Very fast UAV's 4 U

Raytheon Active Kill System (1 min 3 sec)

So this video of a guided missile shooting down another rocket got us thinking, a missile that flies up, turns 90 deg, & flies sideways in a fraction of a second is a super high speed UAV. What else can U do with a super high speed UAV?

Maybe instead of massive vehicles with massive batteries & hour long flight times, U have tiny airborn robots that take off, perform tasks in a fraction of a second & land with just a tiny amount of energy.

Used to wonder if there was a way to launch billions of tiny payloads into space real fast, each payload consisting of maybe a fraction of a gram of raw materials & launched using lasers or some super cheap vehicle. Then these billions of tiny payloads would self assemble in space to form massive structures.

What if U could put a small rocket in a handheld launcher & make it fly out 1m, reverse direction & fly back real fast. Maybe U could make it fly out & back hundreds of times in a second. Every time it flew back to the launcher it would recharge. A perpetual 1m linear orbiting rocket guided by a handheld launcher. U could aim the handheld launcher & the rocket's 1m linear orbit would always point where U aimed it.

Maybe instead of a rocket, it was a mirror with some mode of propulsion & U beamed a high powered laser at it to make a laser saber that was bounded by the rapidly oscillating, flying mirror. Not as clumsy or random as an M16. An elegant weapon for a more civilized age.

Take a look at this.

Ever closer to rate damping (0 min 36 sec)

Managed to get the cyclic oscillations overdamped on the bench with a few more tricks. Added integrals to the PIC rate damping code. That got a single propeller to keep it level using rate damping alone, but didn't work with 2 propellers.

Updated the damping output as soon as the analog signal for each gyro was updated, rather than waiting for all 8 analog signals to update.

Fixing a bug in the configuration upload also helped.
