Project 'Landlord'

Open source firmware for Worx Landroid robotic mower.

Similar projects worth following
Reverse engineering and develop a new and open source firmware for the Worx Landroid robotic mower family. Add new features. Smarter algoritm. Add GPS for smarter navigation.

DB275 models uses a NXP LPC1768 arm Cortex-m3.
DB504 models are very similar to DB275 but uses a NXP LPC1788 arm cortex-m3.
DB297 models - please share images!


IC's on DB275-10:


IC's on DB504-03:

The onboard bootloader checks USB after memory stick after firmware file and flashes the its contents.
Custom firmware does not overwrite the bootloader, so it is possible to revert to original firmware.
DB275 firmware start at 0x9000
DB504 firmware start at 0x10000


Source code: https://github.com/Damme/LandLord

To setup build enviroment follow How to install the ARM toolchain
Also possible to use KEIL-MDK.


Please feel free to donate money.
I currently own thrr landdroid's. Two 791e 2015, 794e 2014 - with DB275 motherboard and one wg791e.1 (2016) with DB504.

    Hello all, I am getting quite a few PMs about this project.

    I recently started programming again with the goal of making the firmware able to talk to OpenMower. https://github.com/ClemensElflein/OpenMower

    The code on my GitHub is NOT READY YET. At the moment lpc1788 version of the code compiles but not the lpc1768. I am prioritizing LPC1788 at the moment but then that is somewhat ready for use I will start looking at the lpc1768 code again.

    Pinout diagram can be found at https://github.com/Damme/LandLord

    Hello all!

    First of all, Sorry for not answering you guys at all more or less. Also, I just noticed the link is bad to the io diagram so here is the link again:
    https://drive.google.com/file/d/0B98aBL1DeE4uc3hLQUhHa1FXUGs/view?usp=sharing&resourcekey=0-qmhrLCdqSrvEi-HP7xEJgg

    And the progress? Well there is none. I didn't have energy or time to continue at the time and I also hoped that competition in the market would make the machines better. Not WORSE what I can see they went. So in my eyes the competition only made companies want more profit from existing customers... Sadly.. 
    I also made some progress with DB504 model. I made both 504 & 275 able to move around, start stop mower, start stop charging etc. but this is where I stopped.


    There are techniques to have GPS based navigation down to a few cm position (With RTK gps base station etc)
    I am pretty sure it would be possible to program a simple map only with compass and length meter too, it wouldn't be precise at all but I'm sure basic navigation with this technique would be possible, especially with the modern mcu:s that has a lot of compute power.

    So where am I with this project today?
    I am still interested in developing a new firmware. Especially since no progress have been made at all what I can see in the market..

    Worx still seems pretty cheap and rather easy enough. I don't have any motherboards from the later year models at all. Hopefully they haven't changed much at all but I have no idea.
    So if anyone out there would like to dokument, take hi res photos (Without a potato camera please!) I might be able to cross reference the different models. If I would continue this it would not be very smart to use a soon 8 year old robot for this. but if the motherboards are close enough the code could be somewhat universal.


    Hopefully some of you that are truly interested in this project developing a new firmware are getting this message and maybe we can figure something out together.

  • Different motherboards.

    Daniel Wiegert06/20/2016 at 21:16 2 comments

    I've been working on mapping 2016 year model of worx, they use DB504 motherboard. Usually .pck-firmware, its a container and the start is plain-text. It's possible to do a splitter for that but I use dd to copy out the firmware.

    DB504 probably use LPC1788. I've been looking on some io's on a picture I've recieved and it seams to be correct. (not possible to read chip text without removing the conformal coating)

    My guess so far is U10 = spi flash. U11 + U12 compass / accelerometer / gyroscope. Yellow tape protects JTAG from the coating

    Display and Keyboard are the same as previous models. Wire sensor uses a daughter board:

    Should we assume they still uses LPC and that this might be an LPC11U6x?

    Wifi module are supplied from http://www.redpinesignals.com/, uses SPI (SSP0) communication. easy to mod! :)

    ( https://www.ghielectronics.com/catalog/product/282 looks like a suspect...)

    So far I've been developing and reversing DB275 (2015 WG790/791/794) It seams all 2016 has DB504.

    WG796e (2015) uses DB297 which I haven't seen yet. So if any one wants to send in pictures of that motherboard it would be very appreciated!

    I don't know much about earlier versions.

  • Some / Slow progress

    Daniel Wiegert06/07/2016 at 09:05 2 comments

    I had a small break, I let the mowers do their job outside! :)

    I've figured out the boundary wire and how it works. I finally got the idea to use the USB d+ and d- (p0.29 + p0.30) and output of p0.7 - p0.10 and measure with oscilloscope.. :) (4 wire inputs -> raising and falling each on pos / neg)

    The blue is probe directly on the boundary wire.

