We implemented a quick, simple way for people to interact with the Flying Machine Arena. A person holds a "wand" with markers on it. Simple wand gestures tell the system what to do.

Is it possible to reduce the negative vertical displacement when you flip the quadrotor? Perhaps if the motors are reversible you could increase the torque by reversing one side instead of dropping it's power.
mkeblx 2 years ago
Yes, it's certainly possible.. by better scheduling the thrust command, etc. Unfortunately the motors aren't reversible and even if they were, fixed-pitch props tend to be horrifyingly inefficient when operated in reverse (let's say 5% of normal lift; the rest of the power gets wasted into drag)

how does the rotor see the wand?
domino14 2 years ago
both the quadrotor and the wand are tracked by a motion capture system (8 cameras with IR strobes above the field).
