying heavily on simulation, since thatвЂ™s one of the best tools they have to prepare for their Martian flights. JPL has flown engineering models in Martian atmospheric conditions, and theyвЂ™ve used an actuated tether to mimic Mars gravity, but thereвЂ™s just no way to know what itвЂ™ll be like flying on Mars until theyвЂ™ve actually flown on Mars. Testing the Mars helicopter under conditions matching what itвЂ™ll find on Mars is not physically possible on Earth. If it works in real life, great! And if not, well, you can tweak some stuff in the simulation and try again.ДЇor the Mars helicopter, simulation is much more important, and much higher stakes. Once you think youвЂ™ve gotten everything figured out in simulation, you can always give it a try on the real robot and see how close you came. Here on Earth, simulation is a critical tool for many robotics applications, becauseВ it doesnвЂ™t rely on access to expensive hardware, is non-destructive, and can be run in parallel and at faster-than-real-time speeds to focus on solving specific problems. So the best that the folks at JPL can do is practice as much as they can in simulation, and then hope that the helicopter can handle everything on its own.

It will do so fully autonomously, out of necessity-the time delay between IngenuityвЂ™s pilots at the Jet Propulsion Laboratory and Jezero Crater on Mars makes manual or even supervisory control impossible. On April 11, the Mars helicopter Ingenuity will take to the skies of Mars for the first time.
