Luba 2 Working with No Satelite Signal - Wireless Robot Lawn Mowers Australia 

Yes it is promising. We will still do more testing on areas that have low GNSS signal strength so we can get a better understanding of when Luba 2 will use this camera positioning vs its traditional RTK positioning.

Habe voll die Enttäuschung erlebt,er ist nicht so zuverlässig wie es von Mammotion gepriesen wird,erlebe es gerade

Thanks. yes you are correct. Active edge detection would be great. Segway I series has a similar feature and it works ok, but certainly not perfect yet. A few more FW updates and hopefully LUBA 2 will have this feature too.

Hopefully it does. We posted another video on this today - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-__eXamnCdaI.html

Thanks. Yes I will be testing the base station location far more thoroughly in coming videos. also testing in low GNSS signal areas as I feel this is the biggest issue currently with LUBA 2. Getting that smooth transition between using satellites to using the camera and IMU is something I hope that gets better over time with new FW updates.

So my Luba 2 has arrived and I successfully moved the charging station to my basement garage. Luba was then sent out to mow and was able to return to the charging station (provided the garage light was on). When light was off it stopped a few feet in. I'm assuming this was due to insufficient daylight from just the open garage doorway. However just a few minutes later it would not leave the charging station (saying robot not ready) unless manually controlled by bluetooth back outside to calibrate satellite positioning. By the way I have a 4G sim and can access it remotely through this and view through its camera, can even select mow but it says "not ready". We're tantalisingly close. Hopefully Mammotion could get us there with a software update to retain the capabilities that it is already desplaying, until the next mow. I don't want to leave it outside and the garage has perfect constant conditions for a long battery life.

I havent been approached by Dreame as yet. But im sure we will deal with them at some pint in the near future.

I saw a comparison on RU-vid between Luba 2, Dreame A1, and another lawnmower. The Dreame navigated very well, and impressed me, but the complaints were that it had trouble in tall grass (something like 3" or higher) and due to the front wheel just being a loose wheel (like an office chair caster), the unit got bounced around on bumpy grass and sometimes went a little off course.

You can't move the RTK antenna once it's mapped. You can only move the charging station. If you want to move the RTK, the whole mapping needs to be done again.

It is the same as any RTK based robot. If you move the RTK Base Antenna you will move the mapping as well. So as soon as you move the antenna you will need ot remap everything.

Im pretty sure the IMU will take over and it will still find its way as long as the obstacles dont force the robot to move more than 0.5mt from the centre line of the channel. I will be doing more testing on this in future vidoes as the position of lube with no satilite coverage does expire in a short period and then Luba is not able to travel again until it has its Satellite position again.

The ultra sonic sensors ar eonly used for object detection. So both will mow much the same as each other at night. If you have open areas to mow then Luba 1 will do the job well. If you need the camera detection for low GNSS signal areas then I would buy Luba 2.

Just travel very very slow and it reduces the cahnce of it happening. I am going to more testing of this in future videos.

Hi, just go into your map. Click edit and you should see a list of your areas. At the bottom of each listing there is a little arrow pointing down. Click on this and you will see a list of no go zones and channels that are related to that area. You can then selct the channel you want to delete and then press the trash can icon to the right of it.

I wish I could answer this better for you, but you are right the cost of the bigger battery would be insignificant. It is just marketing, they make low profit on the smaller models and high profit on the larger models.

Hi, we are currently running 1.11.511.381.

Thank you greatly for letting me know this. It may be due to a recalibration of the IMU. I will see if I can get the actual reason for this from Mammotion and find out if future updates might allow this to work.

I have contacted some of the Mammotion techs that I deal with and they have clarified to me today that the only reason for Luba 2 to not return to work after being on the charger over night in a non GNSS charging position would be due to low light conditions. The timer that resets the robots position after an hour or two in areas with no GNSS signal does not apply when it is on the charger. I will test this again in a specific video for just this function, but I won't be able to do this for another couple of weeks. If anyone has tested this with the latest FW, please comment and let us all know your findings.

@@robotlawnmowersaustralia7913 I'm on the latest beta firmware. I have a light in my backyard, i could leave it on tonight and see what happens. But I do not get the notification anymore that says "ambient light too weak, turning off camera..."(Paraphrase). I have not found out if everyone on beta has this same experience. Someone who gets that notification consistently might be better to test.

@@robotlawnmowersaustralia7913 it's super cloudy right now, and it was sitting on the charger with the camera symbol. I checked back 30 mins later and the camera symbol is gone, I tried to tell it to start but it won't. It's not dark enough yet for that to be a factor. Hopefully it will charge to 80% before it is too dark. I want to see if it will auto leave or not. Maybe the camera locating ability is getting reset when it gains a sat fix intermittently...?

You are right. And we will keep the position system working even if it is dark and no satellites signals as long as it is charging in the future firmware. Thanks for your explanation.

From what I see around the world on youtube, we seem to be pretty lucky in Australia for the amount of GNSS satellites we see in the sky most of the time.

@@robotlawnmowersaustralia7913 Since the last update in germany I have to wait about 3 minutes for repositioning. Can drive around manually, but nothing happens. And then in this video - "Bam, oh i'm here"

I will test this again. you could definately be right.
