How to assemble a simple robot at home. Make a robot at home yourself? Easily! Attach the battery to the motor

Today we will tell you how to make a robot from available materials. The resulting “high-tech android,” although it will be small size and is unlikely to be able to help you with housework, but will certainly amuse both children and adults.

Necessary materials

To make a robot, you don't need knowledge of nuclear physics. You can make a robot at home from ordinary materials that you always have on hand. So what we need:
  • 2 pieces of wire
  • 1 motor
  • 1 AA battery
  • 3 push pins
  • 2 pieces of foam board or similar material
  • 2-3 heads of old toothbrushes or a few paper clips

1. Attach the battery to the motor

Using a glue gun, attach a piece of foam cardboard to the motor housing. Then we glue the battery to it.

This step may seem confusing. However, to make a robot, you need to make it move. We put a small oblong piece of foam cardboard on the motor axis and secure it with a glue gun. This design will give the motor an imbalance, which will cause the robot to move.

Place a couple of drops of glue on the very end of the destabilizer, or attach some decorative element- this will add individuality to the robot and increase the amplitude of its movements.

3. Legs

Now you need to equip the robot lower limbs. If you use toothbrush heads for this, glue them to the bottom of the motor. You can use the same foam board as a layer.

The next step is to attach our two pieces of wire to the motor contacts. You can simply screw them on, but it would be even better to solder them, this will make the robot more durable.

5. Battery connection

Using a heat gun, glue the wire to one end of the battery. You can choose any of the two wires and either side of the battery - polarity does not matter in this case. If you're good at soldering, you can also use soldering instead of glue for this step.

6. Eyes

A pair of beads, which we attach with hot glue to one end of the battery, are quite suitable as the robot’s eyes. At this step, you can show your imagination and come up with appearance eye at your discretion.

How to make a robot at home so that everything works out? You need to start simple and gradually complicate it! Instructions for creating robots with your own hands at home literally flooded the Internet. The author of the article will not remain aloof from this. In general, this process can be divided into three parts: theoretical, preparatory and actual assembly. Within the framework of the article, all of them will be considered, and also described general scheme cleaner development.

Creating a robot at home

To develop from scratch, you need knowledge about current, voltage, operation various elements such as triggers, capacitors, resistors, transistors. You should also learn how to solder all this on circuits and use connecting wires. It is necessary to work out every aspect of movement and execution of actions, achieving maximum detail in actions to achieve your goal. And this knowledge is necessary if you are really interested in how to make a robot at home, and not just idle curiosity.

Preparatory processes

Before you start figuring out how to make a robot at home, you need to take good care of the conditions in which it will be assembled. First you need to prepare a workplace where the desired device will be created. It is necessary to place the structure itself and its constituent parts somewhere. The question should also be considered convenient placement soldering iron, rosin and solder. Workplace should be optimized as much as possible so that it provides convenience when interacting with the structure.

Assembly

It is necessary to think over the “backbone” of the structure on which everything will be built. Usually one part is selected, and all the others are soldered to it. Speaking about the quality of soldering, it should be said that the places where it will be carried out must be cleaned. Also, depending on the thickness of the wires and legs used, it is necessary to select a sufficient amount of solder so that the elements do not fall off during operation. To simplify signal transmission processes and prevent the possibility of a short circuit, it can be etched. Then all the necessary elements are applied to it, the resulting structure is connected to a power source and, if necessary, the device is modified.

Simple robot

How to make something easy at home? And also useful? You must keep your home clean and this process it is desirable to automate. Of course, it is difficult to create a full-fledged cleaning robot, but a minimal design that will ensure the collection of dust from the floors of rooms is quite possible. To be honest, we will consider one that works in one place and at the same time removes small debris located in the dislocation zone. To create such a design, you must have the following materials:

  1. Plastic plate.
  2. Three small brushes that are used to clean shoes or floors.
  3. Two fans that can be taken from outdated computers.
  4. 9V battery and connector for it.
  5. A tie or clamps that can snap themselves into place.
  6. Bolts and nuts.

