Does anyone know about the operating system of fanuc robot？

It's likely it's something custom, though parts of it seem to be at least inspired by DOS (uses FAT(16), similar commands in KCL/CM/COM files, etc).

ROS is the name that Fanuc uses for its OS as far as I know.

Do not confuse that with the open-source ROS.

It's a type of Windows OS.

If I recall correctly, I saw a FANUC brochure telling their OS is Unix based.

They used this as a selling point, since "if it is not Windows, it can't get viruses", or something like this.

The TP is running Windows CE, yes. The controller, no (or at least: not that I can determine).

I was under that assumption, because I heard in the past it was a custom OS Fanuc developed. The other day I discovered the TP ran on Windows, but wasn't sure if it was the whole system or just the TP. Thanks for the information.

I doubt viruses are the biggest problem for a Fanuc controller, seeing as fragile as they are.

rf103, well I haven't seen a better controller in a long time...

I'm not talking about the user experience, that is fine

Once you get to know the internals a bit, it seems to be not too hard to get it to do unexpected or strange things, or just crash. That was what I was referring to.

yep, and that's how I understood that. Is there any robot maker, who has totally idiot-proof controllers? I don't think so... If you don't do what you are not sure of, then you'll be just fine - that is true not only for Fanuc.
What I like about Fanuc controllers is that even if you don't feel confident with what you are doing, you can always make a backup and restore it quite easily if you mess things up - it covers most issues, you'll have to be quite stubborn and careless to actually make the controller totally inoperable.

I've found the brochure. In fact, they didn't mention Windows. The only say R-30iA isn't "PC-Based.

Yes, that makes more sense.

It's not PC-based allright. Writing something virus-like would not be too difficult though.

But I guess the idea is that an R-30iA cannot pick up a Windows-based virus.

In fact, the virus-free quote is there.

I think they didn't mentioned Windows to avoid a lawsuit.

But I think this specific line was a provocation to KUKA.

Unix-based seems likely. Fanuc ls and Karel source files use "LF" line ending rather than "CRLF" which would be expected from something DOS based.

All evidence points to a custom OS, or derivative of an old embedded OS.

I would not expect any unix or windows heritage.

Knows someone what is the cpu architecture runs operating system of fanuc controllers ?

Controller cards have bga chips with fanuc labels.

Operating system is some realtime os and windows are not realtime

so windows ce are only for TP not for OS.

Also controllers have very low memory so only something lite unix - linux

can operate on so low memory.

linux with realtime kernel exists only the recent years so i suppose there is not realtime linux

but some old unix OS with realtime kernel.

Maybe is something of these

Comparison of real-time operating systems - Wikipedia

I have opened IMAGE backup *.img file with peazip v9.4

When do backup image file is split to chunks and must be

merged these chunks to extract image file

this can be done with command copy /b FROM *.IMG BACKUP.IMG

and after you create BACKUP.IMG can you extract it with peazip.

Exploring the files seems that runs windows embedded compact for arm

that has real time kernel. FAT16 filesystem.

I believe Windows runs on iPendant, not on controller CPU.

All are windows ce because filesystem is FAT16 on system

EOL in all text files is CRLF (this means windows not linux-unix).

Drive names are with letters (not mount paths) and file path with inverse slash (\).

Also controller has full tcp/ip stack and functions that only full operating systems offer

like windows-linux-unix (NOT dos).

Windows CE has realtime versions (with realtime kernel).

All evidence seems that all are windows embedded arm architecture (pendant and controller) .

Advertisement say not PC based (means not x86/x64 based) doesn't say not windows based.

I will investigate more but am almost sure that OS is windows embedded (realtime).

The german support told me that the controller runs a home brew based on a *NIX system.

The tablet TP runs on Android.
