The AU-A7 HARPIA was designed with the intention to be used as a support unit for armored squadrons and infantry units. Though the Harpia is relatively light on weaponry, its heavy armor, maneuverability, and stealth all make up for the absence of heavy weaponry. However light the weapons are relative to the Harpia’s weight, it is in no way lacking in firepower. On either side the Harpia there are two weapon stubs which can rotate vertically independent from the main body. A typical load-out on either stubs are a MATGM-12 and a dual 30mm auto-cannon, though more variants exist and are easily changed based on mission circumstances. All stub variants have 16 smoke grenades available as well as 8 grenade launcher hard-points.
At first look most would speculate the seemingly unbalanced appearance that the Harpia presents, though that is not the case as it can easily recover from high force impacts from almost any angle and it can traverse in almost any environment. With the revolutionary software from QZK called ALICE (Adaptive Locomotion and Improvised Calculated Execution) the Harpia is considered the first truly ‘self-aware’ articulating unit. ALICE can detect every joint’s torsion, angle, and vertical stress in addition to sensing ground surface tension and center mass and adapt to the sensory information accordingly. In order to navigate effectively ALICE is equipped with multiple LiDAR sensors on the forward and rear optics system capable of making a basic 3D image as it moves. In conjunction with linear and radial gyroscopes and ALICE the Harpia has been unsurpassed by any free standing articulation in the past and is likely to be the leading software for the next three generations of articulation units. The AU-A7 HARPIA has been colloquially named “the harpy”

(please forgive grammatical errors in the information below)

-Ejection-small high explosive charges eject the cap in the case of a major engine malfunction.

-Engine-Rear hatch enables engineers quick access for critical repairs
on the move, basic maintenance can even be achieved by the pilot in
any circumstance where engineers are not readily available.

Double turbine engine gives high torque output to the legs. Though the joints
are less responsive than most MMSR (micro molten sand reactor) designs the engine still offers a high TWR
(torque to weight ratio) giving it more speed and durability while retaining a respectable range.
redundancies prevent mechanical failure also making it as reliable as most MMSR designs.

RAOE (rapid atmospheric oxygen extraction) technology significantly increases efficiency by the extraction of
pure oxygen from the atmosphere for internal combustion during the compression phase. Spooling up the RAOE allows
for a instant/short lived injection of compressed pure oxygen for increased sprinting speed as well as temporary operation even
while the primary air intake is disabled.

The primary turbine engine offers a similar stealth ability in comparison to MMSR designs. at full output
the engine is no louder than a standard v-8 engine at 1000 RPM. The exhaust vents are also highly distributed and absorb 85% of all exhaust
heat. The ejected exhaust above the exhaust vents never reaches 5.5 Celsius above ambient temperature.

balance-Two DU (depleted uranium) rods shift the center of the mass relative to the 'dry-mass' (the mass that the
vehicle would otherwise have without the rods) of the vehicle using activated magnets. advanced computers manipulate the joints
and in conjunction with the DU rods allows for an environmentally adaptive stance even after
receiving heavy damage. overall there are 3 balancing rods/ring implemented for yaw torque, forward-back and for side-side motion.
Most of the force associated with balancing from the rods (and yaw ring) comes from the extremely quick reaction time, if necessary the
rods can push the center of mass 3 meters forwards of the center dry-mass for aprox. .23 seconds.
unfortunately the proportion of the DU rod's weight is significantly lower than that of the rest of the vehicle so a center of mass
shift can only change by about 35cm after the main rod is fully displaced.

Stubs-two stubs on either side of the vehicle allow for various actions, especially offensive and defensive capability.
Both of the stubs always have the weight distributed so as to not interfere with the balance of the vehicle.

feet-the LIT feet (low impact tred) allow for very low probability of IED impact

software-ALICE (adaptive locomotion and improvised calculated execution)
Unlike many conventional AU (articulating units) the A7 is extremely stable
even in conjunction with the LIT feet. If it were not for its high center mass it
would in face be more stable than most wheeled vehicles. some of the many ways it
achieves this stability is by counter stepping, adaptive self awareness software
and miniature hind legs that branch of from the 3(9)D (lowest) leg segments.

Optics-the triple optics configuration grants excellent depth perception and field of view. Central to the triple optics is a DCL (data collection LASER)
which can measure and detect material, barometric pressure, range, depth (to a certain precision), temperature and various other useful parameters. In the unlikely case
of receiving debilitating damage to the optics protective lids slide over and a small back door is open for the pilot to replace a new optics system. for extra situational
awareness a rear view camera is also available.

undeployed-while undeployed the A7 is extremely small and designed to fit in common airdrop vehicles
for parachuting such the C-130.

body core serv. ^ leg 3(9) +15° -15°

-2x medium weapon bays, variants include: a MATGM-12,
a dual 30mm auto-cannon, a non-lethal water cannon.
all weapons bays have 16 IR smoke grenades and are
of equal weight and center of mass.

-8x dual grenade launcher hard-points (total of 16 grenades)

-32% reactive armor surface coverage (mostly critical areas)

Very interesting shape. I am curious though, how come you decided to give it a bi-pedal chassis instead of a wheeled design like a tank? Would it not make sense to offset the relatively high center of gravity by spreading more mass outward?

i was thinking about adding some wheels or tracks to the mid leg section, never got around to it though.

To brow a line from Tony Stark, 'I want ONE!!'. Get work, great ideas and details man.

thanks very much!

Did you ever play chromehounds? If not I would highly recommend it if you get the chance.

The real problem with tiny feet is ground pressure. You would not be able to take this thing into places where it should theoretically outperform tanks, which is a dense urban environment. Those stiletto heels would punch right through pavement, and crack concrete and your ability to mount elevated parking garages, set up on roof tops and such would be diminished.

i doubt it would have trouble on pavement, perhaps on sand or deep mud but most other surfaces not so much.

Hell nicely done man! I love ure artwork. And I gotta say, this AU-A7 kinda, just barely kinda looks like in a way the US team's Mech off from Battlefield 2142. But in anycase, love the back part of the AU-A7. Keep up thee paste. :D

indeed it was inspired by the L5 Riesig, I didn't really reference the image while i was working but the overall shape is what i based it off of.
Axonn5 Featured By Owner Aug 2, 2013
Np man. :D

I know what u mean, and I know that u wouldn't. ;) Like me, I just draw art like without looking at something like fully bcuz I want it 2b in my mind of what the pic would look like. But yea I getcha.
