"Not *only* useless to non-military users, also useless to the vast majority of military users, who have always had the option of using encrypted codes technically, but bureaucratically, distribution of the codes was such a secret that it was limited…"
"They determined that they would use 'Robots' to clean it up, but the radiation destroyed their electronic circuits. The robot team didn't want to admit failure. So the project used what are euphemistically termed 'Bio Robots'"
"Deadbeat admin here.
What happened was a combination of an overwhelmingly large amount of captcha-defeating spam, and efforts to fight it which took up increasingly large amounts of my time... right up until one extension broke Mediawiki for…"
"They're certainly useless for long-term energy storage, so the intended goal would be for sub-second 'bursts' of very high current to or from the motors, in order to rapidly change the RPM. The question then becomes - are you holding off on pushing…"
"Here's how you do an endurance 'record' run, in order of importance:
1) Saturate payload capacity with battery, sacrificing maneuverability, useful gear, and wind compensation
2) Tune. Test combinations of prop, motor, and battery until ideal…"
"So my impression is that an ideal mount would be something along the lines of: four LIPOs mounted at the ends of a rigid cross for a large moment arm, with the PCB at the center, attached to the rest of the frame by tight rubber bands which have a…"
"It may be time that Ardupilot addresses better altitude sensing. We could be using a barometer / GPS fusion approach that would:A) Detect altitude from GPS at launch, use that to calibrate pressure sensor for baseline air density gradient, in order…"
"Items 1-4 are not objectively good: it is entirely possible to have those numbers go *too far* for a given AUW, number of motors, prop, and voltage. Finding the optimal solution involves varying these numbers along with props.
"The expense and weight of an Aerial Laser Scanning system (ALS) is not just a rangefinder. It is the mount, the rotating mirror, the optical encoders that track this mirror, the memory and data processing chips, the equipment pod for the unit…"
"Another facet to this question: Drones specialize in low-altitude, high-resolution remote sensing.
Evaluating these remote sensing technologies requires not just the track of the vehicle, but very solidly constrained GPS points on the ground. …"
"I was under the impression that foam flying wings in the RC community were praised for their efficiency at high speeds, their wide speed envelope (ability to 'float' to a landing while still moving fast in the air), yaw stability in high winds, and…"