    So if negative measurement is before or after the positive, then you know if you are inside or outside wire.

    p0.21 select amplification or something, you can detect if you are within 1 meter of the wire or not.

    p0.22 probably selects between left and right sensor.

    And if you are close to the sensors you get some weird artifacts in the measurement, longer pulse, and even more than one pulse. It seams this is following a pattern and it might be possible to user and detect the distance to the wire at 0cm, 10cm, 20cm and 100cm.

    And the last one, wire right on top of the sensor.

    One guess would be that the un-populated IC nead RTC battery is a SPI flash but not confirmed.

Hi. I was given a "broken" Landroid WG791E and thought maybe I could repair it and then hack it :-)

The first issue was that the power supply was soaked wet, having caused an internal shortcut. Using a separate PSU, I could get to the "base flashing green" state. I have access to the lawnmower's menu but the motors (wheels and blades) don't start, and I thought maybe that was because no boundary wire was detected nearby.

As I don't have the original boundary wire, I just plugged a piece of random wire between IN and OUT and the PSU overcurrent protection triggered immediately (over the stated max 1.5A) !

After putting a 1K resistor across the "boundary wire" connector, I measured a steady 28V DC on it, like it's directly connected to the incoming 28V, but that doesn't really make sense as the "boundary wire" seems to be just a wire with very low resistance, so I suspect the power part in the base is fried too, but it's hard to diagnose as it is fully potted...

Do you have any information about what signal is required on the boundary wire (DC pulses or AC ? Voltage or current source ? Frequency ?)

Any information would be highly appreciated. KR. Vincent

Jonathan Smårs wrote 06/01/2017 at 14:45 point

I've been reading up on this project and it looks really exciting! I'm wondering how far you have come with this? Is it possible to interface directly with the steering of the mower? If I could access forward/back/turning directly, I think I might build a DGPS or similar location system to get much better cutting.

Also, is there anyone experimenting with alternative batteries to get faster charge rates, giving way more up time and thus larger cutting areas?

  Are you sure? yes | no

Great tear-down! 

I recently purchased a Landroid S 500, and found my self wondering if there was anyway of getting it to be a bit smarter, so I found myself here :) 

One improvement that would be nice was a better "return home" function. Mine just follows the boundary wire all the way to the charging station (through all zones)... 

My initial thoughts was that it would be nice if it was possible to add "shortcuts" to the boundary wire - maybe in the form of rfid tags. The mower could be programmed to react to each tag by making x degree turn, in-order to point it in a direction in witch it would reach home faster :)

do all Landroid's return home in this way or do som have a guide wire like the Husqvarna?

  Are you sure? yes | no

Fabian Olesen wrote 05/13/2018 at 14:27 point

This is great work! I have a parallel interest in that I'd like to identify what the on board processor's I/O port functions are so that I can cut signal output traces and replace the processor with my own CPU/WiFi/GPS. Has anyone identified the I/O line functions of the board's processor? Don't own a Landroid yet but this looks like it has lots of potential. (Edit) Great! I found your mapping. Superb!

Interesting project. I have a 796E.1 without wifi. I can see redpine is delivering the wifi modules, but which one exactly. From reading the comments, upgrading to wifi would required 1 wifi module and a change of dip switch settings under the grey plastic (set to 0001?).

I'm now the proud owner of a WG796E.1 and want to update the software to V2.21. It sees the USB drive but the mower doesn't seem to find the update file and shows the PIN screen after some seconds without performing a update. I have correctly formated the USB drive to FAT32 and unzipped the firmware zip file. Does any one of you have any simular experiences.

Problem solved. A different (smaller) USB drive did the trick.

Will this firmware work safely with WG790E? I am running original latest firmware (ver 0.94) and It very often happen that when charging it simply shout down in unexpected manner, so to charge I have run it again providing pin code. I believe this is some firmware issue. Probably when battery temp is to high it simply shouts down - in my opinion it should simply wait until batteries cools down and then should start charging cycle again.

The behavior is so annoying that think I will swap the firmware to yours. 

BTW. I am .NET developer so maybe I can help somehow in a future

Firmware is not a replacement just yet .. :) So don't bother at the moment!

Just bought a new WG796e.1 and a broken wg794  to play with. Unfortunately the wg794 was more damaged than I thought, motherboard was totally busted so I'll have to look for another one for testing. But battery and motors were OK. Since there has been some discussions regarding the battery I took the wg794 battery apart and there are seven Sony 18650 1900mAh cells in it.

Too bad about the motherboard! :( Could you take some images? I bought a lightning struck wg791e.1 and I managed to repair it after some checking around. Some components were obvious (cracks) and some were harder to find, but over all, it was the power management part of the system so the CPU started if putting 3.3v direcly to it.
Regarding batteries.. 1900mAh.. Wow! Thats not much.. I think I'll upgrade mine asap ^^

Well, this motherboard is beyond repair i'm afraid. It has been subjected to severe mechanical damage. The board was bent just under the processor so bad that the processor had popped off the board...