Drill holes for the brushes at equal distances. Attach them. It is desirable that all brushes are placed at an equal distance from the others and the center of the plate. Using bolts and nuts, an adjusting fastener should be attached to each of them, and they themselves are fixed with their help. The adjusting fastener sliders should be set to the middle position. We will use fans for movement. We connect them to the battery and place them in parallel so that they ensure the robot rotates in a circle. This design will be used as a vibration motor. Throw on the terminals and the structure is ready for use. If the robot moves to the side during the cleaning process, work with the adjustment fasteners. The design presented in the article does not require significant financial costs or skills and experience. When creating the robot we used inexpensive materials, obtaining which is not a significant problem. If you want to complicate the design and make it move purposefully, you will need improvements in the form of additional motors and microcontrollers. Here's how to make a robot at home. Just think how much you can improve here! The widest field for design activities.

I decided to smoothly transition to dynamic moving models. This is a small project homemade robot on IR control, assembled from simple and readily available parts. It is based on two microcontrollers. Transmission from the remote control is provided PIC12F675, and the receiving part for the motor controller is implemented on PIC12F629.

Robot circuit on a microcontroller

Everything went smoothly with the digital part, the only problem was in the “propulsion system” - small gearboxes, which are very problematic to make at home, so I had to develop the idea " vibrobugs"The micromotors are controlled through amplifying transistor switches on the BC337. They are replaceable with any other small npn transistors with a collector current of 0.5 A.

The dimensions turned out to be very small - in the photo there is a comparison of it with a coin and another nearby matchbox. The robot's eyes are made of super-bright LEDs, tucked into a housing of small electrolytic capacitors.

Discuss the article SMALL HOMEMADE ROBOT

Electronics lovers and people interested in robotics do not miss the opportunity to independently design a simple or complex robot, enjoy the assembly process itself and the result.

You don’t always have the time or desire to clean the house, but... modern technology allow you to create cleaning robots. These include a robotic vacuum cleaner that travels around rooms for hours and collects dust.

Where to start if you want to create a robot with your own hands? Of course, the first robots should be easy to create. The robot that will be discussed in today’s article will not take much time and does not require special skills.

Continuing the theme of creating robots with your own hands, I suggest trying to make a dancing robot from improvised materials. To create a robot with your own hands you will need simple materials, which can probably be found in almost every home.

The variety of robots is not limited to the specific patterns by which these robots are created. People always come up with original interesting ideas how to make a robot. Some create static sculptures of robots, others create dynamic sculptures of robots, which is what we will discuss in today's article.

Anyone can make a robot with their own hands, even a child. The robot, which will be described below, is easy to create and does not require much time. I’ll try to describe the stages of creating a robot with my own hands.

Sometimes ideas for creating a robot come completely unexpectedly. If you think about how to make a robot move using improvised means, the thought of batteries comes to mind. But what if everything is much simpler and more accessible? Let's try to make a robot with our own hands using mobile phone as the main part. To create a vibration robot with your own hands, you will need the following materials.

Nowadays, few people remember, unfortunately, that in 2005 there were the Chemical Brothers and they had a wonderful video - Believe, where a robotic hand chased the hero of the video around the city.

Then I had a dream. Unrealistic at that time, because I didn’t have the slightest idea about electronics. But I wanted to believe - believe. 10 years have passed, and just yesterday I managed to assemble my own robotic arm for the first time, put it into operation, then break it, fix it, and put it back into operation, and along the way, find friends and gain confidence in my own abilities.

Attention, there are spoilers below the cut!

It all started with (hello, Master Keith, and thank you for allowing me to write on your blog!), which was almost immediately found and selected after this article on Habré. The website says that even an 8-year-old child can assemble a robot - why am I any worse? I'm just trying my hand at it in the same way.

