Automation tools are increasingly entering our lives. A washing machine, a microwave, a slow cooker - and this list can be continued quite long. But such automatic assistants can be not only bought in the store, but also made by hand. Three of them will be considered in the framework of this article.
What is a robot?
So called automatic devices that act, trying to copy the principle of movements of living organisms. They can carry out various operations, which were prudently implemented using hardware and software. Obtaining information about the outside world is carried out using sensors that act as sensory organs that are inherent in living organisms. In this case, there may be a connection with the operator and the possibility of processing 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 be used with respect to software, for example, with the prefix “search” or as a game object - “bot”.
Home robots
Robotics is such a direction with respect to which a significant surge of interest can be observed in recent years. This can largely be explained by heredity (in the Soviet Union, amateur radio was very popular). When creating robotic designs at home, usually no significant investments are required, which allows a fairly large number of people to get such a hobby. In addition, a home robot can perform a number of useful functions, so they are often assembled to make life easier. I propose to get acquainted with several representatives that can be relatively easy to assemble.
What you need for home robotics
In the technical part, you should have a workplace, soldering iron, solder, rosin and elements that will be used in the schemes. From the point of view of theory, it is necessary to know what and how to connect in order to obtain the desired result. There may be certain problems with the latter, but then the Internet is at your service, where you can ask for advice and get it in order to bring the moment when the home robot will be able to perform its tasks. This topic is quite popular, so finding an answer to your question or asking it on a specialized site is not difficult. Now let's look at examples of home assistant robots.
Auto backlight
Flashlights serve us as the sun in the dark. This design will be useful for those who often have busy hands, as well as for people with disabilities who are not always comfortable using conventional lighting. How will she act? A reference point for the robot is an infrared beacon signal that can be attached anywhere (shirt, boots, item). For its manufacture, you can use the LEDs that generate a signal of the required range. The robot itself can be placed on a wheeled platform (located on a hill) and set in motion using two engines (or one that can rotate in two directions). The backlight will be activated by infrared phototransistors. To bring into working condition, you can use two switches. So that this home assistant robot 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.
Cleaning robot
I propose now to consider a device whose purpose is to clean the room, slowly but surely. This model is a vibro-robot and is developed on the basis of a conventional brush. As the constituent elements, you can take a vibration 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. Further, the entire structure is mounted on the brush and turned on. This home robot starts to vibrate while cleaning the surface. The design has significant prospects for improvement.
Window washer
Perhaps the most complex design. Here, in addition to the obvious need for the 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 not a battery, but connect the robot to the mains. As a cleaning device, you can use a small engine that will constantly move the cleaning element in a circle or in two directions. To attach the structure, you can use small suction cups that are good enough to hold the robot, but will not stop its movement (like a gecko).
Conclusion
And these are not all the possibilities! Robots for home use can have the broadest possible use. And let the samples described in the article do not limit your imagination. After all, a person can make any gadgets. Home helper assistants can help with a bunch of other things: for example, you can modify the iron so that it can move independently. Or create a hand that will be attached to the ironing board, and move it. As you can see, there are a lot of options. And what will be your home robot - it's up to you.
