Autonomous robot

A self-governing android performs tasks or behaviors with a high degree of autonomy. Of course, without a human being involved. The more autonomous robots are used particularly in:

  • Places where conditions make human presence unfavorable: space research, air with a high level of pollution, water with polluting waste, among others.
  • Tasks that can be carried out with efficiency, precision and speed: merchandise delivery services, packaging, industrial assembly, etc.

A automaton fully autonomous can:

  • Get information about your environment.
  • Work for a long period of time.
  • Move anywhere on your own.
  • Learn the best way to perform a task in any circumstance.

How much do the most autonomous robots cost?

The new more autonomous robots, with their complete equipment, can cost between $ 50,000 and $ 80,000. In addition, if specific peripherals are added for an application, its value increases between $ 100,000 and $ 150,000.

But if what you want is to save money the used robots they can be worth half as much as a new one. Its value can range from $ 25,000 to $ 40,000. Its cost is increased by adding components for certain applications, where it can be worth $ 75,000.

Facial recognition and artificial intelligence




Do you have a cell phone that allows you to access just by showing your face? Have you ever needed to take a photo to enter a site or an application?

We are in the digital age, where technology increasingly takes over our daily habits. In this, the use of facial recognition as a security method is a latent reality.

If you want to know about this system, its operation, dangers and the importance of its combination with artificial intelligence, read this post. We will be addressing these issues.

All the details about artificial intelligence. Machines programmed to determine human life and death.

What is facial recognition?

Facial recognition 4

Facial recognition

Facial recognition is a very recent technology that is giving a lot to talk about today. Even though it has existed for a few decades, today its use has proliferated enormously.

It consists of a scanner that verifies the identification of the owner of certain technology. It is based on biometric data (features of your face) to decide if you are who you say you are.

For its operation you need a device with a camera. Thus it obtains images with the necessary data to register the identity of the subjects.

It should be noted that, unlike other types of security such as password, facial recognition employs mathematical patterns.

Its efficacy and safety have been widely proven, hence it is being used more and more in different areas.

For example, it is widely used to identify celebrities at public events. It is very likely that you have also seen it as an authentication system in cell phones.

Likewise, it has been used to link images of companies, the media and entertainment. Finally, an extremely important use is for the identification of criminals of any kind.

How does facial recognition work?

Facial recognition 3

They need to have a reference image

Facial recognition systems need to have a reference image. Therefore, first of all, they make a two-dimensional or three-dimensional capture in which the facial features are detailed.

The image goes to the database and could be used on any occasion. Then you have the option to identify yourself thanks to facial recognition.

  1. You will first have to stand in front of the device
  2. Then it scans your biometric features
  3. Finally, determine whether or not you are the same person previously photographed.

In many cases, an Internet connection is required to carry out the procedure. This is because the database is not always in the internal storage of the device.

Due to the fusion of the security system with artificial intelligence, its effectiveness has grown even more. It allows the process to develop instantaneously and that there is not the slightest margin of error.

These are the amazing 10 technological advances that have propelled humanity

Artificial intelligence applied to facial recognition

A few lines ago we mentioned the important fusion between artificial intelligence and facial recognition. This combination has made the system more effective and safe.

The first tests were developed in the project Facial Recognition Grand Challenge in 2016. At that time, experiments were carried out with novel methods to analyze biometric data.

As a result of the study, it was even clearly differentiate the features of two identical twins.

The advantages of this combination are:

  • Simplification of work
  • Greater safety and efficiency
  • Ability to identify faces in photos and moving images
  • Uses infrared light
  • Generate patterns for each person.

Dangers of facial recognition?

Facial recognition

There are countries in which they use facial recognition from street security cameras

Being such an effective and avant-garde technology, today governments want to use it in any field. There are even countries where they use it from street security cameras.

Using facial recognition as a method of urban security is not entirely negative. Help fight crime and solve many police cases. However, there is the fact that such cameras can detect your face in a crowd with great ease.

Will it be feasible for governments to have all your data?

It is a concern of many citizens having to go out on the street and expose themselves to the fact that, at any moment, they can take your identity. They talk about the similarities with Big Brother and the violation of each person’s personal rights.

Every country has its own regulations in this regard. These indicate how ethical and permissible it is to use the data obtained in this way against a person.
