Maybe they are doing you a favor by stealing the headaches this thing can bring. The Mammotion Luba seriously sucks!!!! It is Chinese so..... I probably wouldn't have purchased it if I knew it was Chinese. I have always had bad experiences with Chinese Products. They never perform as stated by the company. They seem to always be about image but have no substance. I purchased one of these a year ago and it was difficult to set up but I eventually got it. There were many issues with this thing but I managed to work around them. Tech support was almost non existent. The only place to get support is chatting through their app and that is buggy and constantly loses connection. You have to wait for a tech to answer because they are constantly "experiencing a high volume of inquiries" and you have to wait in a queue that tells you your position in that queue. The queue can magically grow and your position moves backwards (like from 2 to 14). Once you get the chat with a tech, you can magically get disconnected when the suggested fixes don't fix anything and the problem proves the be more difficult than a restart. I figured maybe it was just new stuff and should get better with time and updates. Yeah right!! This was the situation when I purchased the unit a year ago. Now with all their upgrades it actually seems to have gotten worse. Now their GPS location system seems to vary by more than a foot and as much as two feet. In places where I had spotty location info a year ago now have no location fix at all. And yet they still have 22 to 27 co view of the satellites. The RTX is viewing the entire sky and sees 39-40 satellites. So if they can't get by with 50% or more co viewed satellites, the tech must be flawed. And don't get me started on the app. You have to use the phone app to do everything with this robot. The app started out clunky and just got retarded with each update. Side Note: This thing keeps an open connection to a Chinese server. A high security risk to have with a country that has vowed to hack the USA. This is a great idea but the execution is abysmal. It isn't getting better either; it just keeps getting worse. I don't know how to express my dissatisfaction with this product any better without starting to use bad language. So I'll stop here. Bottom line: If you want more headaches in your life, switch from manual mowing to this piece of crap robot!!!! P.S. Watch out when comments are turned off of Luba review videos.

The 2 mowers running different firmware. Not exactly comparable

Hello, so is it possible to still get ot through the kickstarter? Thx

Awesome test! Some quick questions: 1) I have a Luba 1 and have tons of issues because of canopy coverage, but with RTK on roof I get about 28 satellites. Does the new RTK on Yuka have an advantage over the older Luba RTK? 2) I have a hill/slope that is around 24-28 degrees (Luba 1 no issues). I heard Yuka has a sensor that will go off at 24 degrees. I remember you did an original Luba 1 hill test, have you been able to do the same with Yuka? I don't want to get Yuka and it can't mow my hill.

Cool how the color scale dynamically adjusts.

My phone can't even pinpoint where I am.

Class

Your pup is so cool, well warm, well orange.. you know what I mean.. 😆

So it is $250 and there is currently a $30 coupon. And when I searched for the Flir E4 that someone mentioned, well, $220 doesn't seem so bad. Much like you, I might have to wait a little before pulling the proverbial trigger. But thank you for the info.

On my Flir E4 thermal imaging camera, when it first starts up the camera is not precisely accurate until the IR sensor has "warmed up" / completed enough calibrations, each time the camera stutters it's doing a re-calibration. I expect the TopDon is doing the same.

really cool. thanks for sharing

Here in the UK I've seen people use those to see where the heat is getting out on their houses - presumably you would use it for the opposite reason!

I have a handheld stand-alone thermal imager. It’s fantastic for diagnosing Air Conditioning issues and keeping contractors honest. It’s a great thing to keep around. I’ve loaned it out to friends and coworkers multiple times for AC work.

you should have watched my review before buying it.

I noticed when you were working on Luba, the rubber boots that are located above. The rotating cutting blades had big tears in them. Was this from low quality material or you being rough also, how about we have a replacement video because I think it’s low quality material and all of us owners are going to need to replace those rubber boots.

Hey CP, can you show us how Yuka works with Google Home?

Mine is getting stuck, we connected it today and cannot get the lectron adapter off

Thanks a lot for your video, I was so stressed about my positioning problems, now I'll try to put the RTK on the roof or on the lawn, but I don't have electricity in the garden. Definitely going to do it !! :)

Is it true Mammotion foolishly deprogrammed the green LED in the RTK?

BUYER BEWARE!! I have had Mammotion's Luba for over a year and it is total crap. It runs into the house, runs over flower beds, jams itself under the firepit and car, etc etc. It has the scars to prove it. What is more attrocious though is their customer support. It is non-existent. It took me over a year to convince them that there was something wrong with it. Finally this "Oh maybe you have a motherboard with one of the bad chips" right in the peak grass cutting season here. You have to send it in to get it fixed. They will not send you a loaner. They will not give you a performance guarantee where they pay a penalty for every day it is gone past a certain amount of time. They will not use "same day shipping" even though they promissed they would. They promissed it back in two weeks, it took two months. When it left, it was pissing me off but it would eventually get the job done with a whole lot of swearing. They shipped me back a brick. It no longer works at all. I have spent well over a hundred hours with them in chat along with writing emails to try and get it replaced as it is still on warranty. All the while now having to pay someone to cut my grass. I am hoping to kick off a class action lawsuit.