At first there was paranoia

As a true paranoid, I will immediately express the concerns that I initially had regarding the designer. In my childhood, first there were good Soviet designers, then Chinese toys that crumbled in my hands... and then my childhood ended :(

Therefore, from what remained in the memory of toys was:

  • Will the plastic break and crumble in your hands?
  • Will the parts fit loosely?
  • Will the set not contain all the parts?
  • Will the assembled structure be fragile and short-lived?
And finally, a lesson that was learned from Soviet designers:
  • Some parts will have to be finished with a file.
  • And some of the parts simply won’t be in the set
  • And another part will not work initially, it will have to be changed
What can I say now: not in vain in my favorite video Believe main character sees fears where there are none. None of the fears came true: there were exactly as many details as needed, they all fit together, in my opinion - perfectly, which greatly lifted the mood as the work progressed.

The details of the designer not only fit together perfectly, but also the fact that the details are almost impossible to confuse. True, with German pedantry, the creators set aside exactly as many screws as needed, therefore, it is undesirable to lose screws on the floor or confuse “which goes where” when assembling the robot.

Specifications:

Length: 228 mm
Height: 380 mm
Width: 160 mm
Assembly weight: 658 gr.

Nutrition: 4 D batteries
Weight of objects lifted: up to 100 g

Mobility:
Capture mechanism: 0-1,77""
Wrist movement: within 120 degrees
Elbow movement: within 300 degrees
Shoulder movement: within 180 degrees
Rotation on the platform: within 270 degrees

You will need:

  • extra long pliers (you can't do without them)
  • side cutters (can be replaced with a paper knife, scissors)
  • crosshead screwdriver
  • 4 D batteries

Important! About small details

Speaking of “cogs”. If you have encountered a similar problem and know how to make the assembly even more convenient, welcome to the comments. For now, I'll share my experience.

Bolts and screws that are identical in function but different in length are clearly stated in the instructions, for example, on medium photo below we see bolts P11 and P13. Or maybe P14 - well, that is, again, I'm confusing them again. =)

You can distinguish them: the instructions indicate which one is how many millimeters. But, firstly, you won’t sit with a caliper (especially if you are 8 years old and/or you simply don’t have one), and, secondly, in the end you can only distinguish them if you put them next to each other, which may not happen right away came to mind (didn't occur to me, hehe).

Therefore, I’ll warn you in advance if you decide to build this or a similar robot yourself, here’s a hint:

  • or take a closer look at the fastening elements in advance;
  • or buy yourself more small screws, self-tapping screws and bolts so as not to worry.

Also, never throw anything away until you have finished assembling. In the bottom photo in the middle, between two parts from the body of the robot’s “head” there is a small ring that almost went into the trash along with other “scraps”. And this, by the way, is a holder for an LED flashlight in the “head” of the gripping mechanism.

Build process

The robot comes with instructions without unnecessary words - only images and clearly cataloged and labeled parts.

The parts are quite easy to bite off and do not require cleaning, but I liked the idea of ​​processing each part with a cardboard knife and scissors, although this is not necessary.

The build begins with four of the five included motors, which are a real pleasure to assemble: I just love gear mechanisms.

We found the motors neatly packaged and “sticking” to each other - get ready to answer the child’s question about why commutator motors are magnetic (you can immediately in the comments! :)

Important: in 3 out of 5 motor housings you need recess the nuts on the sides- in the future we will place the bodies on them when assembling the arm. Side nuts are not needed only in the motor, which will form the basis of the platform, but in order not to remember later which body goes where, it is better to bury the nuts in each of the four yellow bodies at once. Only for this operation you will need pliers; they will not be needed later.

After about 30-40 minutes, each of the 4 motors was equipped with its own gear mechanism and housing. Putting everything together is no more difficult than putting together Kinder Surprise in childhood, only much more interesting. Question for care based on the photo above: three of the four output gears are black, where is the white one? Blue and black wires should come out of its body. It’s all in the instructions, but I think it’s worth paying attention to it again.

After you have all the motors in your hands, except for the “head” one, you will begin assembling the platform on which our robot will stand. It was at this stage that I realized that I had to be more thoughtful with screws and screws: as you can see in the photo above, I didn’t have enough two screws for fastening the motors together using the side nuts - they were already screwed into the depth of the already assembled platform. I had to improvise.

