00:00:02

has become extinct,

00:00:05

what will people leave behind today,

00:00:13

our life is completely dependent on

00:00:15

electronic devices, well, how much

00:00:17

electronic devices depend on us,

00:00:19

even the most modern robots need the

00:00:22

constant presence of a person and

00:00:24

maintenance, I will try to

00:00:26

create my own robot from scrap

00:00:27

materials and find out how long he can

00:00:30

last without my help the

00:00:50

robot must survive autonomously for years

00:00:52

he should not be afraid of water and snow and

00:00:55

other external influences, he

00:00:57

must also collect energy himself how to

00:00:59

charge the battery in the absence of sockets

00:01:01

I decided to use the energy of the sun,

00:01:03

namely solar panels

00:01:06

to convert solar energy I I will be

00:01:09

using these

00:01:10

polycrystalline solar panels,

00:01:12

how do solar panels work, how do solar panels

00:01:14

work, just look, if you put a

00:01:17

black stone under the sun's rays, it will

00:01:19

quickly heat up; a solar battery is the

00:01:22

same stone; it's just that solar energy

00:01:24

is converted not into heating, but into

00:01:26

electricity;

00:01:27

my choice fell on hard

00:01:29

polycrystalline silicon solar

00:01:31

batteries their efficiency is lower than that of

00:01:33

single crystals but due to

00:01:35

heterogeneity they are not so sensitive

00:01:37

to scattered and non-directional light,

00:01:40

that is, they will better tolerate

00:01:42

cloudy and cloudy weather they are quite

00:01:44

cheap the variety of their shapes is ideal

00:01:47

for design

00:01:48

we went up to the roof in this box my

00:01:51

solar panels

00:01:52

Now we’ll lay them out and see what

00:01:55

they’re capable of.

00:01:59

First, let’s check what kind of current one

00:02:01

panel gives and how much the current depends on

00:02:03

pollution. We connected one farm and

00:02:06

as we can see, its voltage dropped from 6 volts

00:02:09

to four and a half and the output current is

00:02:12

up to 250 milliamps,

00:02:14

pure water. did not affect the

00:02:16

result in any way, and when pointing the panel at the

00:02:18

sun, the voltage increased to 4 and 7 volts

00:02:21

and the current to 240 milliamps;

00:02:24

muddy rainwater and dirt reduced the

00:02:26

panel parameters to a minimum, so

00:02:28

it is better to keep them clean; for a lithium

00:02:31

battery, I decided to use a

00:02:32

simple one without charging with a maximum

00:02:35

current of 1 ampere, even

00:02:38

8 solar panels not pointed at the sun survived and

00:02:40

charging, and at most two of these companies are more than

00:02:43

enough to charge the battery of the robot,

00:02:45

and after experiments I realized that the

00:02:48

solar panel produces almost the

00:02:51

current specified by the Chinese

00:02:52

manufacturer, but this is not quite for you the

00:02:54

control electronics are quite sufficient and

00:02:56

run entirely from the battery;

00:02:59

the battery is discharged; the solar panels

00:03:02

have charged it; the electronics are again

00:03:04

connected to the battery and take

00:03:06

energy from there through the solar panels; I

00:03:08

figured it out; it’s time to deal with

00:03:10

the batteries; the battery is used; and I decided to

00:03:12

use lithium batteries; there are

00:03:14

many types of lithium

00:03:16

batteries; for me, the most important

00:03:18

parameter is the number of cycles

00:03:20

charge and discharge,

00:03:22

after all, it will depend on it

00:03:25

how long the battery will live. The most

00:03:27

durable ones are phosphate esters,

00:03:29

they are found in electric cars, in electric

00:03:32

scooters, and by the way, equipment

00:03:34

that requires a large number of

00:03:36

charge and discharge cycles of the battery

00:03:38

must be charged with a constant and

00:03:40

stable current source, how to get a

00:03:43

stable current source from solar

00:03:44

panels, because the sun can set behind

00:03:47

the clouds, dust and other factors can get out of the clouds onto the solar

00:03:49

panels, the

00:03:52

value of the current is constantly changing,

00:03:54

for this, special boards are used

00:03:56

that charge the batteries from

00:03:58

solar panels,

00:03:59

I would like to use fly iron

00:04:01

phosphate batteries, but find such

00:04:03

a board for them I couldn’t charge, so I

00:04:05

decided to use regular

00:04:07

lithium-polymer batteries and

00:04:09

this charge board, the number of

00:04:14

charge and discharge cycles of polymer

00:04:16

batteries was much lower, so I

00:04:19

had to dig around on the Internet and find a

00:04:21

battery with the highest value,

00:04:23

I found these lithium-polymer

00:04:26

batteries,

00:04:27

judging by According to the technical description, they have

00:04:30

300 charge-discharge cycles,

00:04:32

which means that even if the robot

00:04:34

charges and discharges them once a day,

00:04:37

such a battery will last for about

00:04:40

a year. I decided to use two

00:04:42

batteries, one main and one

00:04:45

spare, which duplicates everything like in aviation,

00:04:48

so the robot will work

00:04:51

from only 1 or tigo polymer cell and the

00:04:53

maximum voltage in the robot will be 3

00:04:55

7 volts. Having figured out the power supply, I decided to

00:04:58

create a 3D model of the robot.

