[Botvac] Erreur 3000

[rinkan]

La voilà, je l'ai mon erreur 3000 avec mon Botvac.
C'est arrivé progressivement et, aujourd'hui, impossible de démarrer.

Je remarque que c'est le Lidar qui ne tourne pas.
Je fais un reset robot, reset batteries, nettoyage compresseur = aucun résultat

Je connecte mon robot en USB et lance Neato Control.
Et là, surprise : j'arrive à faire tourner le Lidar et celui-ci scanne l'environnement.

Qu'est-ce qui cloche ???
Pas le moteur du Lidar donc. La batterie ? Elle avait toujours une bonne autonomie jusqu'il y a peu ...
Une idée des tests à faire, notamment avec Neato Control ?

Merci.

When the Botvac is cleaning the load on the battery is much greater than when running the lidar over USB. If the battery is weak this will produce operating voltage too low producing intermittent failures of many different kinds.
The voltage is reported in Neato Control.
You could in Neato Control turn on the fan and the front brush for about 1/2 to 2/3 cleaning load while repeating the lidar scan.
Off the dock on battery power.
For Botvac a filter should be placed against the fan intake behind the bin. USB port under the bin.
(I have also used a cardboard cover over the bin cavity, not needed here.)
Leaving open the fan will increase the load even more. The fan is regulated to a fixed RPM.

I am not sure what motor features are in Neato Control. For text commands
Testmode ON
SetMotor Brushenable
SetMotor RPM 1200 Brush
SetMotor Vacuumon
...
SetMotor Brushdisable
SetMotor Vacuumoff
Testmode OFF

Problems with the lidar motor and belt can be intermittent, difficult to reproduce.
The lidar motor is inexpensive, standard CD player motor. Several users replaced.
The bearing can also accumulate debris.

There is no guaranteed solution. Too many parts.

Thanks glnc222 !

I had a little doubt about the battery but, so far, my Neato was running cycles as long as before.
I saw the values related to the battery in Neato Control but no way to know if they are correct or no.

Will do more tests this evening according to your suggestions.

The fully charged Botvac battery will show an unloaded voltage over 13.5v and drop a volt under load. When the voltage falls to near 11.5 or below under load 2-3 amps, Neato returns to base for recharging. 10v is the minimum allowed voltage below which cells can be damaged, full depletion; Neato never goes that far and maintains a 30 per cent capacity marging against damaging deep discharge. The unloaded battery after a maximum run may show around 12v. There is a "discharge curve" of voltage change over the course of running published for different battery cells. Botvac has 10 cells in series for NiMh, compared to 12 in XV models. During charging, a voltage up to 2 volts higher is applied to push charge into the battery, topping around 15.5 volts. The unloaded battery voltage will then decline over a few minutes from near 14v down to 13.5, depending on age of the battery. As the battery wears out, the top voltage remains the same but with lost capacity it discharges more quickly. Rapid charging and discharging, shortened run time, is the signature of battery wear. Run time can be measured with the LCD warranty display screen showing the cumulative run time in seconds on the top line, in hexadecimal numbers (convert in Google).

I went abroad for 3 weeks and i switched off my Neato.
After i came back, it works perfectly, no more error
