I use many IMU into different chassis ,each time the imu cable is between 10 and 40 cm without particular issue, BUT you need to avoid that this cable don't touch motor or DC/DC voltage regulator. :ROFLMAO: :ROFLMAO: Using the standard config with perimeter coil reading ,you can easily see the...

I confirm that xbee LR module are perfect and work for me on large area with 1 base station and 2 rover without issue. WIFI have some trouble on long range with tree etc... Other solution is certainly LORA on ESP32, i test them in the past and they work at long range (200 meter) into garden area...

Hi. Has anyone ever tested a receiver other than the UBLOX F9P What about : UM982 or UM980 ...

If it's GY87 you can't change I2c adress, so if you use sunray you need to remove the RTC module to have correct I2C working mode. Don't forget the GND. and 3.3V shunt on JC2 https://wiki.ardumower.de/index.php?title=AzuritBer_Firmware_(English)#GY-87_WIRING_TO_PCB1.3 Best selection is GY-521...

I think the price is also something to consider for a DIY project What kind of camera is able to detect grass and give a distance for 100 eur. Now for the ardumower community i think hardware like : RTK , LIDAR ,depth camera are all very expensive technologies. ROS is also not so easy as...

Not exactly in the luba wheel ;) Hoverboard wheel is direct drive, the Luba wheel motor have a gear box and this allow low sense for high torque and this reduce the max speed comparing to hoverboard motor.

You don't build a lawnmower but a brush cutter (>50Kg ??) 😂😂😂😂😂...

For 4WD mower : MAMMOTION LUBA2 is really a very good mower. Motor are include in the wheel (same as overboard but build for low speed) and have a very very high torque at low speed.

For very large area ,you can take a look at Robomow RL2000 or vicking same model https://www.leboncoin.fr/ad/jardin_plantes/2170383346 It's very large mowing 53 cm can mow 400m2 /h using sunray RTK solution https://www.diy-robot-lawn-mower.com/threads/rl2000-goes-teensy.102/post-2314...

Are you sure it's error and not simple warning ? It compile on my side with samd 1.7.16 Check the installed library into arduino ide Certainly you don't have the correct one.

On very high and wet grass it's certainly possible that the mow motor noise generate the issue.(big load) It's something i always see with DUE and PCB1.3. Trouble is really reduce with teensy adc decoder.

Normally no particular issue on PCB 1.3 for perimeter signal line. Possible EMF Noise from motor. Did you try to deactivate the mow motor and test again. Also water in receiver or coil ?

Why do you want to use Mega or Due, they are very old MCU ?

Certainly LORA ESP32 is also possible and less expensive than XBEE module, but need some dev and adaptation. LUBA mower use this kind of tech to sedn correction from RTK station to ROVER with a big sucess.

You have a low band filter on voltage reading,so it can cause what you see. But normally not a problem if battery is very low charging process need to start correctly. Try to mow up to 23.5 or 24V and send mower to dock to be sure.

Odometry is mandatory to have a correct working. Only 1 signal cable is strange : Are you sure that this motor have ticks count by rev (it's odometry) ?

Here the link for robomow RL1000 sunray. It's PCB1.3 with standard drive motor MC33926 and 3 BTS7960 with 3 ina226 for mow sense measurement. https://github.com/Boilevin/230723-095950-adafruit_grandcentral_m4 To remove mow motor nr 3 sense reading , you need some change into amrobotdriver.cpp...

Take a look at Firmwares overview in the wiki: https://wiki.ardumower.de/index.php?title=Hauptseite

Not sure , but it's possible that in dock recording when mower detect charging contact the location is update to map registering and a distance is add behind station to have a perfect docking contact. So what's append when editing a docking trajectory, maybe it's better to uplug it when record...

Why not i test this solution: solutiontimeout is also reset inside // UBX-NAV-RELPOSNED. In all case i don't really understand this feature and why only in the GPS part. ???? If GPS freeze ,normaly watchdog stop the robot, else there is a solution in the ublox message ???? Unfortunatly don't...