00:05:05

I could simply lay out the panels and

00:05:08

put them somewhere on the grass or on the

00:05:11

ground, but this is not the best option

00:05:14

because they will constantly get

00:05:16

dirty, moisture and liquid will get into them,

00:05:18

eventually they will all become dirty

00:05:20

and stop generating electricity

00:05:22

completely, so I decided to hide them in a

00:05:25

box. The robot will have a unique

00:05:27

daily routine,

00:05:29

most of the time it will sleep in

00:05:32

sleep mode. You will consume a minimum of

00:05:34

energy. save it when

00:05:37

the energy is not enough

00:05:39

once a day in the morning, according to the real

00:05:42

time clock, the robot wakes up and begins to

00:05:44

take information about the sensors (

00:05:49

light sensors and rain sensors and information about the

00:05:52

battery status), then if the robot

00:05:55

is operational, it starts sending

00:05:58

data to me so that I know that it is still alive

00:06:02

functions to send data it

00:06:04

uses the telemetry standard nb comfort and the

00:06:08

mqtt data transfer protocol after the

00:06:11

data is sent and if the batteries of the

00:06:14

robot are low it begins its

00:06:17

opening cycle the robot opens and

00:06:19

straightens the solar panels and stands up for

00:06:22

charging if the batteries are

00:06:24

fully charged be in the open

00:06:26

state and we are no longer required,

00:06:28

so it sends me a signal

00:06:31

that I am charged and I fall asleep and

00:06:34

goes into sleep mode.

00:06:35

If stainless steel parts can be

00:06:38

left in the condition in which they

00:06:40

are, then

00:06:41

it is better to process raw aluminum parts

00:06:44

in a robot.

00:06:47

parts from the moment they were

00:06:49

made, they bent a hundred times,

00:06:52

got dirty and covered with an ugly

00:06:55

oxide film, so I decided to

00:06:57

paint them, I will masturbate mine

00:07:01

in this bath, I will immerse the aluminum

00:07:03

parts, here we have the slate, where did I get it,

00:07:10

ask for lead sheets, and so

00:07:12

the anode-cathode cathode Canadian that to

00:07:16

I will connect that frame to it with a minus trick, I

00:07:20

will connect

00:07:21

the wires along which the positive contact will be taken into account,

00:07:25

I will take care of the protection before it de

00:07:29

ravale, whether they need to be cleaned,

00:07:32

they can be cleaned mechanically or

00:07:34

chemically,

00:07:35

that is, etched for etching, I

00:07:38

need to create an

00:07:39

alkaline solution, I will create it from

00:07:42

distilled water and caustic

00:07:44

soda this year

00:07:51

Vitaly I etched 4 fill my bath with

00:07:55

sulfuric acid we take out the first part

00:08:03

quickly and clean it now I need to

00:08:10

connect the positive terminal

00:08:12

to the workpieces the reaction has started this can be

00:08:20

seen by the gas bubbles appearing the

00:08:24

anodizing process takes from 20 to

00:08:27

30 minutes I didn’t end up masturbating with the

00:08:37

first pancake in a lump; the part seemed to be

00:08:39

covered with an oxide film but

00:08:43

was not painted; I decided to

00:08:45

get rid of it so that there would be no accidental

00:08:47

contact; it was rotten like old bread; I made

00:08:51

denser screams and also calculated the

00:08:54

correct value of the current; let’s try again

00:08:58

[music]

00:09:01

I have no idea what happened,

00:09:04

the power supply caught fire, guys, no matter how hard I

00:09:09

tried to probe using a large

00:09:11

bathtub, nothing worked, but

00:09:14

I managed to paint them using a

00:09:17

small bathtub like this

00:09:20

[music]

00:09:45

probing is over,

00:09:48

these are the parts

00:09:49

I decided not to paint and leave the

00:09:51

natural color that is obtained on

00:09:53

aluminum after anodizing, let's move on to

00:09:55

assembly

00:09:57

[music]

