Monitored the market for the purchase of a second-hand (probably broken) robot vacuum cleaner for further experiments with its hull but with its own MK.
I bought a used iRobot Roomba 4230, a complete set, even with a box, but without instructions. It was sold as firewood, marked with spare parts. According to the seller: works, but every 5 minutes stops with an error, if you press the button, it will continue to work, (again for 5 minutes), and so endlessly. After the home tests, the seller's words were confirmed.
Googled, conducted self-tests as described here: http://www.irobots.biz/index.php?show_aux_page=5.
As a result, lucky, he earned as follows:. Or not, because the subject for experiments now have to look for a new one. The reason was a strong clogging of the brush reducer, which led to heavy rotation, the robot gave an error ...
The former owner has a cat, and he did not completely clean his campaign for a year.
The battery holds exactly 40 minutes, perhaps an hour, from end to end has not yet been tested.
Judging by the numerous reviews and videos (such as http://robocraft.ru/blog/news/211.html), it should be carefully disassembled and cleaned, hair can be absolutely everywhere. This incl. Leads to a deterioration in the rotation of the reducers and, as a consequence, a faster discharge of the battery.
What did I want to ask, if I was going to disassemble it, I needed something to sfotkat or measure it inside the structure, mechanics? In general, everything there is very similar to the numerous materials posted on the Internet, there is nothing new like.
The battery while I will train or look for a replacement, according to the former owner, he lay half a year in the closet with the battery not disconnected.
The battery is clearly fooled, when discharged, it must turn off the brushes with a turbine and start looking for a base for recharging.
And I get it this way: he plows 40 minutes showing full charge, then the discharge indicator sharply shows the full discharge, the robot starts to rush about in search of the base, usually not finding it next to a screaming cry for help falling asleep
