Analog Control Technology
Difference between ANALOGUE Control and DIGITAL Control
The operational assumptions under theoretical conditions are impractical for drone flight scenarios.
Various variables encountered in flight environments are unpredictable and simultaneously impact drone flight performance unpredictably.
Extreme environmental conditions such as sub-zero temperatures, gusty winds, sudden rain showers, solar radiation(sunspots), thunderstorms,
and other natural phenomena overtakes aerial vehicles developed solely with theoretical knowledge.
Numerous drone technologies are publicly disclosed to encounter complex situations, however by solely applying these technologies will not result in a reliable industrial drone.
The various newest technologies demonstrated by drones in controlled spaces loses its effectiveness when exposed to the complexity
of natural environments. While 'optimization' is a simple concept, achieving it in reality requires advanced integration of technologies.
VORASKY's research team, based in robotics engineering, has developed technology that enables judgment and response
to complex situations using control methods not previously applied to drones.
Cerebrum and Cerebellum(left and right brain)
-VORASKY's Flight Controller
The flight and mission execution of VORASKY drones are carried out in a manner similar to how humans walk.
Among the vast amount of information that humans process while walking, complex calculations are handled by the cerebrum,
while immediate situational responses, such as maintaining balance and avoiding obstacles, are managed by the cerebellum.
These natural and instantaneous responses are based on accumulated information from patterned situations.
VORASKY's autonomous flight resembles the cognition and responses of the cerebellum.

ORIGINAL FC (Flight Control) Technology
Inertial Navigation System
To control the autonomous flight of the drone platform, various sensors such as GPS sensors, magnetometers, gyro sensors, etc., are applied. Among these, the magnetometer plays a crucial role in setting the direction based on the drone's position, employing the principles of a compass, and is the most vulnerable sensor.
Traditionally, if the magnetometer malfunctions, drones are unable to determine their direction, leading to a halt in a hovering state.
In the case of a drone flying beyond the clock range, it may be unable to execute the RTL (return to launch) command. Instead,
it waits for a magnetometer reset for some time or moves in the wrong direction, ultimately resulting in the loss of the aircraft.
VORASKY's drones, in the event of a magnetometer malfunction, utilize the proprietary technology of an Inertial Navigation System.
This system allows the drone to autonomously determine its direction and restore the original path setting even in the situation of magnetometer malfunctions.
Landing Guidance Technology
The situation where both the magnetometer and GPS are rendered non-functional can be critical in an industrial drone solution
that autonomously flies mission over several kilometers.
In the event of GPS sensor failure, VORASKY drones initiate their own landing guidance system.
The drone shuts down the GPS sensor and utilizes triangulation through RF signals to narrow down the distance to the HOME point.
(This technology is part of the advanced navigation systems found in large aircraft,
guiding the landing of an aircraft in situations like clock failure.)
Once the HOME point is captured within the top-view camera area of the drone, the RF landing guidance mode is deactivated,
transitioning into the VISUAL TRACKING mode.
VORASKY's visual tracking technology, derived from precision technology applied in areas like robot soccer,
allows for much more precise landing adjustments than GPS autonomous flight. After landing safely, the drone undergoes a self-diagnosis mode, restoring the magnetometer and GPS sensors before returning to its mission.
ORIGINAL Flight Stabilization Technology
Low Center of gravity/ Aerodynamic Drag Coefficient
VORASKY applies proprietary technologies to maintain a stable flight during flight. During high-altitude flights,
the risk of the aircraft overturning due to three-dimensional winds and gusts is a serious concern.
For drones designed for vertical flight at high altitudes, such as those used for meteorological observations,
the aircraft is shaped in a vertical form to minimize wind resistance. By concentrating the weight center towards the lower part,
the aircraft maintains its flight stability even in free fall situations.
The finalized size and form of the aircraft, determined through thousands of simulations and tests,
not only minimizes vertical wind resistance but also maximizes battery efficiency during high-altitude flights, extends flight time.
The vertical form of the drone is legally protected as intellectual property of VORASKY.
Spatial Representativeness Maintenance Technology (Wind Adaptability)
To stabilize the flight performance of drones, most drone systems have their own methods to cope with wind impact. This concept is similar
to the suspension system in a car, maintaining a solid or soft form depending on the settings.
