The means of automation are becoming ever more densely integrated into our lives. Washing machine, microwave, multivark - and this list can be continued for a long time. But similar automatic helpers can be not only bought in the store, but also made by themselves. Three of them will be considered in the framework of this article.
What is a robot
This is the name of automatic devices that act, trying to copy the principle of movements of living organisms. They can perform various operations that have been prudently implemented with the hardware component and software. Obtaining information about the external world is carried out with the help of sensors acting as sensory organs, which are inherent in living organisms. In this case, there may be a connection with the operator and the ability to process his commands. Their appearance is not tied to a single standard. So, robots are used in production, which for economic and technical reasons are far from human. This term can also be used for software, for example, with the prefix "search engine" or as a game object - "bot".
Home robots
Robotics is such a direction, which in recent years can be seen a significant surge in interest. In many ways this can be explained by heredity (in the Soviet Union, radio amateurism enjoyed considerable popularity). When you create a robotic design at home, you usually do not need a significant investment, which allows quite a lot of people to get themselves into this hobby. In addition, the home robot can perform a number of useful functions, so they are often collected to facilitate life. I suggest that you familiarize yourself with several representatives who can be collected relatively easily.
What is necessary for home robotics
In the technical part, you should have a working place, a soldering iron, solder, rosin and elements that will be used in the schemes. From the theoretical point of view, it is necessary to know what and how to unite in order to obtain the desired result. With the latter there may be certain problems, but then at your service the Internet, where you can ask for advice and get it to bring the moment when the home robot can perform the tasks assigned to it. This topic is quite popular, so finding an answer to your question or asking it on a specialized website will not be difficult. And now let's look at examples of home-based robot assistants.
Automatic backlight
Lanterns serve us as the sun in the dark. This design is useful for those who are often busy hands, as well as for the disabled, who are not always comfortable to use the usual means of lighting. How will it act? An orientation for a robot can be taken infrared beacon-signal, which can be attached anywhere (shirt, shoes, object). For its manufacture it is possible to use LEDs, which generate a signal of the required range. The robot itself can be placed on a wheel platform (located on a hill) and driven by two engines (or one that can turn in two directions). The backlight will be activated by infrared phototransistors. Two switches can be used to power up the device. That this robot-helper for the house does not fall and is not damaged, it can be placed in a PVC tube with additional support in the form of rubber bands. If desired, this design can be easily improved.
Robot cleaner
I propose now to consider a device whose purpose is to clean the room, slowly but surely. This model is a vibrating robot and is developed on the basis of a conventional brush. As a component, you can take a vibrating motor, a standard battery and a switch. Assembly is not difficult. It is necessary to connect the battery to the engine, to it - the switch. Next, the entire structure is attached to the brush and turned on. This home robot begins to vibrate while cleaning the surface. The design has significant prospects for improvement.
Robot-washer windows
Perhaps the most complicated design. Here, in addition to the obvious need for an engine, it is also necessary to ensure that the device can move vertically. To control the entire process, it will be necessary to resort to the help of microcontrollers. To facilitate the design, you can use a battery instead of a battery, and connect the robot to the mains. As a cleaner, you can use a small motor that will constantly move a circular element or a two-side cleaning element. To fasten the structure, you can use small suckers that are good enough to hold the robot, but will not stop its movement (like a gecko).
Conclusion
And it's not all possibilities! Robots for home use can have the widest possible use. And the samples told in the article do not limit your imagination. After all, a person can make up any gadgets. Home-based robot assistants can help with a bunch of other things: so, you can finish the iron so that he can move independently. Or create a hand that will be attached to the ironing board, and move it. As you can see, there are lots of options. And what will be your home robot - it's up to you.
