A quadcopter mission, flown before the drone exists

A complete quadcopter wired from library parts into one co-simulation, its flight controller closing the loop around NVIDIA Isaac Sim rigid-body physics — and a real take-off, hover, climb, descent and landing recorded from that loop.

The device, before it exists

Real dynamics usually only appear on the bench, after the parts have been bought and the airframe built. Here the drone is a system of functional models from the start: radio, flight controller, ESCs, motors, propellers, battery and airframe, each a real component record with its model attached.

The airframe block hands off to NVIDIA Isaac Sim. Per-rotor thrust and torque from the functional models drive a 6-DOF PhysX rigid body on the GPU, and pose, IMU and GPS stream straight back into the running system.

The recorded mission

A closed-loop mission recorded from the co-simulation: an FMU flight controller (radio → FC → ESC → motors → props) around rigid-body physics from Isaac Sim, captured with exact sim-time stamps. No keyframes.

Take-off
The radio sends an altitude command; the motors spin up and the PhysX body leaves the ground.
Hover at 2 m
The first hold, with a small honest lateral drift left in the data.
Climb and hover at 5 m
A second altitude command; the airframe follows it and holds.
Controlled descent and touchdown
The drone comes down under control and lands; the recording then shows it at rest.

Watch the physics agree with the math

Live scopes read the signals streamed back from Isaac Sim across the whole mission — thrust, motor rpm, battery voltage and state of charge, altitude command and airframe position.