Since many drones are developed for photo taking, a lot of effort is put to GPS position maintaining to capture shake-free,
high-quality footage. VORASKY drones use proprietary algorithms to prevent unnecessary battery usage for staying in a fixed GPS position,
thus optimizing efficiency.
VORASKY introduces the concept of spatial representativeness used in meteorology,
presuming a virtual spatial volume where a single aircraft can reside.
For vertical weather observation drones, if the drone is within 5m horizontally/vertically/heightwise of the fixed GPS position,
it is considered to represent the space within a 1km radius horizontally and vertically.
Therefore, the VORASKY drone platform flexibly adapts to wind strength within a space that does not compromise spatial representativeness.
It continuously detects and calculates instantaneous wind direction and speed, adjusting PID values accordingly.
In other words, when facing strong winds, the drone adapts assertively, expending minimal energy while flowing in the direction of the wind.
When the wind subsides, it swiftly restores its original position.
With this technology, VORASKY drones ensure longer flight time with higher energy efficiency compared to other drones.
Battery Efficiency Technology
Power Regulator/Battery Thermal Maintaining System
VORASKY drones drones have a longer flight time and battery efficiency of more than 50% compared to ordinary industrial drones.
The proprietary power regulation technology is linked with situational awareness-sequential control technology
to determine the optimal energy efficiency values.
Additionally, VORASKY possesses a unique battery air circulating system technology capable of withstanding extremely low temperatures.
In the case of drones used for meteorological observations, the external temperature drops to around minus 30°C
when ascending to a 1km altitude.
The heat generated by the eight motors is discharged externally at normal temperatures but is redirected internally during low temperatures
to maintain the battery temperature at normal levels.
This thermal maintaining system ensures the drone's battery remains at an optimal temperature, even in extreme cold weather conditions.
HARDWARE Optimization Technology
In theory, assembling a drone by piecing together components is not a challenging task.
However, imperceptible discrepancies can lead to a decline in durability and efficiency over time.
The significant degradation in performances are observed with other drones competitors- supplying platforms and various mission devices separately and are deployed in real industrial usage. Due to these reasons, the performance drop is drastical.
Dust and Water Resistance Technology /
Heating and Ventilation System
Dust and Water Resistance Technology / Heating and Ventilation System
Flying in rainy weather is one of the key strengths of VORASKY drones.
VORASKY products are capable of flying even in intense rainfall of around 50mm per hour.
This level of performance goes beyond what can be achieved with simple sealing.
The temperature difference between the internal battery and boards of the drone and the external temperature creates
a continuous condensation situation.
This is a critical concern if moisture occurs inside the drone body, it can lead to severe damage to the flight control (FC) board.
VORASKY's dust and water resistance technology is integrated with a heating and ventilation system,
preventing external moisture ingress and expelling humid air using pressure differentials.
Controlling heat generated by the motors and preventing moisture in the motors are proprietary technologies unique to VORASKY.
The drone's surface features specific grooves that may appear as mere irregularities.
However, these grooves serve as guiding channels to direct water flow, preventing internal ingress and guiding water away.
The direction of these channels is precisely calculated based on the assumed flight direction and speed,
serving a crucial role during flight compared to stationary conditions.
Durability Test, Noise Shielding Technology
The optimization of VORASKY products goes beyond the mere application of technology.
In the R&D lab, hundreds of motors are intentionally overheated, and the drone is allowed to free-fall to find the optimal balance between efficiency and durability through real durability tests.
VORASKY's optimization encompasses the optimization of individual parts, the overall platform, and the solution as a whole.
Through thousands of repeated flights, all components work together to perform missions, continuously eliminating noise
and mismatch points to find the optimal configuration.
This meticulous process involves eliminating points of noise and inconsistency generated during mission performance,
ensuring that all components work together seamlessly.
This iterative refinement process, achieved through thousands of flight tests, leads to the discovery of the optimal configuration.
Mission Equipment Integration Technology
VORASKY integrates mission equipment as much as possible, driven by the goals of weight reduction, durability,
and battery efficiency since it has effect on the flight control (FC) system.
As a result, VORASKY's technology is developed separately for each mission module based on its specific requirements.
The technology and optimal points of optimization vary depending on the specific mission that the drone is designed to perform.
