In short I’m an IT guy with a background in satellite and microwave communications, so it’s very possible I’m over thinking this.

On the RTK reference station I see what I assume is a 2.4 ish GHz antenna for the reference station to talk to the robot. The remaining portion of the unit I assume is a GPS antenna IE the multiple callouts for unobstructed view, avoid L shaped corners etc in the manual. With that said my question is about the robot itself.

Does it have to be connected to WiFi the entire time? Reason I ask is the area he is looking to mow doesn’t have WiFi signal.

In short I own a 60+ year old home with the original bilco doors. The doors and outer frame are starting to rust out. That and the stairs and such are in terrible shape. It should all be ripped out and redone.

20 years ago we had egress window inserts put in to be legal for basement bedrooms with sump pump inserts etc. Does such a thing exist for basement stairs with bilco provisions?

I’m an IT guy, most specifically a network engineer. Anyways this is kinda a different question but IT affiliated in a way.  I’m looking for a tool (either Windows or Linux) that will hash every file in whatever the specified path is and look for hash duplicates.  Kinda an uncommon request but the reason is below. 

My mom passed away last month, and my brother and I are in the process of clearing the estate (we are co-executors). One of the things I’m doing is going through her computer and getting all the family photos and anything else important off it. That’s kinda my defacto job being I’m the IT guy in the family. 

The problem I identified after about 10 minutes of looking into this is there is a TON of removable media she copied stuff onto. I’m talking about 3x dozen SD cards I’ve run across and about the same for thumb drives, various CDs that have been burned, and an external hard drive. All are LOADED with family pictures, but that’s not the only thing on the media. There have been other important things (like insurance) that I had no idea about. So I can’t just toss it. In some ways it’s becoming a forensic dive. 

Im guessing there is close to 500 GB between all the media.  I’ve already noticed a bunch of duplicate XLS and JPG documents/files just by skimming it.  So I’m certain there are ALOT of other duplicates. So if there is a tool that can compare hashes of files in batch and list any that are duplicate by my thinking is probably the best way to eliminate at least the bulk of what I need to dive into.  MD5 should be perfectly adequate for this. I still need to go through everything manually, but if I can parse down what I need to go through that would help. 

Note:  Can’t use file names because just in my brief digging I’ve found instances of her copying files and renaming it. I also have found instances of her saving a file like 10x times as a new file. IE myfile.txt and myfile(1).txt, myfile(2).txt, and so on.
