Robot vacuum cleaner with your hands at home: especially manufacturing

Modern man can be difficult to maintain cleanliness in the home. However, the technique has gone far ahead; appeared robot vacuum cleaners operate cleaning the apartment yourself. They cost considerable money, but you can try to create such a device yourself.

Particularly of manufacturing the robot cleaner home

For manufacturing you need at least an amateur skills, because the robot cleaner production process requires time and patience. But the finished device will help you save money at first, and then the time and effort spent on cleaning.

theoretical aspects

To successfully make a robot cleaner with your hands, you need to understand the essence of his work from the inside. Let's look at a few rules that will ensure the proper functioning of equipment:

• A robot must take the form of washers, drive traffic to the correct course;

• Wheels are placed along the diameter of the vacuum cleaner so that it can carry out reversals;
• The center of gravity is optimal on wheels, but can also be located next to them;
• The average speed of the machine 25-35 cm / sec;
• Bumper contact size of at least 0.5 on the circumference - a mandatory component of the robot cleaner;
• Charging homemade robots must be carried out on the charger, no need to disassemble the device;
• Dust and debris should be collected in a separate container, which can be removed and cleaned.

How do drawing

Modern Internet resources allow for the assembly of the robot cleaner without drawings and other schemes. But to understand the structure of the machine you recommend this drawing to make to visualize the internal structure. The fact that the parts for the robot to pick up easier than competently arrange them inside. We will present you a rough drawing of the future miracle of technology:

Tip! mark in the drawing all the components of the future cleaner and exemplary dimensions. The arrows indicate the direction of air and suction of dust particles. Visibility - one of the steps to the success of the future assembly.

To chart, let's determine what components will be needed in the work:

• Arduino board - "the brain" of the robot of the future;
• Turbine the old cleaner;
• The engine is small in size (you can take an old computer cooler);
• Rangefinders - 2 pieces;
• Wheels (preferably 1 and 2 of conventional rotary) motor with gear;
• The controller (motor);
• 3, the lithium battery;
• The charge controller;
• wire;
• Thick cardboard.

Important! If you can not find the old turbine - it is possible to make the most out of cardboard. The circuit is attached.

Features of the assembly

Collecting robot vacuum cleaner with your hands at home, log on to the organization of power. To do this, charge the batteries using the supervisor. Next you need to create a motor control drive system. It is best to use the on-chip module type L298. To adjust the speed to pin ENA or ENB need to apply a PWM signal. To change the direction of rotation, the post oppositely signals IN1 and IN2 for one and IN2 and IN3 for the second engine.

Then, the motor must be connected to the Arduino. Cardboard make a circle, and then attach it to the wheels (diameter count by "stuffing" - about 30-35 cm). On both sides using conventional tires, but with the bevel gear, and between them behind - turn the wheel for maneuverability.

On manufacturing grounds Mount the entire electronics and the cleaner unit. Rangefinders attach the front.

A further step is to construct the turbine blades therefore remove computer cooler and glue it to the hot melt adhesive from the old turbine cleaner. Secure it exactly in the middle: we do not need imbalance.

The side walls of the vacuum cleaner can build your own. Importantly, do not forget: it must have a cylindrical shape.

testing the device

After assembly of the vacuum cleaner be sure to check his work. He will have to do the following: go forward to the obstacle. If the path meets an obstacle, the robot will move backward, making a U-turn under the undefined angle and goes in the wrong direction. And also do not forget to check the suction power of the device. If it works - you have successfully coped with the task!

Professional advice

1. Try to collect the robot platform of plywood can be used and a small disc-shaped plastic bowl or container.
2. When choosing the wheels do not need to take too long, or your robot will go too fast.
3. If you want to improve the vacuum cleaner - attach the front two brushes, which will drive the garbage in the waste container.
4. Instead, you can use range finders bumper system, connected to the limit switch.
