Fascinating, thanks for sharing! If it continued to perform like that maybe it’s worth designing a 3D printed “clip on” structure. I think I have some reflectix the basement too so will give it a try next opportunity I get.

Let me know if it works for you and if you share your clip design I may print and use it. Painters tape came off today.

Sounds like it’s time for me the jump in the 3D-printer party. Lots of little things I could use it for. A little off-topic, but what printer do you have?
I have an ancient Lulzbot Taz 6. Purchased in May 2017. I keep hoping it’ll quit working so I can update to a new one, but it just keeps working…

I’ve been FDM printing for over 20 years and have had and tried and built countless printers.If you want something to be used as a tool, not a hobby you have to tinker with, get a Bambu Labs. This has become controversial to some people in the community because it is not open source and Bambu has locked down their network protocol. If you want to research there are reviews on youtube from Makers Muse, CNC Kitchen, Uncle Jessy, Teaching Tech, Modbot, and many others. The ones I listed are the sites I reference all the time. Bambu Labs are one of a select few printers I would consider plug and play. They are great for beginners. I set my 6 year old nephew up with one. I’m not a Bambu fanboy, I have four other printers I still use. I just find Bambu to be the one that I dont have to troubleshoot as often. They are also some of the fastest printers on the market with great print quality.

Until the Taz dies, it’ll be my go to machine. Very little troubleshooting with it. It’s a workhorse. (that is a model lulzbot offers now)

plus a second $1,100 battery
charge inside out of the heat ready whenever
your money + your time = problem solved

Don’t laugh - cord + battery is a solution I’m sure many of us who own the snowblower have considered. It would be nice to be able to swap in a fresh battery and keep that machine going sometimes!

Same thing with me today!!!

How about some more ideas? I’m looking at some fans, maybe Yarbo can think about adding some internal fans? 
Hope this helps someone. Multiple sizes to fit.
I think if they offered a replaceable battery cover that had a solar mounted fan on top with some extra clearance it would really help. Maybe even make the cover yellow to reflect more of the heat. Swap it out for the original for the fall, winter, and spring.
I do think this is a very good opportunity for Yarbo to officially create and offer shelters for sale as an option. GPS issues while docked in the shelter could be mitigated by adding an option for the user to specify to pull straight forward off the dock 0-5FT in .1 inch increments, stop, acquire GPS, and then execute an auto plan.

This is not going to be a simple fix. I haven’t seen any official response to the issue.
Yes, this!!!

If they makes an official structure with known dimensions and connections to the charging base, then multiple visual reference marks can be used for accurate visual based docking.
I’d buy a yellow summer battery cover with a higher profile and baffled ventilation on the vertical edges of the left and right. Anything would help. I let mine run in the long shadows with the cover off, but charging is the real heat maker.
Seeing how this goes. Climbed from 35 to 41 C. Strapped this on and the painters tape held through the roughest part of the zone. See how it does. Heat index of 97F, 87F with high humidity and only light breeze. We’ll see if the humidity gets the better of the tape.
Just an amazon “usb stroller fan” my wife bought years ago. It was so useful I bought a bunch. Great for boat bilge work or to mount under the t top. I use to keep help my NAS cool when its cooking on a big transfer.
it lasts about 8 hours on low. I have it on medium for this mow.

Started waffling between 40/41 C but now holding 40. This zone and cut direction have tons of turns and short runs so the motors are torquing frequently. Would be nice to see it in the high 30s but with these conditions I’m not sure what more it can do.
I have not completed a mow with yarbo that I didn’t have several issues throughout, I have 1.7 acres so it should handle it easily. But it takes about a week with all the problems, on third rover and 2nd mower, latest problem is charging, they say it’s the battery overtemp protection, took them a week and a half to tell me that, they suggest mowing at cooler temps, also offered to send me a direct battery charger and said “to make things more convenient for me” what tha, how is plugging up and “autonomous” robot convenient, besides if it is the internal battery temp sensor preventing the battery from charging it still wouldn’t charge or be good for battery to charge…and that was from real tech support.
Summer just started in Louisiana and there isn’t going to be cooler temps for a while… when I mow at night I get track slippage errors and it sits there til morning, I get motor overheat errors often and it just sits there, why not go back and charge while motor cools and periodically reverse blade rotation to reduce clogging. I feel like they rushed yarbo to market and didn’t do enough real world tested, when I purchased last July (received late January, didn’t say I was preordering) it didn’t say features such as tow mode, trimmer, etc wasn’t available yet… my yarbo has to be set 4” in from perimeter, house, fence etc, and doesn’t drive very straight along house or structures, I don’t see how the trimmer is going to work, without looking like crap. As much stuff gets packed under mower deck with disk blades i feel it will pack even more with mulch blades. I am not impressed, just 1 problem after another, I spend more time each week trying to get yarbo to mow and dealing with customer service (only get tech support after a few emails) than if I was just to go outside and mow. I have some white plastic sign film, maybe I’ll put that over the top cover to reflect some heat. What other product have you ever spent this much money on and had this many problems and not got a refund already. They used all our free feedback and problems to design the pro mower, which they should just recall the M1 and give us the pro mower we helped design it. I did not sign up to be a product tester, although we all have been, I feel like yarbo is the owner and I’m the slave, spend all my time trying to make yarbo happy. The vision or ultrasonic is useless if you have seed heads it thinks they are all obstacles.
I’m about ready for a refund. Thinking of checking out Lymow, it has metal blades, deck that lifts straight up to clean, it’s not a tow truck but who’s towing a car or boat with yarbo other than playing around, I just want a robot to cut my grass Autonomously, the Husqvarna 120s I had worked 24/7 for about 2 yrs with very few problems, it just couldn’t handle much yard.

This is because they put a polar bear in the desert and it just isn’t surviving. Rover and its battery are clearly designed to stay warm. And black is to reduce snow.
In my experience, mowing isn’t when the battery overheats. It’s when it charges that the heat really builds up.
That is my experience, yours may be different.

You are exactly right Ken. The issue is not when mowing but when charging. Google other competitors mowers and see it’s a common issue across the industry. Batteries don’t like heat and charging generates heat. Yarbo is looking into solutions like trickle charging and potentially other ways to help.
Some shade and active cooling would work wonders. Fingers crossed for a solar powered fan battery cover and a Yarbo shelter.