00:10:02

first I assembled the sun tracking mechanism,

00:10:04

it consists of a central axis or

00:10:07

three motors mounted on it, two

00:10:10

motors control the rotation of the robot along

00:10:12

one plane and one motor in another with

00:10:15

the help of these motors and 4 light sensors,

00:10:17

the robot will accurately point the solar

00:10:20

panels directly at the sun

00:10:21

[music]

00:10:25

in addition to the sun tracking mechanism, I

00:10:28

assembled two more mechanisms for opening

00:10:30

solar panels;

00:10:31

an idea I spied on old satellites; an

00:10:35

electric motor and a screw gear

00:10:37

convert rotational motion into

00:10:39

translational motion, thereby opening the

00:10:41

solar panels

00:10:46

these are Kobi solar companies are ready, each

00:10:51

of them is planted behind their own gang, the reverse

00:10:53

mechanism and now I will connect them to the

00:10:56

tracking mechanism

00:10:58

[music]

00:11:21

Thor's hammer so that the robot moves in and out

00:11:26

of the box, I had to make another

00:11:28

mechanism, code-named elevator, the elevator

00:11:31

consists of 3 of another screw gear

00:11:34

and several guides and another

00:11:37

motor, the motor rotates the screw and moves a

00:11:40

special plate on which it is

00:11:42

fixed and the upper part of the robot and the robot in

00:11:45

this way opens and rises

00:11:49

from the box. Another important feature

00:11:52

that I decided to do is to screw the

00:11:56

legs to it because it will stand on the

00:11:59

floor and I wouldn’t want the beautiful

00:12:02

transparent body to touch the ground, even

00:12:05

though the robot currently doesn’t

00:12:08

have sensors; it already has a bunch of motors, a

00:12:11

bunch of limit switches,

00:12:13

a whole bunch of wires, that is, all this

00:12:17

must be controlled by something; the robot

00:12:20

must have a brain as a brain, I

00:12:22

decided use stm32 series l100

00:12:25

this series with ultra-low

00:12:27

power consumption arduino or other

00:12:30

boards I did not want to use here

00:12:32

because they do not have a sleep mode and

00:12:36

they have too much

00:12:38

parasitic power consumption those functions

00:12:41

that are not currently used by

00:12:43

the controller I decided to place all the control electronics

00:12:46

on one platform for

00:12:48

this I made my own boards, each payment

00:12:52

controls a certain component of the

00:12:54

robot and that's how they turned out in the

00:12:57

end there is a GSM modem rain sensors

00:13:02

boards that control the power and

00:13:04

charging of the robot motor drivers and a

00:13:09

bunch of other things to track the sun I

00:13:11

will use the classic scheme at

00:13:13

4 lux meters separated by a cross, the

00:13:17

sensor that falls the shadow gives a

00:13:19

signal to the controller about this and the controller

00:13:21

turns the solar panels in

00:13:23

the opposite direction 100

00:13:24

before connecting all the wires to the

00:13:26

control dress,

00:13:28

our lux miters should take their

00:13:30

place on the solar panels here

00:13:32

when the assembly stage has been completed and I

00:13:36

finished fiddling around in the workshop, it’s

00:13:38

time for the first field tests, I’m back

00:13:41

on the roof, this time I’ll do a couple of

00:13:42

experiments in the open air, the

00:13:44

robot is almost assembled, it’s

00:13:47

only missing the front cover, I removed it to

00:13:49

have access to the control electronics,

00:13:51

first I’ll time how long it takes it

00:13:54

will open completely,

00:13:55

then I will conduct an experiment with pointing

00:13:59

at the sun, apply power,

00:14:02

turn on the robot to open and time it

00:14:12

[music]

00:14:25

[music]

00:14:44

[music]

00:14:53

but today, all the guys, more detailed

00:14:56

information and the results of all

00:14:58

experiments will be in the article on

00:14:59

our social networks, subscribe and wait for

00:15:01

the link bye

Description:

Нас окружают роботы. Они везде — в цехах заводов и в машинах, в космосе и на полях. Мы уже не можем существовать без них, но могут ли они выжить без нас? Реальность отличается от голливудских сказок. Мы не сможем создать ВАЛЛ-И, который проживёт без техобслуживания хотя бы пару лет. Даже идеальные сферические аппараты в вакууме имеют крайне ограниченный срок службы. А что можем сделать мы, простые русские DIY-щики, без бюджета NASA и поддержки Сколково? Мы попробуем собрать робота-выживальщика, единственная цель существования которого протянуть как можно больше, без вмешательства человека. Энергетическая установка, механика, управляющая электроника — обо всём этом расскажет создатель уникального проекта, главный XOD-ер планеты, Макс. Просто Макс.