When the platform and main part of the arm are assembled, the instructions will prompt you to proceed to assembling the gripping mechanism, where it is complete small parts and moving parts - the most interesting!

But, I must say that this is where the spoilers will end and the video will begin, since I had to go to a meeting with a friend and had to take the robot with me, which I couldn’t finish in time.

How to become the life of the party with the help of a robot

Easily! When we continued assembling together, it became clear: to assemble the robot yourself - Very Nice. Working on a design together is doubly pleasant. Therefore, I can confidently recommend this set for those who do not want to sit in a cafe having boring conversations, but want to see friends and have a good time. Moreover, it seems to me that team building with such a set - for example, assembly by two teams, for speed - is almost a win-win option.

The robot came to life in our hands as soon as we finished assembling it. Unfortunately, I cannot convey our delight to you in words, but I think many here will understand me. When a structure that you assembled yourself suddenly begins to live a full life - it’s a thrill!

We realized that we were terribly hungry and went to eat. It wasn't far to go, so we carried the robot in our hands. And then another pleasant surprise awaited us: robotics is not only exciting. It also brings people closer together. As soon as we sat down at the table, we were surrounded by people who wanted to get to know the robot and build one for themselves. Most of all, the kids liked to greet the robot “by the tentacles,” because it really behaves like it’s alive, and, first of all, it’s a hand! In a word, the basic principles of animatronics were mastered intuitively by users. This is what it looked like:

Troubleshooting

Upon returning home, an unpleasant surprise awaited me, and it’s good that it happened before the publication of this review, because now we’ll immediately discuss troubleshooting.

Having decided to try to move the arm through the maximum amplitude, we managed to achieve a characteristic crackling sound and failure of the functionality of the motor mechanism in the elbow. At first it upset me: well, new toy, just assembled - and no longer works.

But then it dawned on me: if you just collected it yourself, what was the point? =) I know very well the set of gears inside the case, and to understand whether the motor itself is broken, or whether the case was simply not secured well enough, you can load it without removing the motor from the board and see if the clicking continues.

This is where I managed to feel hereby robo-master!

Having carefully disassembled the “elbow joint”, it was possible to determine that without load the motor runs smoothly. The housing came apart, one of the screws fell inside (because it was magnetized by the motor), and if we had continued operation, the gears would have been damaged - when disassembled, a characteristic “powder” of worn-out plastic was found on them.

It is very convenient that the robot did not have to be disassembled entirely. And it’s really cool that the breakdown occurred due to not entirely accurate assembly in this place, and not due to some factory difficulties: they were not found in my kit at all.

Advice: For the first time after assembly, keep a screwdriver and pliers at hand - they may come in handy.

What can be taught thanks to this set?

Self confidence!

Not only did I find common topics to communicate with complete strangers, but I also managed to not only assemble, but also repair the toy on my own! This means I have no doubt: everything will always be ok with my robot. And this is a very pleasant feeling when it comes to your favorite things.

We live in a world where we are terribly dependent on sellers, suppliers, service employees and the availability of free time and money. If you know how to do almost nothing, you will have to pay for everything, and most likely overpay. The ability to fix a toy yourself, because you know how every part of it works, is priceless. Let the child have such self-confidence.

Results

What I liked:
  • The robot, assembled according to the instructions, did not require debugging and started immediately
  • The details are almost impossible to confuse
  • Strict cataloging and availability of parts
  • Instructions you don't need to read (images only)
  • Absence of significant backlashes and gaps in structures
  • Ease of assembly
  • Ease of prevention and repair
  • Last but not least: you assemble your toy yourself, Filipino children don’t work for you
What else do you need:
  • More fasteners, in stock
  • Parts and spare parts for it so that they can be replaced if necessary
  • More robots, different and complex
  • Ideas on what can be improved/added/removed - in short, the game doesn’t end with assembly! I really want it to continue!
Verdict:

Assembling a robot from this construction set is no more difficult than a puzzle or Kinder Surprise, only the result is much larger and caused a storm of emotions in us and those around us. Great set, thanks
