The inner world of the iRobot Roomba 555 robot vacuum cleaner
Hello! I have heard many times how beautifully Apple does the insides of its products, from an engineering point of view. Here on Habré not so long ago someone post disassembling a robot vacuum cleaner "one Chinese company", I do not remember which model. I want to show how beautiful the iRobot vacuum cleaners are compared to other manufacturers.
We read. Careful traffic!
Small clarification. The idea of publishing the topic came to me unexpectedly for me, during the disassembly process, when I almost completely disassembled the vacuum cleaner. because in the post I will show the assembly process.

So let's go ...
This is a brush reducer. When I opened it, everything was black and sticky ... all the gears were wrapped in hair mixed with grease. One gear even slightly undermined this very hair. As you can see, I washed and smeared everything.
This is a general view of a block of brushes with a gearbox.
Without brushes.
With brushes.
Under the brushes is a sensor, the purpose of which is incomprehensible to me.
It looks like a speaker from Chinese postcards, but here is a whole fee for its work.
It is installed in the case.
Tax, block with brushes assembled.
Now we begin to collect the vacuum itself. To begin, install the motherboard in the case.
Fee from the top side.
Apparently, the manufacturer uses one type of board for the entire line of vacuum cleaners, soldering additional electronic components depending on the functionality.
She's from the bottom.
The processes here are installed, judging by the inscriptions on the case, ARM. Unfortunately, I only looked at the captured photos when I had completely assembled the vacuum cleaner. Because the inability to read the markings noticed late. I apologize for this.
Well, let's continue to collect. To begin with, we will install a metal screen in place, which, apparently, protects the control electronics from interference from the vacuum cleaner engines.
This is the reverse side of the empty case.
This is a frame with infrared sensors that are installed behind the bumper of the vacuum cleaner.
Here are close-up sensors. They are actually more along the entire length of the frame.
We connect all sensors and motors to the motherboard.
We fasten the board to the case.
Install the unit with buttons and indicators.
Close the cover plate with the designations of the indicators.
Cover it with a decorative / protective cover.
Here I have already closed the case and installed the bumper. The process is not difficult, nothing interesting.
Taxes, now we establish working mechanisms.
Let's start with the propeller brush motor.
Install. We screw on.
Now the module of the right wheel.
Next block brushes.
Installed.
Well, finally the battery. She is pretty big here. With comfortable straps for taking out.
By the way, she is here Nickel Metal Hydride. 3000 mAh
The bottom side of the battery with the contact pad.
Put.
It remains to close all the lid.
By the way, the rotation of the front wheel is also controlled by the sensor. If there is no rotation, then we are stuck and we need to start measures to get out of this situation.
Install the front wheel unit.
It is simply inserted and snaps into place.
Well, the wheel itself. By the way, it is in different colors for the sensor.
Fasten the brush-propeller.
Made by
It remains to install a garbage container.
Is done.
So I collected a full vacuum cleaner.
On the motherboard there is a port similar to PS / 2. Most likely for flashing the vacuum cleaner. I would like to know from the readers, can anyone do this with his vacuum cleaner?
For the quality of the photos I apologize, I photograph almost the first time in my life. And besides, on the phone. =)
I hope my post was interesting to someone.
Thanks for attention!
