I got this idea while playing with a toy helicopter that has
two counter-rotating rotors which allow for yaw control.
Before I get into it - yes I did google and search. There are
other ideas for 'gyro stabilized' and target-tracking small
arms, but I don't think this one has been posted yet.
take a lightweight plastic handgun. The lower the
mass the better. On the bottom of the frame, attach a box
containing four small flywheels attached to electric motors
and some electronics. The gyros will be mounted in 2 pairs
one oriented vertically and one oriented horizontally. The
two flywheels in each pair will spin opposite directions, and
incorporate a brake on their axle. Using the same principal
as the toy helicopter if you suddenly change the speed of
of the flywheels by applying the brake you can apply a
to the whole machine. Four flywheels spinning at high RPM
should allow the gun to be controlled on two axes, pitch
yaw. Now you're probably thinking that in order to move a
whole gun the flywheels would need to be large and
cumbersome. But the goal is just mild stabilization not
complete control, so 4 high rpm flywheels and a light
gun should be barely any heavier than a normal pistol with

there is a target acquisition camera. Software uses the
camera to detect contrast changes and motion, identify the
"center mass" of the target, lock onto it. The targeting
is a relatively narrow range in front of the barrel, so it will
only lock onto something the gun is actually pointed at. It
then controls the gyros to torque the gun back and forth
attempt to line up the barrel with the target. This type of
software is WKTE and fitting it into a gun should be no
problem with modern electronics. The design incorporates

Not even the same idea - The buttons are not even less than sure of themselves...

[Maxwell] has a very tasty idea...

The same, only in reverse. Probably more practical. [Custardguts, Aug 08 2015]
||Interesting. With the counterspinning gyros, will this
prevent the gyro effect of trying to move the gun in one
direction resulting in its moment tilting it in another?
||" the shooter can easily depress a button on the grip to take manual control "
||Yeah, a lot of buttons are easily depressed. There's no medication or therapy available for them either.
||" There are other ideas...but I don't think this one has been posted yet "
||There may be a good reason for that.
||//There may be a good reason for that//
||Yes, I'm so smart I came up with it before everyone
else. Or did you mean a different reason?
||Well, I'm not trying to depress any of your buttons, but...
||This seem unnecessarily cumbersome. Why not fit
the gyros onto the person you're trying to shoot, and
get them to track the aiming-point of the gun?
||I was looking forward to browsing geekinternetmarket.com to find gyroscope-mounted body suits there, [normz].
||// take the shot when someone is smiling. //
||That would be the "Ferguson Police Special" model, presumably., with the shooter being the one doing the smiling; the shootee obviously doesn't have much to smile about, if anything ...
||See link to Tracking Point system. This one is for longarms, and works almost opposite to what you propose (but works rather well).
||It doesn't try to influence your aim, it simply pulls the trigger at the right time, when your natural variation in aim aligns with the target. I would bet miniaturising this system would be more likely to work, than what you have proposed.
