From 2001 to 2006, Grip studied for a five-year engineering cybernetics master's degree, and from 2006 to 2010 a PhD at the Norwegian University of Science and Technology. During his studies he was recognized for outstanding academic performance in engineering studies, as well as having the best master's thesis in 2006 in Norway within the field of control and automation.[5][6][7]
Grip's master's thesis was titled Nonlinear Vehicle Velocity Observer with Road-Tire Friction Adaptation. The dissertation focused on real-time estimation of dynamic variables for use in safety systems in cars, such as anti-lock brakes and electronic stability program. Automotive corporation Daimler AG showed interest in Grip's work,[8] and hired him for a contract project at the Daimler Group Research & Advanced Engineering while employed as a scientific researcher at SINTEF ICT from 2007–2008, where he continued researching anti-collision systems for cars.[9]
In 2010, Grip started working as an adjunct assistant professor at the School of Electrical Engineering and Computer Science at Washington State University,[10] where he conducted an independent research project with a grant from the Research Council of Norway.[11]
Since 2013, Grip has worked as a robotics technologist in the Guidance and Control Analysis Group at NASA's Jet Propulsion Laboratory at the California Institute of Technology. He led the Mars Helicopter Guidance, Navigation, and Control team,[12][13] where he designed algorithms and software that helped control and guide the martian helicopter Ingenuity. Grip's role as chief pilot included planning the flight, constructing command sequences, and analyzing the flight data for the helicopter.[14] Other team members that took part in the helicopter project included program executive Dave Lavery, chief engineer Bob Balaram, and project manager MiMi Aung.
On April 19, 2021, at 11:30 UTC, Grip flew Ingenuity for 39.1 seconds, raising the helicopter vertically about 10 feet (3.0 m), rotating in place 96 degrees in a planned maneuver, and landing it successfully.[17][18][19]
Grip's research interests include nonlinear control and observer design, navigation and vehicle state estimation, decentralized control of heterogeneous systems, and structurally based design techniques for stability and robustness of nonlinear systems.[20]