Would like to see a Yarbo comparison verses Yuka and Luba

It could be that you were right the first time, and that all of these issues lately are caused by Mammotion software regressions / bugs. Since the EU 868 MHz troubles started, they have been trying to rework all of the RTK code, and it has gone TERRIBLY. You are not the only one having problem with slight tree cover of the RTK station, where no such troubles used to be present with earlier software / firmware versions. Don't get me wrong. It is important to have good placement of the RTK station, but what you are seeing here doesn't really make 100% sense.

Honestly, you lucked out not needing to contact customer support; they are a nightmare. My Luba 2 showed up in April, not charging correctly right out of the box. It took until the end of May for them to agree to send it back for repair. It was a three-week turnaround, only to still have the same issue. I have contacted them multiple times since receiving it back, only to get the same line of crap that they are sorry and understand how frustrating it is. But then tech support never contacts you like customer support claims they will. I even asked for a replacement robot, to which they said no. Once you spend the money on the robot, they could care less about you. So consider yourself lucky that it was an easy fix for you.

Can you get out of spot mode by just clicking on the word spot mode and change it there?

Great video! Thanks for posting these helpful videos about the Yuka. It's been great! Couple questions: 1. Have you noticed any improvements since the new firmware upgrades were released yesterday? 2. The RTK is now getting better view of the sky, but did moving the RTK farther away have any negative impact on reaching the Yuka? Does that signal to the robot have good reach, even through a house, etc? 3. Maybe you can post a video about your favorite settings for the Yuka? I'd like the get better striping patterns in my lawn. Perhaps wider cutting spacing will help? I'm also optimistic that the bagger attachment will help stripe since it brushes the grass.

Was this before or after the recent firmware upgrade?

Ok, it looks like I am on the hunt for a treeless area. I don’t really have one. I need one of your “other” robots. 😊. New job for tomorrow.

And the house was also very near to the RTK…

Yes I set my to the top of the roof. Now it works perfectly!

Very very good, RTK is key of the whole proces, ❤

Nice job, I know what you demonstrated is true. However, as much as you don't think the attic is a good idea, plenty of people just don't have wide open spaces to install the RTK antenna. I just got a Sunseeker Orion this weekend, and had a few issues with satellites. I finally installed in the attic and my signal is always strong. So now, there are almost no drop-outs on the mower end at all. And nothing the mower has not overcome. The only potential problem I can envision is the heat up there. But I'm monitoring it, and so far it doesn't seem too outrageous. Time will tell. I don't know how many satellites I'm seeing, because the sorely lacking app doesn't provide that info. I would have liked to install on my roof, but it's a bit too treacherous and I also have hardiplank. So I'm not that motivated to secure an antenna to it. Not like wood at all. Anyway, while it may not be preferred, the attic placement seems to work well and it might be the only viable solution for many. Thanks for the video, I think I've seen all of yours. Appreciate it!

The reason it performs so much better is because the rtk algorithm is designed for accounting for atmospheric correction. It assumes that the atmospheric error is the same for yuka and the rtk. Tree cover also causes distortion, so the rtk is trying to correct for the tree cover too, but the distortion yuka is experiencing is different to the rtk. It can't be said often enough but the rtk must have open sky. No attics, no trees, no porches

Wow, you must be dedicated. Losing all your maps in the name of science. Just one more comment, the RTK is looking for the entire sky, not just up above, so being near a fence, a wall, or anything else that blocks the horizon can be as bad as a bunch of leaves overhead. Thanks for sharing.

First time lapse is 23 minutes of mostly outside that little "forest", it switches 6 times to vision when it comes near the trees and turns around. Second time lapse the status bar on top is cropped out... so no information how it really performed under more tree covered area. The best of RTK placements can't amend a GPS module on the mower that can't find satellites, RTK navigation needs both.

I wonder if an update helped too?

Do you think maybe you were getting multi-path distortion because the signals from the RTK to the Yuka was bouncing oddly off of all those rings and poles of the tomato plant cage right next to the RTK (as well as the brick wall of the house)?

No flowers were harmed in the making of this video 🥀🌻 😁😁

Thanks for the video. I'm sure I'll be sharing this a lot, as it helps explain many of the positioning problems people share on Facebook and Reddit. I'm sure it'll help save quite a bit of frustration for those who have been having issues!
