Patented color ball and marking system for drone installation SKYMARKER®
~ The world first! Sky Robot Develops New Technology to Accelerate “Empty Industrial Revolution” ~
Acquired worldwide patent for drone-mounted marking system “Sky marker” Enable accurate marking. Scheduled to be released late September

SKYMARKER® (Sky Marker ®) which got the world patent launches a color ball filled with paint during the flight and fires at the targeted part in inspections of structures and buildings, accidents and disasters, etc. It is a marking system for coloring and specifying.
With this system, it is possible to quickly find targets by instructing the workers heading to the site in a rough position.
Also, you can maintain the target continuously visible.
The accuracy is high even outdoors, and the deviation is within 5 cm for the target part 10 meters ahead.

SKYMARKER® technical background

  • A color ball formed by encapsulating a paint in a capsule-shaped outer shell makes it possible to mark a target from a remote place by destroying the outer shell with the shock impact.
    However, due to the above-mentioned structure, when a large inflation pressure is applied, since the outer shell of the color ball is destroyed before or during launch, there arises a problem that excessive pressure can not be applied to the bullet at the time of launching It will be.
    For this reason, it is necessary to suppress the shooting power to the extent that the outer shell is not destroyed, but in the actual marking work, it is requested to develop a launch device keeping a longer flight distance with the same launch pressure.

  • Also, in recent years, it has been drawing attention in various fields to make drones fly for unmanned exploration and inspection, but drone is different from the structure installed on the ground, the object on which the color ball launcher is mounted (Drone) itself is levitating in a state floating in the air.
    For this reason, the force which receives the shock of the shot or the force which produces the reaction becomes extremely low, and it is greatly affected by the impact caused by the ejection of the high pressure gas at the time of firing the color ball. Therefore, It is extremely difficult to get the target accurately hit.

As a technique to solve such problems
SKYMARKER® was developed.

SKYMARKER® effect / feature

The infrared thermography camera mounted on the drone identifies the abnormal part of the solar panel.

It is possible to find targets quickly

Color balls are marked on the target object by collision of the outer shell with the impact colliding with the target object, and the paint sealed inside scatters and adheres to the target .
For this reason, it is possible to discover the target quickly by merely instructing the workers heading to the site about a rough position.
Also, you can maintain the target continuously, in a visible state.

It is possible to find targets quickly

Change the size and shape of the color ball by purpose

The size and shape of the color ball can be changed to the desired form according to various uses depending on the distance to the target object, the inner diameter of the barrel, the expansion pressure of accumulated air, and so on.

Change the size and shape of the color ball by purpose

Highly visibility photoluminescent paint even during daytime is also crime prevention

カThe paint to be sealed in the color ball can be changed according to the application, such as inspection of the structure or rescue work at the time of accident / disaster.
For example, by using paint sealed in a color ball as a phosphorescent paint, it is possible to easily see the marked part even at night. Also, phosphorescent paint is highly visible even during the day, and can be used for criminal identification even for purposes such as crime prevention.

Highly visibility photoluminescent paint even during daytime is also crime prevention
It is possible to take a longer effective range.

It is possible to take a longer effective range.

About flight accuracy of color ball

Regarding the flight accuracy of the color ball, in order to prevent the parabolic line from descending toward the ground due to a decrease in flight speed and attraction, the discharge flow velocity of the compressed air ejected from the compressed air accumulation tank Controlled with an adjustment protrusion provided on the inner circumference of the inner circumference of the base of the barrel, apply backspin to the color ball launched from the color ball launcher, generate lift force, and extend the effective range.

It is possible to accurately mark the target

Electronic control of the expansion pressure of the compressed air accumulation tank with an electromagnetic valve and control of the outflow pressure of the compressed air to be discharged by the adjustment protrusion to increase the flow velocity at the lower part in the barrel makes it possible to provide a back It is a configuration to spin.
In addition, by providing a rearward injection exhaust pipe, it is possible to cancel the recoil of the launch, suppress the jumping up of the barrel, and accurately mark the target.

Markable even in places difficult to reach by human power

Since SKYMARKER® can secure a long effective range, it can be mounted on a drone to inspect a huge building, marking it in a dangerous place, or for a test or rescue from a remote place in case of a disaster Even marking etc. where it is difficult to reach by human power, it will be possible to easily mark with color balls.

Markable even in places difficult to reach by human power
It is a recoil absorbing type launch device that allows drone to perform highly accurate marking without being affected by the collision impact of color ball shot.

Marking not affected by recoil

With the launch pressure, the backspin effect does not decrease due to wear even in repetition of long-term firing operation without destroying the outer shell of the color ball, extending the effective range with the same pressure as the conventional inflation pressure, It is possible to carry out marking by suppressing shock of launch and being not affected by recoil.

Marking not affected by recoil

Reduce recoil reaction

It is a color ball launching device which is able to reduce the recoil of launch by providing a rear injection fuel pipe and discharging compressed air exhausted backward simultaneously with launch.

Reduce recoil reaction

Formable from various materials

Since it is constructed to fire using compressed air inflation pressure, there is no large explosive power or heat generation, and the barrel can be made of various materials such as light alloy and resin.
