Data-Driven-Dynamics: Learning vehicle dynamics for simulations

Jaeyoung Lim

Simulations are a great tool to test and develop your vehicle safely. However, when creating a vehicle simulation, it is always a challenge to configure the simulated model to behave as the real vehicle. Normally, this is a hand tuned process including dedicated maneuvers and diving deep into flight logs.

Therefore, we have created [Data-Driven-Dynamics](, which automatically learns a parameterized dynamics model directly from a set of flight logs from a real vehicle. (uLogs)

Video below shows the vehicle flying in a PX4 Software-In-The-Loop simulation with estimated dynamics (note that the props are not spinning)
