It is no secret that most dogs keep a good chase.
And now researchers in Japan use this property to operate the animals remotely without the use of invasive technology.
Images from recent experiments with the system show how a dog can be guided in the direction of an object of interest and can even navigate through obstacles, simply by having it follow a point of light.

A video shared on YouTube shows exactly how the new system works; the dog (in this case a poodle) is provided with a vest with "on-suit light sources", which appear on the ground in the direction in which it must go
According to the Tohoku University team, the new system canine motion control & # 39; toe.
A video shared on YouTube shows exactly how it works; the dog (in this case a poodle) is equipped with a vest with & # 39; on-suit light sources & # 39; that shine on the ground in the direction in which it must go.
In essence, this means that the vest is equipped with a handful of flashlights.
The suit also carries a camera that shows the handler from the perspective of the dog an image, so that the person in charge can see what the dog sees while navigating the space.
Although it may seem simple, the footage shows how well this can work to guide a dog through a complex environment without a person at his side.
In the video the poodle follows the changing light points around two obstacles to get to object "A".
And when the object is approaching to inspect, the handler also gets a clear view.
According to the researchers, this was all done using the remote-controlled system.
& # 39; The dog moved between the desks and arrived at the target location by following the light stimulation specified by the operator, & # 39; says the team.

WHAT DOG GIVES THEIR ULTRA-SENSITIVE FEELING OF SMELLS?
The slimy surface of a corner nose is behind their refined sense of smell.
Moist mucus smells on the nose of a dog & # 39; pre sorts & # 39; by blocking the passage of some odor particles more than others, the team reports.
Brent Craven, from Pennsylvania State University and the team, studied MRI images of the nasal passages of dogs to see how the air traveled through them.
They discovered that different types of molecules were picked up by nerve cells at various points along the airways.
Dogs have many more nerve cells in their nasal cavities than humans and a larger variety of receptors that pick up different chemicals.
This allows them to be trained to detect certain odors, such as those on USB drives.
This type of approach can help to improve the efficiency of dogs used in difficult environments.
While search and rescue dogs may fit into small spaces to gain access to areas that a human handler can not, it is currently difficult to guide them beyond this point.
That is where the light-based system, or something of a similar design, could come into play.
