In addition to touch, human beings also have many powerful sensory systems, such as vision, hearing, and smell. These senses, which were originally on the human body is very important, have gradually been applied in various fields that can benefit the public due to the advancement of technology. Let’s see how they are implemented on the machine.

Eyes can be said to be a very sophisticated optical system. When light enters the eye and reaches the retina, it will form a clear impact, and then transmit the information to the brain through the optic nerve. Finally, this information will be converted into vision, and we can memorize, learn, and gain experience through the "seeing", therefore, the vision has a great influence on our actions.
A machine can use a monitor or a camera as its eyes to capture the surrounding objects and transmit them to the computer, and then the computer will analyze and identify it, after that, the machine can know the shape, distance, size, color, etc., and finally identify the completed information and accessing it. When the same item appears next time, it can be identified immediately without having to analyze it again.
With other different senses, the machine can do more things. It can know the location of objects in the environment through vision, and with the assistance of programs, it can even avoid obstacles. When applied to robots, it can add a human identification system to distinguish guests and judge each other's emotions, to maintain good interaction with humans.
Robots with vision can better replace human beings to be in dangerous or complex work, such as large-scale scanning, can collect more information, and even work in dark, strong, or high-temperature environments, and no matter how long the working hours don't feel tired. The applications brought by machine vision are very diverse which not only in robots, but also in document recognition, medical engineering, aerospace telemetry and other fields. It is a very important technology that is worth looking forward to development in the future.
Hearing and speaking are the main channels for communication between people. We can hear sound through our ears because the sound waves generated by speaking are transmitted to the eardrum in the ear, and then decoded by the auditory cells and transmitted to the brain. Knowing what we're hearing, we can tell what's being said, other sounds (music, wind, crashing, etc.), and exactly what we want to hear, even in loud or with multiple people talking at the same time.
In fact, it is still very difficult for the machine to achieve the sensing of human hearing. Therefore, the main purpose is to recognize human speech. For example, when the robot hears the sound, it can track the speaker and the source of the sound, analyze the sound, and then find the corresponding action. In speaking, it is necessary to establish a database to deal with the sentences heard. Everyone should have used a voice assistant (for example: Siri) and can talk to it to get the reply of the information, and such a response must be done a lot of learning can be useful in areas such as service, family or companion care in the future.
The smell is made up of chemical molecules. There are about a thousand olfactory receptors in the human nose, each of which can identify a specific group of compounds and send a message to the brain to let you know what the smell is now, and the machine is also through the sensor to distinguish smells, even the sensitivity can be much higher than humans, and it will not be limited by physiological influences to reduce the sense of smell. Common sensors such as smoke detection can prevent fires. Many teams have also developed their sense of smell to find explosives, identify the smell of human sweat, etc., so that many dangerous or disaster relief work is handed over to machines.
With the advancement of science and technology, machines can do more and more things, and the scope of application extends from industry to all walks of life, not only touch, but also vision, hearing and smell can be realized on machines, which allows machines to do some dangerous or difficult tasks, people can develop on things that require more brainpower and more value. These machines also bring better life experiences and help the public. There will definitely be more amazing technologies and applications in the future, which are worth looking forward to.
