How can a drone with 4 propellers (as in the photo) fly forwards or backwards. I think the propellers are all on the same level. There is then no propelling movement.
In: Engineering
As others have pointed out, it’s done with independently variable thrust, i.e. Making the propellors turn at different speeds, causing the drone to tilt in one direction.
This is also why 4 (or more) propped drowns are so dominant: using this system you can have the drone move in all 6 degrees of freedom without needing a single movable part (aside from the rotors themselves obviously)
